摘要
本文根据Ｃｏｌｉｎｓ衍射积分公式分析了高斯光束通过光阑——透镜分离系统后的焦移情况，得到在不同的分离状况下，其焦移可能反向或被消除。
In this paper,the focal shift for a Gaussian beam passing through an aperture lens separated system is studied by using the Collins diffraction integral formula.It predicts that the focal shift may be reversed or eliminated depending on the case of separation.Its two limiting cases are also analysed here.
