The Synchrotron Radiation Monitor (SRM) system has been designed and constructed at the Shanghai synchrotron radiation Facility (SSRF) for several years and runs good. However, the monitor extraction mirror deformation is quite common at different facilities, and other reflecting mirrors in the optic path also have surface error and angle error. As we decide to upgrade the SR monitor system at SSRF, this issue is also one of the most import thing what we should overcome. In order to verify the feasibility and evaluate the accuracy, simulations based on SRW code have been done. In this simulation, a dedicated algorithm was developed to reconstruct wavefront. The result and the algorithm is very useful for our experiment and upgrade program. In this paper, the algorithm and the experiments based on Shark-Hartmann wavefront sensor will be presented detailed.
