| Abstract: | The diffracton of the grating is analyzed by the theory of the Fresnel diffraction, and the general formula of the diffraction intensity of the grating in Fresnel diffraction region is obtained. Through lots of the numerical calculations, it is found that the influence of size of the grating on the Tabot effect at a certain Talbot distance is obvious. For a grating with the same size, the further the Talbot distance is, the severer the influence of size of the grating on the Talbot image is. The physical expression for this influence on the diffraction intensity at the Talbot distances is performed too. |
