摘要: 本文首次用矩阵光学理论,结合光栅衍射相于条件,推导出光栅自成像条件,用像的位移叠加观点解释了光栅自成像现象,并分别讨论在球面单色波和平面单色波照明下自成像的特点。Abstract: Based on the optical matrix theory and diffraction condition of the grating, the self-imaging formula of the grating is derived. The self-imaging phenomenon of the grating is simply explained as the result of the imaging shifting and overlaping. The properties of the self-imaging of the grating illuminated by spherical and parallel monochromatic waves are discussed respectively.
