As a first off, trying using the Gerchburg/Gerchburg-Saxton routine, this is a very simple algorithm to program and use, but can produce good results. If you can find a copy have a look at a book entitled Deconvolution by P Jansson. The best method (if there is one!) is the maximum entropy method, there are free downloads of software using this method available somewhere on the web. However, I have yet to find one that is suitable for easy insertion into an exsiting program. Perhaps if you manage to find one, you can send me a copy as I am currently looking for this particular form of nirvana.
