Hartmann-Shack波前传感器两种子孔径布局探测性能比较
-
摘要: 通过自适应光学中的Zernike模式波前重构算法进行计算机仿真计算，对Hartmann-Shack 波前传感器中针对环形波前设计的两种微阵列透镜子孔径布局的探测性能进行了比较。还就两种子孔径布局的排布方式、完全探测信息能力以及容纳光强起伏能力进行了比较。结果表明，环形布局在探测性能上与方形布局相近，在完全探测信息、容纳光强起伏等方面明显优于方形布局，是一种适用于环形波前探测的子孔径布局方式。Abstract: By simulating wave-front reconstruction with Zernike polynomials, the comparison of detecting performance for the annular beam between two configurations of lens array, which is a key element in Hartmann-Shack wave-front sensor, is presented in this paper. In addition, the matching ability for the annular beam and adaptive capability for the un-uniform intensity are compared. Results show that the annular configuration is better than the square one.
