Paper Abstract

The limitations of a Hartmann type wavefront sensor are theoretically and experimentally studied based on photon counting technique. An experimental set-up for simulation of single subaperture adaptive astronomical telescope is described. The results of experiments and analyses show that a star of the 8th magnitude can be dealt with by this kind of wavefront sensors within 1 ms of time and with A/1O of wavefront distortion detection sensitivity. As for calibration of experiments, an algorithm related to luminous flux at entrance pupil of telescope and its corresponding photo-electron rate detected by the wavefront sensor is presented and yenfied by experiments.
