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

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: https://www.dropbox.com/s/uda77g9w66x3u9f/Flir_E45_WA_Lens.JPG?raw=1 Dual NPN transistor, obviously not monolithic: https://www.dropbox.com/s/dd072w1z2gmfpbt/Dual_NPN.jpg?raw=1 PCB inner-plane short: https://www.dropbox.com/s/rxk5dd8i6gr74nq/PCB_Short.jpg?raw=1 (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: https://www.dropbox.com/scl/fi/6qrx4yyy63gxw5jec1rwa/BT3.JPG?rlkey=q9eb551ur73h5qucgyrck9tsi&raw=1 I'd like to have a small handheld imager, but it needs to focus up close, which most don't do.

My friend ordered on Aliexpress high resolution mini usb C thermal camera for a 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

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.
