Numerical simulations for adaptive optics system

The simulation methods for the adaptive optics (AO) system are studied. Based on the global structure of the AO system, the key principles for each module are first discussed systematically, including the wave propagation principles, wave-front representation, coordinates transformation between the coordinates considered, wave-front reconstruction algorithm and DM principles. The purpose of these discussions is to establish the theoretical foundations for the numerical simulations of the AO system. Then the simulation steps are described in detail and a series of numerical simulation results are given which validate the effectiveness of our simulation work.
