The basic principle and the characteristics of a new kind of linear phase retrieval (LPR) wave-front measuring method were analyzed. It is proved that the unknown phase can be retrieved uniquely from only one far-field image with calibration in advance. The principle construction of wave-front sensor developed from the LPR algorithm was described. The performance of the LPR method was tested by numerical simulation on measuring the arbitrary disturbed wave-front. The results showed that the LPR method was feasible on a certain system aberration condition, and it had good ability on high-spacial resolution. In the lab, an experiment setup based on the LPR method had been built. The experiment results testified the feasibility of this method and it could realize highly precision measure by using less amount of detect elements.
