Control Results and Improvements for the ALFA Adaptive Optics System

Professor Doug Looze
Department of Electrical and Computer Engineering
University of Massachesettes

Adaptive optics systems are employed to reduce the effect of atmospheric turbulence in optical systems. This talk will review the principles of adaptive optics and describe the design of the ALFA (Adaptive Optics with Lasers for Astronomy) system that is implemented on the Calar Alto 3.5m telescope. Recent results using the ALFA system will be presented. The talk will identify several current limitations of the ALFA system and discuss approaches that are being pursued to rectify these limitations.
