    Standoff. Standoff. Standoff. If you want to hide from thermal you need to be behind the camouflage and there needs to be sufficient standoff that your body does jot warm the camouflage up.

      @@LarsLarsen77 No, you will see it on the thermal camera. All of these so called thermal camouflage tests are done with low cost unit's with relatively low resolution and high NETD. If you use an umbrella to shield yourself, the camera will see an umbrella or the outlines of it. Any drone operator or seasoned thermal camera user will draw it's conclusions. Also, thermal cameras in that wavelength can't see through glas, it will act as a mirror. So it's pretty obvious that something is going on. Same with mylar blankets etc. To truly hide from thermal cameras, you will have to hide where you can't be seen. Plain and simple. There is no Harry Potter's cloak that will magically make you dissappear. Not from night vision and not from thermal.

      1. Cats rule the internets. 2. cats have insulating furr of many different lengths, so a first check of contrast spectrum and resolution of the new thermal is easy done with a Mk1 house cat, checking on a tree or neighbours wall with your new binoculars or lens for sharpness and colour bleeding. similar to rendering the standard teapot or furmark for a new GPU or your known hill or supermarket parking lot for acceleration and break tests after the first snow has fallen.

      Or just sample down a sharp video of animals and humans in front of trees etc. As long as the move and the camera is still, it looks like a higher resolution, similar to stationary objects and a moving cameras.

    I did some reading on the topic of thermal camouflage, and I think I have a pretty decent idea of how to do it. You need to have the exterior of the material be close to ambient temperature while isolating it from body heat. If you want to take advantage of different fabrics, you'll need to layer. The interior should contain an IR opaque layer that is a poor thermal conductor - perhaps just a thick fiber, or some sort of IR reflective sandwich. If you use a reflective material, you should probably insulate both sides of it, to negate the visibility of its reflections and isolate the outer layer. The outer layer should probably be some sort of ventilated mesh, maybe separate layers of increasingly thinner mesh. This will adopt ambient temperature because of the ventilation. This actually does provide some insulation, as you can buy netted base layers which perform well in cold climates. It may be interesting to try and find some way to ventilate the interior layer in a convenient direction. With time, anything worn will heat up as you demonstrated, and start to stand out. Also, consider the effect of color; black apparently is the best absorber of IR. However, that doesn't mean the entire outfit should be black, as this would probably silhouette on IR. However, it may provide some signature reduction in areas that are going to be ventilating warm air

    • @CivilDefenseEngineer
      @CivilDefenseEngineer  12 днів тому +3

      You're right-the human body is always going to be giving off heat (if it's alive) so the job of the thermal camo is either to diffuse that heat evenly and slowly, or keep it all in for short periods of time. I also wondered if a cold thermal mass could be carried inside the thermal cloak as a heat sink, or if that would be getting too complicated.

    3:28 it's not the diameter of the lens that dictates its field of view, it's focal length (for given sensor size of course; with larger sensors FOV would be bigger with the same focal length); aperture is irrelevant in that regard.
    Those long wave infrared sensors are not that sensitive (compared to modern visible light ones for example), so they need very "fast" optics, something like f/2 or even faster to work effectively, and if you increase the focal length, lens diameter must also go up for it to still be fast enough, but it's for light gathering purposes and doesn't affect the FOV. You can't just increase the focal length without making the lens bigger, because it would make everything darker, and eventually the sensor would not be able to pick up any useful signal at all.

    • @CivilDefenseEngineer
