I wonder if something as simple as a USB web camera could be used?  If
all you want to do is measure the density range - the low resolution of
these cameras would not be an issue.  I know most of these allow you to
capture a still image - It would just be a matter of finding the
appropriate software - I assume you use a Mac Sam - You may be able to
use ImageMagik to invert a folder full of images.
