ABSTRACT
Depending on the type of adaptive optics system, first determine the appropriate performance evaluation function J, and the relationship between the performance evaluation function control vector u(r) between the unknown, ∇J[u(r)] by measuring only data to determine. SPGD algorithm derived from the theory of stochastic approximation parallel perturbation stochastic approximation (SPSA) algorithms and artificial neural network technology in the random error descent algorithm, using parallel perturbation gradient estimation techniques, and therefore belongs to no model optimization problems.
