摘要：
The noise of wavefront sensor is a major noise source in adaptive optics system. Based on the infrared adaptive optics system at 2.16m telescope, the photon counting noise of wavefront sensor which was the photon counting shear interferometer and the error propagation in the course of close loop were analyzed in terms of servo control system. The noise power spectra, the servo transfer function and the open-loop and closed-loop root mean square noise error were deduced theoretically.
