| Abstract | A novel real-time aberration correction system using feedback interferometry and a multi-segment mirror for the wavefront corrector is described. The result is a simple and high-speed adaptive optics system demonstrating that feedback interferometry may potentially be an alternative method to conventional aberration correction techniques. Its high-speed processing and simplicity makes real-time correction practical. Our results show that the system can respond up to 37Hz for sinusoidal phase variations with amplitude of one wavelength and improves Strehl ratio significantly. © 2002 Elsevier Science Ltd.
