Microelectronic very large scale integrated systems for adpative optics and advanced imaging

摘要

We show that custom adaptive very large scale integrated (VLSI) circuit controllers can directly control commercially available wavefront phase correctors. These conrollers achieve real-time waveforont compensation under conditions of strong intensity scitillations. Their control strategy is based on the optimization of a measurable performance index. Optimization is carried out using parallel perturbative stochastic gradient descent. We describe VLSI image-plane processors designed to compute a variety of application specific performance metrics in real-time.
