Numerical simulation on a kind of linear phase retrieval wavefront measuring method
The characteristics of a new kind of linear phase retrieval(LPR) wavefront measuring method were analyzed.The process of calibration was discussed and the basic construct of the LPR was described.The influences of the system aberration,the characteristic of reconstruction matrix, and the coefficient of mode calibration on the performance of the LPR method were tested by numerical simulation.According to the calculation of the condition number of reconstruction matrix,the relationship between the target size and performance of LPR was discussed.The simulative results show that this method is feasible.
