Paper Abstract

As a result of optical experiments, it is established that the controlled variation of a recognition sensitivity at the comparison of the input and reference objects can be realized, while solving the recognition task within the method of synthesized phase objects,1 as distinct from the standard approach. We have obtained and analyzed the results of the recognition for a collection of objects with the use a joint Fourier-transform correlator. For each of the objects, we studied the character of the signal amplitude decrease depending on the growth of distortions in the object structure. We show that it is possible to obtain a family of cross-correlation curves that decrease differently within the method of synthesized phase objects, rather than a single curve. This allows one to vary the sensitivity of the correlator in the process of recognition.
