My background is neither astronomy nor instrumentation but rather image analysis. Hence, I am not going to describe new equipment nor new astronomical findings, but rather some difficulties which have arisen in other fields where images must be interpreted and manipulated, and which are sure to arise in astronomy as well.

I shall limit my attention to problems arising from coherence of the radiation in the analysing instrument and attempt to isolate their source and give guidance on how to recognize them and avoid them.
