A New Method of Phase Diversity Wave-front Sensing Based on SOFM NN
基于自组织映射神经网络的位相差异波前传感新方法

A method based on the Combination of Phase Diversity(CPD) with neural networks(NN) was proposed,which is Phase Diversity Wave-front Sensing based on Seef-organizing Feature Map (SOFM) NN.The characteristic of SOFM NN and the basic principle of this method were introduced.The performance of this method was evaluated and analysed by computer simulation.The simulation results show that this method can improve the speed of PD Wave-front Sensing and reduce the size of training set effectively.It has a potential value of practical application.
