    Let me know your opinion and experience

    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?
