Abstract

We describe two novel types of optical associative memories and related experiments. A method to retrieve stored images in a hologram with the brightness of each retrieved image proportional to the overlap integral of that stored image and the input image is described. By using the bistable oscillator as a thresholding device, we demonstrate the associative features of the memories. Associative memories based on message bearing optical modes in phase conjugate resonators are also discussed.
