Reflective holograms on thermoplastic-photoconductor media

Abstract

It is possible to record holograms on a thermoplastic-photoconductor medium coated over a reflective substrate. Both analysis and experiment will be presented. The analysis shows that during recording only the interference term responsible for the formation of the primary image generates significant electrostatic fringes while other interference terms contribute insignificantly to electrostatic fringe formation. In the reflective readout mode, two reconstructed images are superimposed to give a three- to fourfold increase in the diffraction efficiency.
