摘要 为了从实验上分析和验证H-S传感器测量M2因子方法,对使用双曲线拟合法测量M2因子和H-S传感器测量M2因子做了详细的实验研究,且对实验结果、实验误差进行了比较与分析。研究表明:当H-S波前传感器透镜组足够多,重构误差较小,选取合适的泽尼克多项式阶数时,H-S波前传感器一次测量法得到的光束的M2因子与传统方法测得的M2因子值基本相当。与双曲线拟合法相比,H-S传感器法适用范围小,但是当满足测量条件时,H-S传感器法更便捷。 The measurement methods of M2 factor using hyperbolic fit and Hartmann-Shack sensor are studied experimentally.The results and experimental errors are compared and analyzed.It is shown that the measured M2 factor is approximately consistent using the two methods when the Hartmann-Shack wavefront sensor contains enough lenslet array,the reconstruction error is small and the orders of the Zernike polynomial is suitably chosen.Compared with the method using hyperbolic fit,the methods using Hartmann-Shack sensor has small scope of application.However,the method using Hartmann-Shack sensor is more simple when it contents the working condition.
