Spatially invariant optical-signal filters based on volume holograms
A. E. Krasnov Institute of problems of management of the USSR Academy of Sciences, Moscow
Abstract:
An analysis is made of the physical basis of the processing of coherent optical signals with the aid of volume holograms. The coupled waves approximation is used to obtain a dynamic equation for the propagation of optical signals and of the associated noise in such holograms. An approximation solution of the dynamic equation is used to calculate the response of a volume hologram, recorded with the aid of a coded reference wave, to an arbitrary reconstructing signal. It is shown that such a hologram belongs to a new class of devies for the filtering of coherent optical signals, which are spatially invariant filters of the spatial frequencies. The main types of noise in a volume holographic filter are considered and the real dynamic range of the filter is estimated. An effective method for minimization of the filter noise is proposed.Methods for synthesis of a generalized filter transfer functions are discussed. A diagram is given for relating the main parameters of matched volume holographic filters recorded in the widely used photographic materials by a variety of methods.
