Abstract
The coherent scattering noise properties were investigated adequately of a blue laser sensitized holographic photopolymer material. The noise gratings formed in this kind of photopolymer material with single-beam exposure was examined. The measurement of bidirectional scattering distribution function (BSDF) was used for reference to study the spatial distribution properties of scatter noise. The experimental results showed that the scattering noise buildup was faster in those photopolymers with higher initial transmittance which owe to more monomer or more photosensitizer dye, and faster buildup of scattering noise is corresponding to larger FWHM (full width at half-maximum of scanning readout) of scattering noise in spatial distribution.
