Gas mirror

Abstract

A gas mirror is an optical gas device deflecting a light beam and consisting of a flat plate on which a stable controllable distribution of the refractive index is created by a certain means. Working capacities of such devices are estimated and their experimental studies are carried out. Limiting geometric and optical characteristics of the gas mirrors are determined.
