基于二元纯位相匹配滤波的光电混合模式识别

THE OPTO-ELECTRONIC PATTERN RECOGNITION BASED ON BINARY PHASE ONLY MATCHED FILTER

提出一种优化二元纯位相滤波器 ,抑制低频噪声 ,提高自相关峰信噪比的新方法 ,并用于基于电寻址铁电体液晶空间光调制器的匹配滤波可编程光学相关器 。

A new method to optimize the BPOFs was proposed which can reduce the low frequency noise in output plane and improve the SNR of self correlation. By applying it to the programmable matched filtering optical correlator based on electronically addressing ferroelectric liquid crystal spatial light madulator, the opto electronic pattern recognition was realized.
