Properties of holographic associative memory prepared by the polarization encoding process.
A new holographic associative memory (HAM) using optical polarization is proposed. Picture elements (pixels) of binary objects are encoded with two mutually perpendicular states of linear polarization, and they are stored in the HAM using a lensless diffuser system. Experimental results of recognizing various inputs are presented. Analytical expressions about the present HAM are derived, and results of computer simulation are also presented.
