An associative-memory model and its optical implementation with grating structures are presented. The transmission function of each pixel of the content-addressable memory is calculated by use of scalar diffraction theory. The filter of the calculated transmission function can be fabricated with computer-generated holography and a multiexposure holographic technique. The proposed approach is found useful in terms of storage and the simple thresholding at the number of on-state pixels in the input.
