METHOD AND DEVICE FOR SIMULTANEOUS DISTINGUISHMENT OF MULTIPLE SHAPES

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for optical analog image processing that make possible small-scale and parallel image processing for distinguishment of multiple images.

SOLUTION: A method and a device that use optical analog image distinguishment for simultaneous and parallel distinguishment of multiple shapes make possible a small-scale and simple procedure of simultaneous and parallel real-time distinguishment of multiple shapes by introducing simple means for creation of object light and reference light on an LCOS screen, thereby shortening the optical path of an optical system for creation of a multiplex matched filter 46 and facilitating creation of the multiplex matched filter 46 with an optical system for acquisition of clear optical diffraction patterns.
