We are a team of astronomers having the goal of doing very high precision (0.1% in bands) photometry with big optical telescopes. Optical telescope accuracy on earth are limited by clouds, especially thin clouds that are difficults to detect. One solution could be the use of an infrared camera to make a map of clouds optical depth in telescope field of view. We tried an uncooled LWIR Camera (FLIR) . But it is very difficult. Perhaps a MWIR would have been a better choice according what you say on IR camera accuracy. Presently our goal is to measure radiances, not temperatures. From measured IR cloud radiance, one can predict the optical attenuation.

Thank you for very much informative video. Knowing that you have expert knowledge in field of IR cameras, is it possible to use very thick germanium glass to shield flir lepton infrared camera module's lenses from water, dust, high/low temperatures and nearby explosions? Or maybe there are other ways to protect IR camera's lenses which you can share? Unfortunately i cannot use usual reinforced glass for infrared cameras because usual glass is not transparent for IR spectrum.

Yes, many thermal sensors, particularly in high-performance infrared cameras, are cooled to enhance their sensitivity and accuracy.

@@TobyCatVA i just ask AI and this is the response. Thermal cameras can detect heat signatures, which means they can indeed see people and warm objects through certain materials, but this doesn't extend to seeing through all types of walls and windows: - **Windows:** Typically, thermal cameras can see through regular glass windows quite effectively because glass is transparent to infrared radiation. However, if the window is coated with certain materials or films designed to block infrared, the camera's effectiveness might be reduced. - **Walls:** - **Thin or Lightweight Materials:** They might detect heat signatures through very thin walls or materials like plywood or some types of siding, especially if there's a significant temperature difference. - **Thick or Dense Materials:** For standard building materials like brick, concrete, or thick wood, thermal cameras will not see through them. These materials block or absorb infrared radiation, preventing it from passing through. - **Gaps and Insulation:** Thermal cameras can sometimes detect anomalies where heat might escape, like around windows, doors, or through poor insulation, but this isn't "seeing through" the wall so much as detecting heat loss patterns. - **Limitations:** - The thickness, density, and composition of the material significantly affect penetration. - The temperature difference between the object/person and the background is crucial. A greater difference makes detection more likely. - Interference from other heat sources outside the wall can confound readings. In summary, while thermal cameras are excellent for detecting heat differences and can sometimes give you information about what's on the other side of certain barriers, they are not capable of seeing detailed images or clear outlines of objects or people through solid, dense walls like those in most homes or buildings. They're more about detecting heat patterns and anomalies rather than providing X-ray vision.

Does this camera store a stream of RJPEG images as a form of a video? The goal is to get the thermal data naturally from the video. From my experience a standard .mp4 format video cannot store thermal data, unless there's a min/max temperature value for each frame within the captions.

Can it be used in both wild life and real workspace settings over urban home theatre environments ? If so then how does it differentiate between human and animal gaits energy signature ?
@SierraOlympiaАй бұрын
Yes, our infrared technology can be used in both wildlife and in urban environments. Infrared cameras detect heat signatures from any object or being that emits thermal energy, making them versatile across various applications. To differentiate between human and animal gaits or thermal signatures, the camera relies on patterns of movement, size, and temperature distribution. Humans and animals emit distinct thermal patterns based on their body structure and movement.

Hmmm, while this is very impressive demonstration on its own, one can't help but wonder about how much operational relevance it actually has. Sure the drone was "detected" 4km out. But only as a tiny blurry blob, and with the system staring directly at it. The website states the camera system's FOV is "8.8º-0.6º", so to get solid coverage of the entire horizon at that distance would require... a lot of these! I didn't see a price listed on the site, but I can't imagine that'd be cheap. Furthermore, even with the most advanced AI assistance, it must be incredibly difficult to identify a threat in all the noise of moving background, birds, bugs, turbulence, etc. So even having the drone in-frame wouldn't guarantee detection. The fact the video editor decided to use a circle to highlight the drone in these clips speaks to that. All in all, not really sure what this test proves in regards to dronetection. The Ventus could certainly be useful in conjunction with some sort of hybrid integrated sensor network, but that's not what was discussed above. What'd be fun and would prove a lot more is to zip-tie a paperweight to the bottom of a Mavic and see how close a pilot could get to directly over the observer before the drone was spotted. As the pilot and spotter got more experience and switched off, it'd get progressively more challenging for both as the pilot tried different tricks and the spotter got better at spotting. That'd get some actually relevant numbers.

Is the sensor saturated by fire this easily? Do you offer a low gain option or attenuation filters to get extended range?
@SierraOlympiaАй бұрын
Great question! Infrared sensors can become saturated when exposed to extremely high temperatures, such as fire, but we offer solutions to manage this. Many of our cameras include low-gain settings that help prevent saturation and extend the dynamic range of the sensor. These features allow the camera to capture more detail in high-temperature environments, making them ideal for applications like firefighting, industrial inspections, and monitoring intense heat sources.
