Demonstration of an all-optical associative holographic memory
Amnon Yariv, Sze-Keung Kwong, Kazuo Kyuma · Applied Physics Letters · 1986
We describe a new type of associative holographic memory and some related results. The memory can retrieve overlapping images which are stored in a volume hologram. The storage and retrieval of more than one image is demonstrated for the first time. The important role of thresholding in assuring ‘‘clean’’ retrieval is demonstrated.
