【Abstract】 The reflector array is used as pseudo phase conjugator in the common path/common mode adaptive optics system. The ability and the fidelity of the reflector array to provide pseudo phase conjugate of the incoming wave was analyzed. The phases of pseudo phase conjugate waves are simulated and the fidelities of different reflector arrays and different aberrations are calculated, while the aberration of the incoming wave is given in Zernike model. It is shown that the fidelity is detemined not only by the cells’ number and arrangement of the retroreflector array, but also by the aberration itself. Different kinds of aberrations will have different fidelities. Factors such as diffraction, dihedral error, surface precision, which can influence the fidelity of the retroreflector array, are discussed too.更多还原
