Single point thermal imaging camera made of infrared thermometer
Let me know your opinion and experience
since high resolution thermal imaging cameras are still expensive
so I plan to build a single point thermal imaging camera supported by mosaics scanning mechanics
to get high resolution thermal imaging
thank you

A single-point sensor will probably be big so have poor spatial
resolution. And scanning will be very slow.
Amazon has 256x192 thermal imager cameras, all done, starting around
$250. They probably don't focus close enough for electronics but that
could be fudged. Some software image enhancement might be possible.
We have two FLIRs. One was very expensive and has a huge
adjustable-focus germanium lens. It's fabulous for scoping
electronics.
Lens:

Dual NPN transistor, obviously not monolithic:

PCB inner-plane short:

(A bunch of amps burned that away.)
Our other IR imager was a gift from FLIR, a smaller fixed-focus thing,
pretty much useless for electronics:

I'd like to have a small handheld imager, but it needs to focus up
close, which most don't do.

We have a FLIR-1, which attaches to a smartphone and works pretty well
for troubleshooting boards. It tries to get better resolution by
combining the lowish-resolution IR image with a strongly edge-enhanced
image from the phone camera, and then dorks the alignment to reduce the parallax effect.
It was about $400 a year or two ago.

This one is interesing:

it seems to have a much higher frame rate than my Flir E4 (hacked into
an E8) which is limited to 9 frames per second I think to avoid being
subject to export controls.

How close can it focus? Enough to resolve small parts on a board?
