摘　　要：本文研究了部分相干光离焦像面散斑的运动规律.激光离焦散斑是其特例.讨论了制约离焦量的因素,并对其实验技术进行了探讨和验证.In this paper, the moving law of the partially coherent speckle is studied on the defooused image plane. Itsparticular example is the laser defooused speckle. The factors of dominating the defocused amount are discussed and the exprimental technique is investigated.
