摘 要: 改进了阿贝成像原理和空间滤波实验.将物平面置于傅里叶变换透镜的前焦面,采用扩束光照明,在光源的共轭像面上测量频谱分布、改造频谱等,可以获得更好的实验效果,同时简化了光路. When object plane is placed at the front focal plane of lens, the Fourier frequency spectrum on the image plane can be measured and changed under expanded illumination. As a result, the optical system of Abbe-Poter principle of image formation and spatial filtering experiment is simplified, and better experimental result is ohtained.
