中文摘要: A kind of Multiple-Detecting-Branch (MDB) Shack-Hartmann wavefront sensor (SHWFS) with extremely large number of subapertures, in which the pupil is split into spatially several branches by a beam splitter and each branch is detected by a SHWFS with less subapertures comparatively, is proposed to use for the wavefront sensing of the adaptive optics system for extremely large telescope. All the signals from the CCDs of SHWFS must be synchronized by the specially developed hardware system. There are the angular error of the beam splitter and the circum-optical-axis rotary of CCDs besides of the error of the conventional SHWFS. In this paper, the principle of the MDB SHWFS is introduced and its errors are analyzed. The simulation and experimental results show that this kind of MDB SHWFS can be used to measure effectively the wavefront aberration of the total pupil.
