Abstract
Abstract An apparatus for recording Lippman holographic mirrors comprises an exposing volume optically coupled on one side with an index-matching fluid to the holographic material to be recorded. The volume is exposed on an adjacent side to a light beam expanded in one direction into a plane of light whose projection on the volume is a line. The line of light and the holographic material are moved relative to each other on an interrupted or a continuous basis to expose the holographic material.
