Retroreflector array is used as pseudo phase conjugator in the system. The fidelity of the conjugate wave and matching problem of the retroreflector array and Hartmann-Shack wavefront sensor is discussed. Several data fusion methods are presented in order to having two Hartmann-Shack wavefront sensors control one set of wavefront corrector. The misalignment errors of Hartmann-Shack wavefront sensor and arrangement errors of wavefront sensor and deformable mirror are analyzed. At the same time, numerical work based on the data of practically system, such as 61 element AO system, are done corresponding to the problem respectively and the results are given. The system of CP/CM AO is setup to fulfill all the functions. Through the data fusion of two Hartmann-Shack wavefront sensors, the system runs successfully and realizes the close loop. It lays a good foundation for the application of CP/CM AO. Another aspect of this paper is to expand the working band of Hartmann-Shack wavefront sensor through Frequency Transfer of Nonlinear Optics.
