相干光学的理论研究最早可追溯到1893年阿贝所完成的显微镜成象理论,但是,由于当时使用的光源都是非相干的,应用范围受到很大限制,因而在很长时间内,相干光学技术几乎没有什么大的进展。六十年代由于激光器的出现,人们获得了高亮度的相干光源,古老的光学领域就此别开生面、以光学信息处理为内容的研究课题已跨出了光学的范围而迈入许 The theory of coherent optics can be traced back to the microscope imaging theory first completed by Abbe in 1893. However, since the light sources used at that time were incoherent, the application range was greatly limited. Therefore, for a long time, coherent optics Almost no big progress. In the 1960s, with the advent of lasers, people obtained high-intensity coherent light sources, and the ancient optics field was quite unique. The research subject of optical information processing has taken the optical reach and entered the optical field
