夫琅和费衍射区内的Talbot效应

TALBOT EFFECT IN FRAUNHOFER DIFFRACTION ZONE

本文对球面波照明一维振幅型光栅时，在夫琅和费衍射区内的Ｔａｌｂｏｔ自成像进行了研究。得到了其成像条件，并与菲涅尔衍射区内的成像条件作了比较。

In this paper,Talbot self-imagings of amplitude grating illuminated by spherical waveare discussed in Fraunhofer diffraction zone. The imaging condition has been found and isdrawn into a comparison with the in Fresnel diffraction zone.
