Adaptation of adaptive optics systems

SPIE Proceedings, 1997
The designs of existing Adaptive Optical System are "unadaptive" themselves, it means the parameters of the systems, such as subaperture diameter d, dynamic range of wavefront distortion correction, frequency bandwidth, etc., are fixed. Since these parameters were mainly decided according to some statistic values of atmospheric disturbance and detected

Adaptive optics system simulator

Optics & Laser Technology, 2018
Abstract In this paper we present the development of a computational tool that simulates the behavior of the basic devices in an adaptive optics system. These elements are a deformable mirror, a Shack-Hartmann wavefront sensor and a basic control system.

SAAO adaptive optics system

SPIE Proceedings, 2000
After successful testing at the Raytheon facility in Danbury, Connecticut, the completed SAAO adaptive optical system has been shipped to the AEOS site on Haleakala, Maui, Hawaii. The system is undergoing final integration with the AEOS observatory. This paper describes the adaptive optics system design, including an overview of al major subsystems ...

Adaptive optical processing system with optical associative memory

Applied Optics, 1993
An architecture for a novel adaptive optical processing system using optical associative memory with learning capability is proposed. The optical system consists of an optical preprocessor for feature extraction and optical associative memory. The feature-extraction ability can give excellent processing capability to the optical associative memory.

Adaptive Optics Systems

2012
This chapter presents an overview of adaptive optics (AO) systems, including a brief summary of their development history and their importance in high-resolution imaging systems. The first section of this chapter introduces the basic optical concepts of wavefronts and aberrations.

Dynamic characteristics of optical adaptive systems

Applied Optics, 1987
The effect of time delay on characteristics of an optical adaptive system is considered. Classification of the optical adaptive systems as dynamic feedback systems has been made. Systems with constant delay, a highspeed adaptive system as well as a new class of systems, i.e., predicting adaptive systems, are investigated.
