Abstract

Future adaptive optics systems will require advanced predictive control algorithms that mitigate loop latency by forecasting disturbances. In many applications, such as laser communications terminals, synthesizing such controllers is challenging due to the non-stationary nature of the disturbance statistics over long periods. We present initial experimental results using a new, multichannel, adaptive control algorithm applied on the Integrated Optical System, an extreme AO system under development for the Laser Communications Relay Demonstration. The adaptive controller implicitly tracks disturbance statistics, and provides broadband wavefront control without the need for open loop downtime. The results illustrate the improved disturbance rejection capabilities of the controller compared to a traditional integrator, even when the exogenous disturbance statistics evolve.
