摘要

An approach of in-situ measuring the complex response of a scene spatial light modulator which working in differential state was presented by using an image of Ronchi grating substituted for a concrete one. Its principle and testing method have been studied and a typical XGA2L11 spatial light modulator has been characterized. The scene image under complicated background has been edge enhanced by mapping the measurement results, and the correlation results showed that scene spatial modulator with the differential state can increase the SNR and PCE of correlation peak. The way could be wholly applied in Vander Lugt Correlator and has very strong practicability and effectiveness.
