Paper Abstract

In this thesis, two kinds of photopolymer films sensitized by azure I and azure II respectively are fabricated and their important holographic characteristics including the sensitive spectral range of films, transmittance, diffraction efficiency (DE), the thickness of photopolymer films and refractive index modulation are compared. It can be found that the photopolymer film sensitized by azure II(sample 2) has more obvious advantages than the photopolymer film sensitized by azure I (sample 1)on the holographic characteristics from the absorption intensity and the optimum concentration of dye and the inner uniformity of sample to the photochemical reaction velocity and the optimum medium thickness. On the contrary, sample 1 has higher maximum diffraction efficiency and refractive index modulation than sample 2.
