Imaging Receiver for Target Referencing of Adaptive Optical Systems: Performance and Comparison with Predictions,

Abstract

The imaging method for target referencing of adaptive optics systems in the presence of extended targets in turbulence is compared with the conventional method which assumes an unresolved glint target. The tests were performed with a tilt-compensation system. There is a degradation due to the imaging process, but the technique still gives satisfactory results well into the scintillation saturation region. The gain measurements agree well with the predictions based on the propagation model developed at Defence Research Establishment Valcartier (DREV). (Author)
