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.

Thank you.
My friend ordered on Aliexpress high resolution mini usb thermal camera for smartphone
and we have tested it to work fine for electronics due to its resolution and a very small size ( width of usb cable connector)
at $300
