I am an photographer and archaeologist. In archaeology business , thermal sensing is done with satellites or drones. To do that , you have to see the heat or lets say infrared. Modern digital cameras do the opposite , their sensors are ultimately sensitive to heat image or infrared image and they cut this sensivity with factory installed ccd or cmos sensor filters.

But some does hack remove that filter and camera repairman can remove this small thin glass filter placed in front of sensor.

When you remove it camera starts to see the heat as picture. All the woods , undersoil archaeological stone artifacts starts to appear on image.

May be someone can do this trick to sense the heat wave or thermals in air.

Someone can do it for telephone camera and telephone changes the small value changes with big color changes and even telephone can alert the boomerang thrower with sounds

continue to post: AFTER BELOW DISCUSSIONS.

Its been proved air has no infrared signature and camera cant see the hot air but it can be done with new idea.

If the camera cant see the hot air , it can still see the land cooled or heated.

Thermal air dislocation can be traced from land heat difference.

No, that's wrong. These sensors are sensitive for visible light. For IR you need sensors operating at IR wavelegths.

That also doesn't work. Air is for IR as transparent as for visible light. So when you aim the thermographic camera down to the ground it shows you the "heat" of the ground surface and not of the air between ground and sensor. And if you aim it up into sky you only get a homogeneously "picture" of ONE low temperature or the spot of the hot sun.

What you need is this:

if you have little money left...

You dont have any idea what you are talking. CCD and CMOS sensors are extremelly ultraviolet and infrared sensitive.

I think you are not understanding whatever you are reading. Go to a physiciatry department.

if Your thermal imagers cant see the thermal , its not because they cant see but its because they are designed to not see the air heat difference.

If you setup your telephone imager fake color program , you can see the heat picture in air , if you do it stereo , you can see in 3d.

okay you specialist, then you are of course able to show us thermal pictures of mixed tempered air...

Think about that:
when you are convinced that the sensor of telephone are sensitive for UV, IR and obvious everything between, what do you think how intense it will seperate only thermal radiation to picture? Or will the visible light overflow thermal information?

Zitat:
if Your thermal imagers cant see the thermal , its not because they cant see but its because they are designed to not see the air heat difference
that's not logical. I own a Testo 875 thermal camera and have joined a training course for it. How should they designed not to see heated air but warm surfaces? I can tell you: the thermal emisson rate of air is zero. That's not a design, it's a physical fact.
