摘要
用一种近解析的方法研究厄米-高斯光束通过内含硬边光阑的近轴ABCD光学系统后的聚焦特性:焦移和焦开关.数值计算表明使用这种近解析法所得结果与对Collins公式直接作数值积分的结果符合甚好,且计算速度大大提高.
With an approximate analysis, we study the focus qualities of the H-G beams which passing through a paraxial ABCD optical system with hard-edge aperture: focal shift and focal switch.It is shown that the results obtained by the approximate analysis have better consistences than by straightforward integral of the Collins formula and the working speed is highly improved.
