I do not see, what do you mean. What cardinal enchancement with
optical side could be done? To change wave lenght, use larger lens or
increase exposure? As a result in any event you'll get a scanned
digital image, what has to be processed by some soft. There are some
things, what cannot be done without proper algorithms. Have you ever
heard about superresolution (or overresolution- I'm not sure about
proper term- English isn't my mother's tongue). It is something like
what you want to get- obtain better resolution than your optical
system allows. I could only repeat- it is not a problem of where the
true edge is, it is a problem of restoration of a transformed image.
This problem requires specific methods. I twice made progs for science
image processing, and in any event I had to use much more complicated
methods than what my client thought.
