Control in Adaptive Optical Systems
IFAC Proceedings Volumes, 1989Abstract The first part of the paper deals with the problem of restoration of a continuous statement of the tracking problem m the class of functions of arbitrary smoothness when adaptive optical system with a modal phase corrector is observed on a discrete set of points.

Adaptive Optical Filtering: System Issues
SPIE Proceedings, 1988This paper discusses system aspects of adaptive filtering applied to narrowband interference rejection for direct sequence spread spectrum systems. Removal of strong CW interference can greatly improve the operation of downstream subsystems configured for detection of wideband signals.

Interferometer-Based Adaptive Optical System
2006Interferometer-based adaptive optics has an advantage of direct measurement of the wavefront profile. Nevertheless the majority of adaptive optical systems, realized so far, use other types of wavefront sensors, such as Hartmann sensors. Interferometric sensors have two problems: (1) a source of a coherent reference wave should be present and (2) in ...

Adaptive optics control system development
SPIE Proceedings, 2003This paper describes the current control system of the multi-conjugate adaptive optics (MCAO) test bench system that is being developed at the University of Victoria, BC, Canada. The design and analysis of a control system for an AO system employing a Micro-Electro-Mechanical-System (MEMS) based deformable mirror is presented.

A simplified adaptive optics system
SPIE Proceedings, 2003Affordable adaptive optics on small telescopes allow to introduce the technology to a large community and provide opportunities to train new specialists in the field. We have developed a low order, low cost adaptive optics system for the 1.6m telescope of the Mont Megantic Observatory.

High-Bandwidth Adaptive-Optic System
2002Abstract : This award was to procure a high-bandwidth adaptive-optic system. A system capable of operating at 20 kHz was contracted to be constructed by Boeing SVS, Albuquerque NM using hardware primarily furnished by Xinetics. The components and operational concept for the adaptive-optic system is described in this report.

Compact Adaptive Optics Systems (CAOS)
2002Abstract : As feasibility study has been conducted to investigate whether compact adaptive optical (AO) systems based on the use of transparent wavefront modulators are viable. The results presented here consider the generic properties of suitable wavefront sensor technologies and establish sufficient conditions for their exploitation. Schemes by means
