摘要

在入射光束的孔径受限制的情况下

利用衍射光学元件来增加激光束的焦深。首先确定光阑孔径的大小、然后利用Y-G算法

在已知入射和出射光波函数的条件下

计算出衍射光学元件的位相分布。计算结果表明焦深可以比未用衍射光学元件时增加一半或更多。

Abstract

Placing a diffractive optical element(DOE) on the incident laser beam to improve the depth of focus

the DOE'S aperture is variable.When the radius of the aperture changes

the depth of focus changes too.The DOE's phase distribution can be determined by the input beams's and the output beam's amplitude distributions with a Y G algorithm.The results of computing show that the depth of focus is much larger than that of without DOE.
