Ｈａｒｔｍａｎｎ－Ｓｈａｃｋ波前传感器是自适应光学中几种重要的波前传感器之一。本文利用Ｆｏｕｒｉｅｒ光学方法分析研究了Ｈａｒｔｍａｎｎ－Ｓｈａｃｋ波前传感器的原理，导出了辐照度分布质心与子孔径波前倾斜的解析表达式，说明了辐照度分布质心及其算法的物理意义，总结了该传感器的若干重要特点。
The Hartmann-Shack wavefront sensor is one of several important wavefront sensors in adaptive optics. In this paper, Fourier optical analysis of the Hartmann-Shack wavefront sensor principle, derived the centroid of the irradiance distribution and subaperture wavefront tilt analytical expression of the irradiance distribution centroid and the physical meaning of the algorithm, concluded Some important features of the sensor.
