Abstract

The polarization properties of the reflection-type holographic recording material, DuPont photopolymer OmniDex^TM 706, have been studied. Depending on the position of photopolymer-Mylar assembly, linearly polarized laser beam alters its polarization state about 40%. Due to the birefringence of Mylar substrate, this phenomenon has been occurred very randomly through a wide range and affected in diffraction efficiencies. In the case of reflection-type hologram, the directions of two beams incident onto the recording materials are not same, the change of the polarization states cause the weak fringe visibility. As a result, reflection holograms have shown low diffraction efficiencies and unstable characteristics.
