【Abstract】 In this paper,Fourier transform evaluation of fringe phase is proposed for measuringaspherical mirror.The testing principle of phase deviation is described.The wave aberration estimationof aspheric surfaces by least-square principle instead of computer-generated holograms(CGH)compensation is also presented,and some errors of algorithm are discussed.更多还原
