I worked on such a device a few years ago.  We used an Eikonix Image
Digitizer to digitize autoradiographs, 512 by 512 by 8 bits deep.
This device uses a 512-element linear CCD array that steps mechanically
across the projected image.  We had a fancy light source set up
to illuminate transparencies.

A friend digitizes microscope images from a video signal.  He can
digitize movies in real time, until he runs out of memory to store
the images.  Only five or six bits deep, though.
