一维光栅的阿贝成像原理及空间滤波的研究

Exploration onAbbe's Theory of Image with One-dimensional Grating and Spatial Filtering

主要探讨了一维矩形光栅的阿贝成像原理及空间滤波问题的研究,分别从实验上对一维光栅在阿贝成像原理实验进行各种空间滤波,从理论上讨论了一维光栅的占空比以及各级衍射波对成像结果的影响情况。实验与理论结果完全符合,有利于深入理解阿贝成像原理及空间滤波。

We mainly discussed the exploration of Abbe' s theory of image with one-dimensional grating and spatial filtering. We conducted series experiments on spatial filtering with one-dimensional grating, and discussed that how the duty cycle of the grating and the diffraction of each order would affect the result of imaging. The experimental result completely accords with the theoretical one, which helps the further comprehension of Abbe's theory of image and spatial filtering.
