  • Abstract
    The nonlinear response and strong coupling effect of control channel in Deformable Mirrors make it difficult to obtain the desired mirror surface shapes. An efficient nonlinear model of deformation with respect to input voltages is presented using a back propagation neural network (BPNN). The residual relative error of the proposed model shows the improvement of accuracy of an order about 5 as compared to that of linear model, and with no significant increase of time.
