    My first scanner employed a white florescent light source with the
    sensor array, it had good depth of field and made sharp copies of
    populated pcbs .
    My new scanner lights with rgb leds and copies pictures ok but has no
    depth of field ie pcb is blurred.
    Where can I find a good technical description and analysis of the
    advantages and disadvantages of the various technologies.
    Another example of the absence of technical information for the public.
