Abstract

An experimental study on the Hartmann type wavefront tilt sensor is carried out at photon noise limitation. The experimental results and analyses show that A/10 sensitivity of wavefront tilt detection for space objects with about 8th astro- nomical magnitude within 1 ms of time has been achieved. An algorithm and computer program related to the luminous flux and corresponding photo-electron rate for wavefront sensor based on photon counting technique has been established and verified by experiments.
