Relationship Between Talbot Effect and Geometrical Imaging
对Talbot自成像和几何成像关系的分析

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 concolorous and parallel light irradiate the grating.
