Abstract
Abstract The nonlinear response and strong coupling of control channels of micromachined membrane deformable mirror (MMDM) devices make it difficult to obtain the desired optimal surface shape of the MMDM. In order to overcome these limitations, the wavefront modal reconstruction algorithm based on particle swarm optimization (PSO) is proposed, which is used to find the optimal control voltages of the MMDM. It is initialized with a population of random solutions and searches for optima by updating generations. In this way the objective function can be optimum and influence of phase aberration can be reduced to minimum. The simulation results show that this algorithm could find the optimal MMDM shape which was applied to correct phase aberration.
