剪切干涉仪与Hartmann的波前复原比较
-
摘要: 对横向剪切干涉仪和Hartmann波前传感器的波前探测和复原进行了类比推导和仿真计算。结果表明，在相同输入波前，相同探测面元，相同拟合函数及阶数的情况下，横向剪切干涉仪的波前复原能力比Hartmann波前传感器强。主要原因是前者对波前的间接采样所包含的波前信息大于后者，并且前者比较容易增大对波前的采样。

Abstract: The detection and reconstruction of wavefront by Lateral Shear Interferometer (LSI) and Hartmann Wavefront Sensor (HWS) have been deduced analogically and simulated numerically. It is shown that the ability of wavefront reconstruction of LSI is better than HWS, for the indirect sampling information of wavefront with LSI is more than HWS. And to increase sampling, LSI is easier than HWS. -
