Paper Abstract

Many holographers either mount their subject matter on its side or, if they use an overhead reference beam, mount the reference mirror on supports on the optical table. Both methods are artistically limiting and inherently unstable. The paper describes a method of supporting an overhead reference mirror and subject illumination in a manner that is inherently stable, using a gantry constructed from scaffolding pipe with KeeKlamp connectors. This gantry system not only provides versatility in possible lighting set-ups, but also forms a frame for a novel kind of draft exclusion material, and provides a substantial contribution to the rigidity of the table itself. Examples of table layouts of varying degrees of complexity, all designed for maximum stability, are shown. Finally, methods of keeping exposure time to a minimum by careful control of both optical geometry and processing conditions are discussed.
