| 摘 要： | 本文通过推导高斯光束照明的毛玻璃产生的散斑的互相关函数，得出此光源的曲率中心经光学系统的成像面为激光动态散斑的纯沸腾面。由此给出确定高斯光束曲率中心位置的方法。

| Abstract: | In this paper,the cross correlation function of the intensity of laser speckles produced by a Gassian beam illuminating a ground glass is deduced.It is proposed that the imaging plane of the curvature center is the pure boiling plane.So a method is given to locate the curvature center of Gaussian beam. |
