Abstract

Pattern recognition via optical correlation generally requires an incoherent-to-coherent input image converter and benefits from edge enhancement of the input image. We have created a photoaddressed nematic liquid crystal differentiating spatial light modulator that fulfills both these functions. Developments in photoaddressing are discussed, and experimental results on edge enhancement are presented.

摘要

通过光学相关进行模式识别通常需要一个非相干到相干的输入图像转换器，并且受益于输入图像的边缘增强。我们已经创建了一种光寻址向列型液晶微分空间光调制器，它实现了这两种功能。讨论了光寻址方面的进展，并给出了边缘增强的实验结果。
