CdF2:Ga crystal application for dynamic joint transform correlator

Dynamical holographic joint transform correlator that uses cadmium fluoride crystal with gallium bistable impurity centers to generate real-time matched filters is proposed. Optical scheme features and the correlator performance are presented. Output correlation signals of object discrimination both experimentally obtained and theoretically calculated are demonstrated. Industrial object recognition illustrates possible practical application of the correlator proposed. The article is published in the original.
