Abstract

The objective of this paper is to present in simple and condensed form,key physical aspects of adaptive optical systems so as to allow non-specialists to make first order estimates of performance and thus gain an appreciation of what such systems may offer in an application of interest. The historical review given at the outset of the preceding session indicated that two key components were required to implement such systems, namely a deformable or "rubber" mirror (or locally controlled refractor) and a wavefront sensor. In both elements spacial and temporal response capabilities adequate to the problem at hand were required. Once such wavefront correction and sensor devices were available, control theory suggested a number of the systems now covered under the generic name adaptive or active optics.
