Paper Abstract

Angularly multiplexed volume holography is considered for use in optical memory systems because of its compactness, capacity, fast parallel access, and associative readout capability. The associative nature makes holographic memories especially attractive to database applications. We define three characteristics, recall, precision, and fallout, and propose a figure of merit to measure the accuracy of associative recall and evaluate the performance of holographic memory systems with different types of data. The effect of a post-processing technique on the quality of the system's response is presented as well. This technique can significantly improve the performance of associative searches involving analog data.
