Abstract

The compact scheme of the incoherent holographic correlator with two-coordinate acoustooptic deflector (AOD) for input of recognized images is presented. Because AOD forms an input image as a sequence of dynamic diffraction gratings, it allows to put a holographic filter directly in the place where AOD is situated. The experimental setups of the correlator with holographic memory and monochromatic illumination are described. Experimental results on recognition of test objects with two different illumination sources are presented. The correlation signals for setups with He-Ne laser and semiconductor laser are coincide within the limits of experimental errors. The result obtained show that both experimental setups of the incoherent holographic correlator provide real-time recognition of input images formed by two-coordinate acoustooptic deflector.
