Paper Abstract

Holograms made using beam paths separated by a beamsplitter require ultrastable environments if good results are to be obtained at exposure times longer than a fraction of a second. By placing components close together and eliminating the beamsplitter, the optical system can be made almost immune to most causes of instability. A family of such configurations, dubbed bypass holograms, is described, including one which fortuitously produces eight images in various orientations in a single exposure. Methods of maximizing emulsion speed and thus reducing exposure times are also discussed.
