Abstract

We present performance results from an experimental adaptive system based on a recently proposed adaptive optics control technique -- the decoupled stochastic parallel gradient descent (D-SPGD) optimization technique. The system consists of an opto-electronic Zernike wave front sensor implemented with a 128x128 element LC phase modulator from Boulder Nonlinear Systems and a 127 element LC phase modulator from Meadowlark Optics used as a wave front corrector. Results demonstrate that adaptive wave front correction using the D-SPGD optimization technique can provide efficient compensation of phase distortions.
