Photosensitive films composed of dye, initiator, acrylic monomers, and polymeric film-forming binder, and their
use in recording volume phase transmission and reflection holograms are described. Systematic variation of monomer-binder
combinations reveals that the maximum attainable index modulation (hologram efficiency) increases with increasing
difference between the refractive indices of monomer and binder. Addition of plasticizer is also useful for increasing index
modulation. Thermal and wet chemical processing methods for altering hologram properties are described.© (1990) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
