Paper Abstract

Our group in the Astronomy Department at the University of Illinois is assembling an adaptive optics system that will be installed at the Coude focus of the Mt. Wilson 2.5-meter telescope. The aim of the program is to provide the means to test experimentally, at an astronomically excellent site, many of the newer concepts in laser guided adaptive optics. To accelerate the experimental effort, the system will be built, in part, from existing hardware and from design information provided by U.S. military research groups. Also in the spirit of expediency, the first laser guide star system to be installed at Mt. Wilson will be a single Rayleigh beacon produced by an excimer laser which also exists and has been tested elsewhere. The program as described here is neither final nor fixed because the hardware, the technology, the system configuration, and the ideas that drive it will continue to evolve during the five year duration of the project.
