Abstract

A novel type of adaptive optical system based on direct optimization of system performance metric is studied. The optimization method is based on stochastic parallel gradient descent (SPGD) algorithm. Theoretical analysis, computer simulations, and experimental results under point source and extended source conditions are presented.
