Abstract
Information processing by coherent optical systems, such as optical correlators, spectrum analyzers of two-dimensional signals and others, requires development of recyclable photosensitive media to be used in spatial light modulators and holographic filters. In many cases, the optical processing system as a whole, and its separate elements, are treated in the framework of the theory of linear space-invariant systems [1,2]. Here the notions of the impulse response and transfer function are introduced. It is just these parameters which give a rather complete idea about the information capabilities of the system as a whole and its separate elements.
