提出了一种基于铁电体液晶空间光调制器的多通道光学相关器，它利用了由电寻址空间光调制器的方格状结构所产生的高级衍射现象，同时给出了初步的实验结果．
A multi-channel optical correlator based on a ferroelectric liquid crystal spatial light modulator is proposed, which takes advantage of the high-order diffraction phenomena produced by the grid-like structure of an electrically addressed spatial light modulator and gives a preliminary experiment result.
