| 摘 要： | 根据Collins公式,导出了球而波经带有后继光学系统的硬边光阑衍射的焦移公式,并给出了等效的变换矩阵。光阑的作用可等效为一个具有可变焦距的“薄透镜”。

| Abstract: | Based on Collins formula,the focal shift formula of a hard aperture followed by a complicated opticalsystem is derived under spherical waves incidence. An equivalent transfor matrix is given. It can be concluded that anaperture is equivalent to a "thin len" with a variable focal length. |
