利用液晶光阀实现实时图像微分

Real-time Image Differentiation Using a Liquid Crystal Light Valve

提出一种利用液晶光间实时转换特性实现图像微分的方法。仅简单地通过调整液晶光闪的工作电压，使其处于非线性变换态即可完成对图像的实时微分运算。从理论上分析了液晶光阀的非线性转换功能的原理，给出两种方法的实验结果。

A real-time2 D image differentiation using the transforming function of LCLV is presented.The real-time image differentiating is performed with the nonlinear transforming ability of LCLV only by changing its biasing voltage.The nonlinear property of LCLV is explained from its structure and the experimental results of two methods are given.
