中文摘要	In wavefront sensor-less adaptive optics systems, wavefront sensing is often replaced with far-field detection. If the detection is inaccurate, even if the optimal performance metric is achieved, the correction quality may still be poor. In this paper we focus on the effects of improper far-field detection positions. At first we build a simple modal of a wavefront sensor-less adaptive with improper detection position. Then a series of analyses are carried out using this modal and the precision of placing far-field sensor is concluded. Finally simulations with practical systems are presented and the method for analysis are given. © 2014 SPIE.
