【Abstract】 By using the concept of power spectra reject function which defined in this paper, the control effect of an adaptive optical system using direct gradient wavefront reconstruction algorithm was analyzed.Both the theoretical analysis and experiments on the 61 element adaptive optical system show that the direct gradient wavefront reconstruction algorithm will lead to the dropping of the control effect of the adaptive optical system.更多还原
