为检测基于五棱镜扫描法的大口径光学系统波前检测法,以口径为513 mm的仿真模拟波面为被测波面进行模拟仿真检测试验,使用通光口径为5 mm的五棱镜对被测波面进行模拟二维扫描检测.根据实验结果拟合出被测波面的二维特性曲线,再利用二维特性曲线对被测波面进行三维拟合,并分析实验中可能存在的误差.实验结果表明,模拟波面与被测波面吻合,证实了这种方法可行并且在一定条件下能进行高精度检测.%A large aperture and high precision optical system is required for optical wavefront detection.This article conducts simulation for the optical wavefront caliber of 513 mm.Aperture of 5 mm pentaprism is used for two-dimensional scanning detection of wavefront.The experimental results of the measured wavefront are fitted to the characteristic curve.The fitting characteristic curve is used to recover the three-dimensional wavefront.The errors in the experiment are analyzed.Simulation and experimental results fit very well,verifying the feasibility and that the method can perform highly precise detection.
