利用Mach-Zehnder干涉仪实现黑白图象密度假彩色编码

Black-white image density falsecolour encoding achieved by Mach-zehnder interferometer

本文提出一种黑白图象密度假彩色编码的新方法。它以Mach-Zehnder干涉仪作为输入装置,并用两个光栅分别对位相型输入图象和参考白光束加以调制,然后在频率域施行小孔滤波,所获得的编码图象其颜色与密度的对应关系连续可调。

In this paper, a new method for density falsecolour encoding of a black-white imago is presented. The Mach-Zehnder interferometer is used as the input divice. A phase input image and a reference white beam are spatially modulated by using two gratings respectively, then the aperture filtering is taken in the frequency domain,.The encoding density falsecolour image has been obtained which dependence betweer, colour and density can be adjusted continuously.
