Stupid Thermal Imaging Tricks

[@paulinajan8909]

Great explanation of where infrared falls on the visible spectrum. Your demonstration o the door shows it's important to remember this is not x-ray vision. In the technical side, I can see customers using this in a hunting application get confused when their rabbit or deer disappears behind thick brush or a large tree trunk.

[@matthewreynolds8068]

I loved this video, nowhere else could I find a nicely formated educational video on thermal camera's not enough out there +1 👍

[@mikepetty188]

Thank you Roswell Flight Test Crew. Our company uses the FLIR Tau2 imager except we rotate it continuously in our camera so that we are able to continuously have a 360 degree thermal image panorama for wide area intrusion detection. Thermal Radar is our product. Thank you for the great explanation. I love sharing your findings with my customers to better inform them about thermal imaging.

What a great informative video thanks can I use this thermal imaging to see where these squirrels are going in and out of the house, we've done our best to close up everything with metal over the holes would it be feasible to use a Flir, FLIR brand adapter to a cell phone to film this, and then run it real fast and watch for the blazing hot squirrels in the movie, then stop the film and discern where they're getting in?

[@jackassqwe2]

After the Burn Notice episode, I want a thermal binocular.

[@IAM_GhosT1]

They are friking AWESOME!!!! I absolutely love mine (I also love going on night hikes). I will forwarn you these are definitely not cheap, but for around $2000.00 you can get a pretty darn good one just do your homework and ignore screen resolution (it will be like 1080 screen resolution) but you want the microblometer resolution instead (that's what detects the thermal radiation) your image will only be as good as that resolution. Unfortunately they like to trick you with high screen resolution despite it making no difference as long as it's at or slightly above the microblometer resolution. I/e flir has a 1080p screen but only gets 320 for the microblometer. Moreover check out pulsar there way less money for way better imiging.

If glass blocks thermal, why do lenses work on those thermal hunting scopes?

Is there a preferred color for tricking thermals into thinking it’s a temperature of a certain kind? ie. certain shades of grey or black/white etc or even transparent and coated materials of that. ie. silver but mixed with a specific color palette for better effect or thermal distribution from sun/body heat? sorry for the rambling question.

[@mggm1982]

do we have a thermal paint that enhances capability of my thermal camera as I place my object (painted) far away from it ?

[@IAM_GhosT1]

Yes there is thermal paint, it's designed to reflect space / cold and is aimed at an upward angle or on roofs. It doesn't have to be angled as such but basically acts as a mirror and will reflect the thermal inferred radiation, for example if you aimed it at trees then looked at it it would reflect the trees.

[@lightknightgames]

You know how in very hot conditions, the heat coming off the ground can make wavy patterns in the air, a type of mirage. Does that kind of effect happen in thermal imaging as well?

[@ProApto]

dude, next video on our thermal camouflage

[@tullgutten]

Fog does NOT obstruct thermal but Co2 does (dry ice is Co2) Many hunters use it because of they can see everything in the fog

[@ddegn]

Fog does obstruct thermal radiation. It's just that fog blocks visible light better than thermal radiation. The video shows the thermal camera sees though the fog much better than visible light camera. It's possible to detect CO2 with a thermal camera but the effect is much much weaker than the effect from fog. It would have been interesting to see if the thermal camera could have detected CO2. Usually a special filter is used when detecting CO2 since it's much harder to detect.

[@IAM_GhosT1]

Fog can affect thermal, if the fog is thick enough it will limit your range and details of the object you are looking through the fog at as much like a blanket it does absorb some of the heat. The dry ice was more so in the fact that it's giving off cold. I am a hunter and I have a thermal.

[@timm2020]

Does Silicone block IR light?

[@Saiarts_yt]

I see sometimes on military vehicle give off this mist that conceals them for evading thermal imaging. What are those thermal emitting mist called?

[@IAM_GhosT1]

That's why I didn't go with flir, mine sees the different temp of water in a silver can. Anyway I didn't come here to bash flir, I wanted to mention that you never mentioned my favorite part about thermal imaging... You can see through a tarp or plastic garbage bag almost unadulteratedly, theres a slight shimmer of the bag giving off it's thermal radiation but beyond that you can see through it pretty well, the closer and hotter the object on the other side the clearer the image through it, (this also works with very thin clothing). The downside is if your trying to walk you could easily not notice the plastic sheeting. Also a fun fact you can see hot/cold gasses like your dry ice test where you see the slight whisps of the cool air so you'll know who let it rip if you happen to be watching with the thermal. Last but not least despite not seeing through glass (it can't because as you mentioned it sees the surface temperature) if you were to touch the glass on the side away from the thermal for long enough your handprint would eventually bleed through and could be detected, for those who don't understand it's because of heat transfer that warms up the glas in that spot essentially warming it enough that the other side gets warm enough to detect. Beyond that the points you talked about are spot on just figured I would add some info that I had wondered about for many years (until I dropped the multiple grand it cost to purchase one and find out). If this comment gets idk 20 likes I will post a video showing more fun things utilizing a 720p thermal microblometer (the thermal sensing chip). Oh and one last fun fact, the original thermal imaging systems required liquid nitrogen to operate and were upwards of $80,000.00 that is until the microblometer was invented as the chip itself is in a vacuum allowing it to detect the thermal inferred radiation / aka heat.

What will happen if we write a information down in a piece of paper can we see the information in the thermal image??

[@Maxx__________]

I notice that pilot videos with UAPs go dark around the object once they switch to thermal. Does this mean it's really cold?

[@karolinahagegard]

I want to know if you can catch CO2 with an IR camera but not, say, NO2, because CO2 is a greenhouse gas (thus can absorb and reemit IR) but NO2 isn't? And what about hot CO2 and NO2? Do they look different at the same temperature because of the greenhouse gas property?

[@perdedor3571]

CO2 you can definitely see if you have the correct camera.

[@mrkiky]

You should have shown the black nylon trick as well.

[@parranoya100]

[@jwserge]

Can not understand: If a metal can reflects the thermal emission back inside, and the thermal camera can not see any difference, why then the outer surfaces of the cans are HOT and COLD when touching them? If its surface is hot then it should illuminate like the phisical Black Body. So, there is some gap in my understanding. The tape attached to the cans - illuminates IR, but the hot metall surface does not illuminates IR - why? Incandescent bulb when red-hot illuminates in visible red even yellow color and we see it bare eyes, but why the thermal camers can not see InfraRed when it is warm, not hot??? If we heat up the can to Red-hot it will be red illuminating, isn't it?

[@muhammadmusharrafkhansyal3160]

can you explain how a mirror would react to thermal imaging will it show a thermal image in reflection will it be just like the containers nothing or like the glass nothing

[@IAM_GhosT1]

A mirror will react just like it does normally, except it will be a thermal reflection instead of regular light. When I first got my thermal unit I scared the H*** our of myself when I was looking around my friends house and didn't know he had a wall mirror, I turned to face it in a pitch black room and to my surprise there was this person standing right were I was. Obviously it was just my reflection but this was before I knew about far inferred light radiation.

It would be nice if you guys did a review on the Sparkfun Lepton Flir break out board diy thermal imager. Low pixels at distance may be cool to compare.

[@Roswellflighttestcrew1947]

+Hoverbot1TV We've been talking to FLIR for a while about flying a Lepton imager, to see whether or not it would be safe and/or practical to use one for FPV, owing to the extremely low resolution. It's something that we're looking at doing at some point in the future, although they (understandably) want to be cautious about suggesting, even by implication, that a piece of their technology be utilized for a task that it isn't well suited for -- especially something like controlling a drone, where there are legitimate safety concerns. However, it is definitely something that is being discussed. Stay tuned.

No, the water will show up usually colder but also act as a reflective surface, you will get a dark reflection as it will reflect space / cold.

[@resart5445]

Why dosnt the lence of the camera block infrared light

[@Roswellflighttestcrew1947]

Great question! The answer is: the lens isn't made of glass -- it's made of precision-ground Germanium (Atomic number 32, "Ge" on the periodic table). It was discovered in 1885 in a silver mine in Germany (no surprise there). The fact that Germanium, instead of glass, has to be used to produce the lenses for thermal cameras is one of the many reasons they are so expensive.

[@adalovelace95]

Because lenses for thermal cameras are made from Germanium.

[@Roswellflighttestcrew1947]

+Jason Parker We didn't cover this fact in this video, but the surface of water -- like a lake or a river -- actually acts like a mirror when you point a thermal imaging camera at it: you can even see reflections of the clouds in the sky overhead, for example. So, yes, H20 is a very effective barrier to thermal imaging. Thanks for watching!

Yes, if there is enough thermal contrast to allow you to recognize the shape of a human body. Also transpiration cools the body (vaporization) which will make humans appear colder in hot ambient. Themral Imaging does not care about daylight very much.

[@DANGJOS]

It's not just the reflection of the thermal light. Metals (if they're not oxidized) have very low emissivity, which means they emit very little thermal light. So whether what's inside is hot or cool, it doesn't show up on the camera.
