Abstract

In this paper, a photorefractive crystal based all-optical architecture for implementing the fringe-adjusted joint transform correlation (JTC) technique is investigated. The photorefractive JTC technique is fast because it operates in the optical domain and it generates the correlation output in one step. Computer simulation results using real life image sequences are presented to verify the performance of the proposed technique for target detection and tracking purposes.
