Dynamic Wave-front Distortion Compensation with 134-control-channel Sub-millisecond Adaptive System
A 134-control-channel adaptive-optics system consisting of a microelectromechanical mirror array (μ-mirror), a wave-front tilt-control mirror, and a very large scale integration controller utilizing a stochastic gradient-descent optimization of a performance metric is presented. A maximum adaptation rate of ∼11,000 iterations/s was achieved. The system was used to demonstrate real-time compensation for dynamic phase distortions from a laboratory-generated turbulence simulator in a laser-focusing experiment.
