摘要：

A real-time high efficiency nonlinear joint transform correlator was proposed. In this correlator, a multi-focus hololens was used to produce joint power spectral array so that the areas of the liquid crystal light valve (LCLV) and the output light energy can be used effectively. The LCLV worked in near-saturated state in order to realize nonlinear joint transform correlation. The theoretical analysis and experimental results verified that the optical correlation signal ban be enhanced by this correlator.
