METHOD FOR RECOGNITION OF IMAGES IN OPTICAL-DIGITAL CORRELATORS Russian patent published in 2006 - IPC G02B27/46 G06K9/62 

FIELD: coherent optics, Fourier optics.

SUBSTANCE: method for recognition of images in optical-digital correlators includes procedures for input of amplitude distributions of standard and compared objects into correlator, transformation of these distributions to synthesized phase distributions, receiving correlation between them, registration of received recognition signal and estimation of recognition result, distributions of standard and compared objects, related to arbitrary type objects, are unambiguously matched with phase random distributions Ψ_st(x,y), Ψ(x,y), synthesized from distributions of standard and compared objects and starting phase distribution Ψ_o(x,y), utilized further during recognition in optical-digital correlator instead of real objects.

EFFECT: increased trustworthiness of recognition of images of arbitrary class objects.
