| 摘 要： | 本文提出一种一次性提取两幅图像相同或相异部分信息的新方法。两束受待处理图像调制的单色光波相干叠加形成全息图,再现后即可得到两幅图像的相同或相异部分的信息。该提取方法利用了图像相乘,并考虑到半波损失效应,光路简单,调节容易。若利用光致折变晶体可实现实时在线提取。给出了实验结果。

| Abstract: | A new method to extract identical and different parts of two images is proposed. Two monchromatic beams modified by the processed images interfere to form a hologram from which the identical or different parts are reconstructed. In our method, multiplication of images and the Stokes principle are applied. The optical setup is simple and easy to align. Real-time processing can be achieved if photorefractive material is used. Experimental results are presented. |
