Abstract
Owing to small and coupled response of control channels of the continuous membrane deformable mirror(CMDM) and effect of system error on the its influence function,sometimes,the control voltage of wavefront modal reconstruction is beyond the the control voltage range.The modal reconstruction of wavefront based on the simulated annealing was put forward,which was used to find the optimal control voltages of the CMDM through verifying the total solutions in the feasible field.By the way the target function can be optimal and influence of incidence aberration can be reduced to minimum.Initial aberration of the adaptive optics can be replaced by the random wavefront aberration of human eye.Compared to the ways such as direct-solution or close-loop,the simulated annealing have prefer precision,credibility and least residual error.Because this algorithm has some better performance to reconstruct the incident wavefront,and refers to the nonlinear responses of the influence function,a new solution to correct the wavefront aberration by the CMDM is found.
