利用互补光栅编码实现光学图像的微分
Optical image differentiation by compensative grating encoding
摘要
Abstract
A new method for optical image differentiation is presented. By means of encoding the differential information of images by grating encoding, low-pass filtering and polarization filtering, the differential results of the optical image are obtained by decoding in a common with white-light optical system. This method is simple and easy to operate, it has other merits of white-light processors.
