Abstract

Theoretical expressions and convergence conditions are developed here for the output of a feedback holographic associative memory. It is shown that a feedback holographic associative memory becomes a pinhole holographic associative memory under certain conditions, and thus is a generalization of the pinhole holographic associative memory. The crosstalk in the output of a feedback holographic associative memory can also be removed by a threshold device or controlled by the overall optical efficiency of the memory. A simulation is provided to verify the theoretical results shown here. Using the theoretical results and simulation verification, a feedback holographic associative memory can be designed efficiently. In addition, if a threshold device is used, optical elements with high optical efficiency can be used in a feedback holographic associative memory.
