Abstract
The holographic characteristic parameters of the material such as the diffraction efficiency,the exposure sensitivity,the refractive index modulation and the dynamic range with different thickness were studied.As the thickness of the photopolymer increases,the diffraction efficiency increases at first and then decreases;the exposure sensitivity and the refractive index modulation decreases continuously;the dynamic range decreases at first and then increases.And the trends of these changes are simply analyzed in theory.From the contract of the holographic characteristic parameters in different thickness,it can be seen that this photopolymer has an optimal thickness.
