| 摘 要： | 本文从理论上对球面波照明弱位相光栅时的自成像现象进行了研究，发现当相对位相分布（x）＜＜1弧度时，位相光栅也存在自成像现象。

| Abstract: | In this paper,a discussion is held on the self-images of weak phase grating,illuminated by spherical waves. It has been found that self-image phenomenon exists,too,with the phase grating when the relative phase distribution is much smaller than one radian. |
