Abstract
The incoherent holographic correlator for image recognition without edge-enhancement preprocessing is described. The method of forming positive and negative parts of impulse response of holographic filter that provides a peak-to- clutter ratio and signal spatial localization as in the case of recognition of edge-enhanced images is discussed. Experimental scheme of investigated bipolar holographic correlator with spatially incoherent monochromatic illumination and the method of forming bipolar reference pattern are described. Also the results on recognition of test non-edge-enhanced images by using the developed holographic filters are presented.
