Computer Simulation of Adaptive Optical Systems
Abstract
In this report the authors discuss adaptive phase compensation for the effects of turbulence and thermal blooming. Closed-loop systems employing both outgoing-wave and return-wave control algorithms are considered, although the authors have obtained quantitative estimates of system performance only for the return wave-type of system. On the basis of results obtained from a computer simulation of such systems, they conclude that adaptive optical systems employing a return-wave control policy will yield only limited compensation for the effects of cw thermal blooming unless the target has glints that are significantly smaller than the diffraction-limited width of the beam. Analytical and computer simulation results have also been obtained for the dependence of mirror fit on the number of mirror actuators.
