Dichromated Gelatin 필름의 홀로그램 회절효율

Time-dependent diffraction efficiency is measured during hologram formations in a dichromated gelatin film. It is observed that the refractive index modulation is strongly nonlinear with exposure time and intensity. In order to explain the complicated hologram formation dynamics, we present a phenomenological model for photoinduced refractive index changes by assuming that two photochemical reaction centers are responsible for the hologram formations. We also measured the polarization dependent diffraction efficiency for various incident angle.
