Paper Abstract

One of the most effective ways of correlation analysis of images is processing of their Fourier spectra with the help of holografics filter (Van der Lugt filter for example). Practical realisation of such a correlator for high-informative ( >103x103 elements ) image is a non-trivial scientific-engineering problem, which is ever more complicated by the usage of many (~101) filters being written down consequently in each channel for example with the help of multiplicator, having two crossed phase gratings, placed just after the processing image.
