通过Zernike模式波前重构算法进行计算机仿真计算,对扇形子孔径布局的Hartmann-Shack波前传感器探测性能进行仿真研究,对比分析了方形子孔径布局Hartmann-Shack波前传感器的探测性能。结果表明,扇形子孔径布局是一种有效的Hartmann-Shack波前传感器的布局方式,在低子孔径密度且孔径数目差异不多的条件下,比方形孔径布局探测精度更高。

By simulating wavefront reconstruction with Zernike polynomials, the performance of the sector lens array configuration in H-S wavefront sensor was tested. Compared with square lens array configuration in H-S wavefront sensor, the sector lens array configuration in H-S wavefront sensor has better performance when the number of the array lens of the two configurations is commensurate. However, the simulating of the wavefront which was measured by the interferometer shows the two H-S wavefront sensors comparatively reconstructed the original wavefront.
