[@leszekostachowski549]

It reflects thermal radiation, but is cold in itself. Air gap insulation is needed on the body. To hide from the camera, something at ambient temperature is needed. A material with voids that quickly takes on air temperature and without contact with a warmer body,

[@johnmclain250]

Oh I have some actual helpful info about this as we were testing thermal and ways to avoid it. We tested space blankets (mylar) and had mixed results, it does work during a warm day, but not at all when it's cold out. We tested a bunch of other materials, but what actually worked best, was cardboard. Not even thick cardboard, any old sheet of cardboard completely blocked any and all thermal signatures. We were only able to find each other when either a body part was exposed at an angle, or if we saw a spot where the other had been lying/sitting down previously. (Warm spot) After they re-positioned themselves and the cardboard sheet.

[@DAVOinIN]

Optical Physicist here: The reason the mylar looks black is because it is acting as nearly a perfect mirror so what the camera is actually seeing is a reflection of the sky which, depending on humidity, dust, surface temp, etc... For a normal, clear, 5°C night in the desert it will be -30°C, which is a huge temperature difference from the background at 5°C. In the forest like this it is probably closer to -9°C, which is still a 14°C differential.

[@Noneyabiz001]

I’m a fire fighter and we were doing smoke training with thermals. Basically we fill the room with smoke so you can’t see. We hide a victim somewhere in the room. Then you have find the victim using thermals which is not as easy as it sounds. Because they usually hide the victims the best they can. One of the guys had their kid there. His kid wanted to play the victim. So they hid the kid under his father’s bunker coat and he didn’t not show on the thermal at all. The Nomex in the bunker coat is meant to keep 800* out so it has no problem keeping 98.6 in. We also tested this with the jumpsuits and boots we use for brush fires and a Nomex hood the only thing the thermal camera picked up was where the eye weren’t covered. This was like ten to fifteen years ago haven’t tried it with modern thermals but I’d be willing to bet somebody wearing Nomex would be hard to spot

[@C420sailor]

Here’s the deal with nomex. It doesn’t keep heat out per se…it has an insulating capability somewhat on par with normal fabrics. What it does do is char away under direct flame impingement, instead of burn or melt. Bursting into flame would be bad, and so would your turnout coat melting and sticking to your skin. What makes it so effective against thermals is that it’s thick and bulky. A heavy blanket of normal fabric would perform similarly. Think about your nomex flash hood on a cold night. It doesn’t really insulate you any more than a wool hood of similar weight.

[@BR-gc5uo]

Well the idea here is that the jacket's externals are at ambient, and internals are at human, or insulated human, temp. After enough time, the bulk sheet of the jacket will raise the entire thermal mass of it up, so it's only going to be useful for minutes (hard to say how many, 15 to 30 intuitively) before the user will be required to expose themselves and allow the jacket to cool to ambient. That said, a more distributed heat along a larger surface that is more likely to be closer to ambient is more likely to make you harder to spot, as it may look like a reflection as opposed to a human, which we're adapted to spotting. If you're clever and have an understanding of the drone's direction and view, you can stand back to gap yourself from the jacket to allow air to take some of that heat instead of the jacket. Hot air doesn't show up on the camera nearly as well as hot objects.

[@Noneyabiz001]

@@C420sailor you’re right but a turnout coat does protect you from heat also. The number one reason why firefighters die is our equipment. Because the equipment lets you get into places where you shouldn’t be. Your bunker gear will protect from extreme heat while also not melting around you or burning. The problem is the higher the temps the less time you have till the gear reaches critical. You’re a sailor so I know you have some firefighting experience. I’m also pretty sure you have had some live fire training. You know as well as I do if you’re in a burn building that temperatures can reach as high as 700°or higher so you are being protected from heat not just fire. The way insulation works, if it’s keeping it out it’s gonna keep it in.

[@USFighter]

[@TheVergile]

mylar isnt a bad idea per se, as it blocks a large part of IR and is a great insulator for thermal energy. But you would need another material on top that easily equalizes to ambient temperature. Any good thermal cloak needs to have two properties: the outside needs to be at ambient temperature and have the ability to quickly heat up/cool down. But it also needs to be well isolated to the human body so as to not take on the body heat. Mylar only does the latter. (plus it makes loud crinkly noises). A better solution would probably be using well insulated clothing and or blankets which are covered with another material. This can also double as visual cover (think of a ghillie suit)

[@heathermillsphantomlimb9314]

I think a good experiment would be to increase the thickness of blankets or something similar to see how quickly it would heat up and give you away (because it might hide you for a few seconds, but it would heat up pretty fast). For instance, I wonder if using a piece of 2 inch household insulation might work, even for just a few minutes? It’s made to trap heat, so if you pointed the paper side away from you, perhaps it would work for awhile? It would still be light and flexible, but it would also be quieter than a Mylar blanket. It would also be a little more readily available, since the target could tear some out of a house they were hiding in. I don’t know, just thought that would be cool to know.

[@artificial4612]

While such materials like Mylar block emitted heat, their reflective properties can create stark thermal contrasts, making them counterproductive. Effective strategies require a combination of techniques, including insulation with absorptive layers, environmental blending, and active cooling methods. Additionally, leveraging natural terrain and introducing competing heat signatures can disrupt detection. Ultimately, evasion success depends on understanding the interplay between body heat, ambient conditions, and the capabilities of thermal imaging systems.

[@andrewdreasler428]

Mylar blankets keep you warm by reflecting a large portion of your radiated body heat back at you. The infrared camera cannot 'see' any radiation from the blanket, as it is SO reflective in the IR spectrum that all the IR 'light' is bounced off in Specular reflection (like a mirror) instead of Diffuse reflection (like a white sheet of paper). I had a project where I needed to use a vision system (a 'smart' camera) to inspect foil-lined caps for flaws. the foil lining reflected so much of the light from the ringlight back that its pixels in the image were 'super-white' (reflecting more light that a pure white object) so it was easy to spot in the image. any wrinkle or bulge in the foil however, threw all the light hitting that spot outside the camera's field of view, making it 'super-black' in that area, again, so easy to spot.

[@bassproshophat8999]

Instead of dropping altitude down to tree level the zoom button will work 😂

[@IdentityCrisis1581]

I think it's the reflectivity. It traps heat when you're under it, but the outside is still reflecting heat from the outside. So I think that is what is being picked up on LIDAR. You notice that it kind of flashes in and out of visibility like a bad green screen effect. I think at certain angles it is reflecting the heat at an angle that the camera doesn't pick up. It's still not going to help because there is no way to maintain that specific angle.

[@johnjames5842]

[@captainz9]

Here's the thing, you do NOT want to wrap it close/around you - you want to be in a hole/depression or covered with branches, etc, with the mylar over it and then preferably some other cover over it. It'll help reflect the heat/IR with some distance, but like a mirror if it's too close to you the blanket will still show the heat difference.

got to get deep in the deep woods completely covered. I have been through S.E.R.E. training in the USAF, when I was a physician in the air force. Go as deep as far as you can; go where no one would go, when you evade.

Umbrela seems to be comically super-effective

[@Brandon-Kraemer]

If you get a large umbrella and cover it with foilage and such that's near u, it's barely visible. Hiding near a trash pile and using cardboard or such over it conceals it very well

[@andyvonbourske6405]

i remember seeing it work with older generation nvg's . but the newer ones are just too good.

[@stcredzero]

There are times, when it looks like it's spread out and mostly reflecting the terrain, and in those moments, it IS invisible! I think the real lesson here, is that mylar blankets can only be used to reflect IR signature from one direction into another direction. So they have to be spread out and held flat in a frame, and then they can only be used as directional shields.

[@jgrenwod]

Hot Shots that fight wild fires have a thermal blanket that they cover themselves with if they are trapped. I saw it tested as a thermal shield to counter military night vision (ANVS 6?) and it worked perfectly.

[@Sergeantgrunt]

Anything that can shield you without touching you can potentially work. As long as you have an airgap to stop your body heat from coming in contact with the object you are using. The downside it thermals are getting much more sophisticated that they can see the irregular shape of said object. The drone can see the tree trunk differently than the needles. I feel like they didn't give the mylar blanket enough time to adjust to the outside temperature, which is key to defeating thermals. Yes, you'll see an irregular shape but you won't see what's on the other side. Now, if you see 12 irregular shapes all similar in size, you might wanna think about what's making those shapes all in the same area.

[@rongee3707]

Which is why you need another blanket, burlap so it covers the shine, and holds the ambient temperature! Camo up the outer cover, and you're good to go!

[@lamontgarnesjr4638]

Do Mylar and a poncho liner, have the poncho liner outside in the same ambient air temperature for a while (as it would be) then have the dude prone out with the Mylar skin side…you don’t have to post the results. But you’ll see a substantial improvement in thermal efficiency and less deviation with the ambient air temp. 😉🛸💨

[@lamontgarnesjr4638]

Mylar reflects your heat back to the earth, poncho liner masks your thermal signature…you’re trying to provide yourself temporary cover from drones and flybys…nothing on the civilian market will mask your thermal signature during long term operations…eventually your body heat is going to radiate and light you up like a Christmas tree.

[@Brocuzgodlocdunfamdogson]

Try testing a water saturated diving suit. The evaporation of the water should have a cooling effect on the outside of the suit.

[@crazy4milsurps]

One thing is it's not supposed to touch you, it's supposed to be a way from the body. Doesn't make it work perfectly but if it's above you and not catching and radiating your body heat it helps

[@jkbrown5496]

well, yeah, all the mylar does is reflect some of the infrared radiation back toward the source. It will still heat and radiate a smaller signature. Or as seen block the background heat radiation creating "cold" spot.

[@gmz1997]

Well you aren't going to try to hide in the open. lol Also, observing the changes? Stick that under the tree with separation to a human heat signature, let the blanket adjust to the temps and then fly over looking for it. Then make the decision to either engage or not, giving away your presence. These small drone have short range operational distance.

[@atlas4733]

Since a thermal camera just counts photons, the low emissivity (which means the blanket emits much less IR photons for its temperature) means that the camera will count it as a normal emissivity object that’s just really cold. Thermal cameras assume all objects have a single emissivity (default is 0.8, but you may be able to change it) and that is mostly true. My source is my thermo professor

[@reddragonflyxx657]

Yeah, IIRC `emissivity + reflectivity + transmission = 100%`, and clean Mylar has an emissivity of like 4.4% with negligible transmission, so it's a >95% reflective mirror in IR. Mirrors aren't good for hiding in a glowing forest under a dark sky (effectively what this test environment was), at least not from many angles. They're good as part of your insulation, which helps keep the outer surface of your hiding place near ambient temperature.

[@Sapper_Rage]

This channel is the real MVP 👍🏽

[@the.happy.mechanic]

Try a heavy welding blanket. Although anything you use besides dirt and a lot of it will show up as a void on the ground.

[@dudester873]

I didn't know this -- thank you for this information. 👍

[@jaspervaneck3258]

Only real solution is covering yourself in something in the environment., having an insulating layer (bubble wrap or an insulating blanket) under the covering should extend how long the covering will remain close to ambient temp. In short, if you're on the move, it's unlikely to work, best to get under cover somehow. Anything with significant thermal mass that fully covers you will do the trick, provided it's at ambient temp.

[@therealboi1335]

When i did military service here in Sweden, we were taught that there is no real portable way to defend yourself from thermals except thick blankets, what they told us was, if your fighting someone with thermals you better hope to have anything blinding and loud.

[@hu5116]

It’s called (amour other things) inverse contrast. Whereas the body is hot, meaning it has high emissivity and a high temperature, the reflective blanket is…. Reflective. Meaning it has near zero emissivity. The radiated energy is proportional to the product of the emissivity and the temperature, so an emissivity of zero means no radiated energy. This produces a black spot in the imager (or visa versa depending on the settings). The key thing is that the imager detects DIFFERENCES in the radiated power. So a bright target on a dark background is just as easy To detect as a dark target in a bright background. Only if the target and background emissions match will the target seem to disappear into the background. This is often hard to do.

[@fsully3379]

Kudos to the dude who actually went out with the Mylar blanket

[@distrologic2925]

you need the mylar blanket with a pattern. It should block the EM radiation from your body but its so clean that it looks unnatural. Some kind of reflective camo patterns or foliage might help merge it with the surroundings

[@russell7386]

They make a composite board for use in attics.Its 110 degrees while I work in California.Walk past board an is like no sun.

[@Ziptietechnician]

Mylar reflects heat. It would need to be layerd between fabric. Even then only good till the material warms up. Would be easier to just walk with the cattle.

[@aj-us5qp]

Thank you, that was interesting. 🤔

[@quarry1030]

Mylar inner liner gille. Of course, you would overheat extremely fast, but it would work.

[@ipenguinpod]

I think you are seeing the atmosphere and that is why its so dark? Because it sorta looks like part of it reflects the ground and so it blends in, but then right next to it is a massive cold spot relflecting space. With a drones constant changing position i think mylar is always gonna pose a risk of reflecting atmosphere and making you a nice bright spot.

[@HyperLuminal]

Just out of pure curiosity I’d be interested in how an LCG of LCVG would perform under the gaze of thermal imaging. Obviously it wouldn’t be remotely feasible as a solution and there would be clear problems with the onboard power supply, the heat exchangers, and of course the ventilations aspect of the LCVG specifically. That said from a solely academic perspective testing and observing how the technology performs could prove to be valuable data. In both earth bound and space based utilization the garments were successful at lowering core temperature and maintained the ideal levels. This included being inside of inhospitable steel mills, as well as intense fires/wildfires, and of course the near vacuum of space. If something can keep you cool and dry while surrounded by searing fire, and can also keep you warm and cozy while on an EVA in low orbit I would posit that there is a likelihood this garment or suit could potentially be used to match the ambient temperatures of an environment and mask a thermal signature.

[@Rakesh-ec2pz]

I'm watching these as a regular citizen just in case all the shit hits the fan, just to educate myself If I end up on a frontline to help my baltic friends out ✌️✌️✌️

[@Ragnar676]

Yeah but what most ate forgetting is this is helpful but cause of this it is mor effective if I'm not mistaken when used to lime a gullies suit of some kind. The outer gullies suit helps even out the rest of that temp shown here. The key is to get very detailed in the used of the object and not be sloppy about it cause like with anything sloppy work gets sloppy results. This is a very rough concept but will never realistically be effective at this degree of effort and use of a mylar blanket against thermal. Useful ut again as noted attention to detail and max effot towards efficiency is a must for it to be done.

[@KhattaRapidus]

idk glass tiles or fiberglass inside some kind of blanket. maybe camo pattern material and some ghillie. You indeed need another type of insulator to keep heat from being transferred to the glass, glass heats up.

[@FerociousSniper]

Honestly, the umbrella is GOATed.

[@dumpsterfriar6732]

Don't touch the mylar, use it as a sheet. Your body heat will rapidly heat it, you need to keep it inches off your body and use it like a shield.

[@Beelzebuds]

Thermal is simply something else... My thermal optics pic up thermal reflections in brushed stainless steel that does not create reflections in visible light. It is amazing that somehow thermal imagine is maintained even with the variation in surface consistency.

[@tomb2289]

Aitäh! Love these snippets lads 🇪🇪🇬🇧✊️

[@lanesworld4000]

An umbrella will hide a person from a thermal, and it will keep the rain off your head, too 😅 when you're not playing hide and seek.

[@everlastingmedia]

Well, a good mylar blanket will work better than not having it, IF you aren't touching it. if you're transferring your thermal energy to it, of COURSE it's going to be just as visible as without it. But if you have a basket with the mylar blanket over that, and aren't touching it directly, eventually it will temperature match the environment and make you invisible to thermal. But it takes a bit. you'll get better concealment from a foliage wrap.

[@mawa9843]

If you get a mate finish on the mylar (chalk spray might work well), you retain the isolation feature of the mylar without it reflecting the infrared radiation of the sky and surroundings. This should then conceal the thermal signature much better.

[@kikihun9726]

Watching a shiny/mirrored thing with thermal camera will give you edge case values like really low or really hot. They reflect or deflect any infrared radiation.

[@Zampther]

Not at all an expert , but through work i learned that its not just temprature but how well the material radiates and or reflekts infrared. sort of in the same way that a block of metal feels colder than a block of wood ewen though they are the same temprature due to the metal is a beter heat conductur than wood.

[@joeviking61]

Saw your. Video on a cheap umbrella, that works fantastic. Good to know

[@izaakaz6863]

Kinda like how black holes were first discovered. They couldn't detect the black hole itself, but they could certainly detect something invisible affecting the stars around it.

[@LinKongDa]

Thermal cameras use an Area averaging system to determine the temperature that pixel suppose to be. Because milar is a very good thermal resistance quality. The themerature is highly resistance to change it will stand out like a sore thumb in the image. What you want is outside of the cover the same as the temperature of surroundings. How do you do that? hell if i know. but generally there are 2 issue . 1st your own body heat. 2 the surround temp. For no 1. you need to suppress you body heat. hide and/or pump it elsewhere. mimic or steal the thermal (info) from the surround without disturbing the temperature gradiants. aka cover yourself with the bush but wear gloves when doing the cutting.
