Functional properties of three-dimensional holograms and their application

Filtering properties of three-dimensional holograms are experimentally studied. Comparative analysis of three-dimensional and thin-layer holograms is given. The dependence of the output signal from a three-dimensional holographic filter on its structure and parameters of the input signal is investigated. A physical method is proposed for design of a holographic filter which performs linear integral transformations of general kind over two-dimensional signals.
