Abstract

The nonlinearities of photorefractive materials such as Fe:LiNbO3, BSO, BGO,… are used to filter the Fourier spectrum of an object. Image processing techniques, such as contrast inversion or contrast enhancement of amplitude objects, and phase objects visualization are thus obtained with simple optical devices and low power cw lasers.
光学图像处理:光折变材料的空间滤波
利用Fe:LiNbO3、BSO、BGO等光折变材料的非线性特性对物体的傅立叶光谱进行滤波。图像处理技术,如振幅对象的对比度反演或对比度增强,以及相位对象的可视化,因此获得了简单的光学设备和低功率连续波激光器。
