摘要
建立了一个小型Ｈａｒｔｍａｎｎ－Ｓｈａｃｋ波前传感器来测量大气扰动特征。通过单子孔径的象移和许多间距不同的子孔径之间的象移差测得的到达角起伏的统计值来计算出Ｆｒｉｅｄ参数ｒ０。本文推导了采用不同孔径参数的实验结果，以及波前斜率的功率谱密度。
We built a small Hartmann-Shack wavefront sensor for measuring atmospheric disturbance characteristics.The Fried parameter ro is calculated through the image moving of single subaperture and the stastatistic values of the arriving angles measured by the image moving differences of many subapertures with different gaps.The experimental results of the different aperture parameters and the power spectral density of wavefront slope are derived in the paper.
