一种成倒像投影关系的非相干光相关器

A New Scheme for Incoherent Correlator With Inverse Image Projection

提出了一种新型成倒像投影关系的非相干光相关器,这种相关器具有便于校准输出平面位置的优点。使用傅里叶光学理论对这种相关器相关输出图样进行了仿真实验。结果表明,这种相关器和其他非相干光相关器的相关输出质量相同。对于相关峰展宽的仿真分析表明,虽然这种相关器具有低通特性,它的适用范围仍然比较广泛。

A new scheme for incoherent correlator, with an inverse image projection procedure is proposed which can be calibrated easily. The correlation output distribution is simulated with Fourier optics theory, and the results show that the performance of the new scheme s as good as other schemes of incoherent correlators. The simulation for correlation peak stretch shows that it can be applied widely, even with low-pass.
