Abstract

The illumination of the edge of a hologram to generate a reference beam is the most important and difficult problem in making edge-illuminated holograms. We introduce a method for preshaping the reference beam which converts a spot into a broad uniformly illuminated strip, which can be either diverging or collimated, through the use of a combination of cylindrical lenses and slits. The preshaped beam illuminates the edge of the hologram's glass substrate at close to normal incidence. Based on the above, some ways to decrease the reflection loss and to increase the transmissivity in the emulsion are presented. Furthermore, we calculated several cases and gave an approach to find the best beam ratio of the reference to the object wave in edge- illuminated hologram making.
