This was just a small research project intended to demonstrate the
feasibility of the concept.  There array consisted of around 100 by 100
lenslets.  I do not remember what size the lenslets were.  All work stopped
before mating the array to the CCD.  This is sufficiently far from film
scanning that I am not going to make any more replies here.
