Study on Hartmann Shack Wavefront Sensor Subaperture Mergence

Chen Li Yu Xin (Department of Opto Electron Engineering, Beijing Institute of Technology, Beijing 100081) (Received 1 April 1999; revised 30 July 1999)  
When the atmospheric turbulence is weak and the detected beacon is faint, adaptive optics system need to work at partial correction with subaperture mergence. Based on the Hartmann Shack wavefront sensor of the 1.2m high resolution adaptive optics system at Yunnan Observatory, two methods of subaperture mergence are studied in this paper on the Hartamann spot centroid error, and some valuable results have been obtained.
