Method for replacing objects in 4F correlator: testing
The method of pattern recognition based on replacement of object images incoming to the correlator by object-dependent synthesized phase objects calculated using the iterative Fourier-transform algorithm was developed by us earlier. In this work, we performed experimental testing the above method by...

The method of pattern recognition based on replacement of object images incoming to the correlator by object-dependent synthesized phase objects calculated using the iterative Fourier-transform algorithm was developed by us earlier. In this work, we performed experimental testing the above method by using an optical-digital 4F-correlator. Synthesized phase objects were inputed into the correlator through the spatial light modulator LC2002. Holographic matched filters were recorded using self-developing photopolymers PPC-488. For two test objects, we obtained unified (δ-like) correlation signals with the signal-to-noise ratio reaching 24 dB, while the diffraction efficiency of these filters was up to 30%. |
