对Talbot自成像和几何成像关系的分析

Relationship Between Talbot Effect and Geometrical Imaging

针对Talbot自成像与几何光学成像毫无关系的传统观点,本文提出了一种用于几何光学成像原理和物理光学成像原理对光栅成像进行对比分析的方法,发现在某一特殊的Talbot成像距离处,光栅自成像和几何成像有相同的成像规律,当光源为单色光照射时可以认为光栅的几何成像实际上是某一个特殊位置的Talbot像.

According to traditional view that there is no relation between the Talbot imaging and geometric imaging and based on the geometric optics imaging rule and physics imaging rule,a new method to analyse the grating imaging was introduced . It was found that when m = 0, the Talbot imaging has the same imaging rule with geometric optics imaging. A conclusion is presented that the geometry optics imaging of grating is a certain Talbot imaging when coneolorous and parallel light irradiate the grating.
