Abstract

Time delays inherent in the control systems of current and proposed adaptive optics systems could be eliminated by predicting atmospherically-distorted wavefronts a short time ahead. An error-backpropagation neural network trained on real astronomical data has demonstrated that time series of wavefront tips and tilts (slopes) in the visible, and piston (displacement) in the infrared, are predictable to a degree which would improve the operation of an adaptive optics telescope.
