| 摘 要： | 本文用实验方法研究了光致聚合物的曝光时间常量、曝光能量常量、动态范围、曝光灵敏度和折射率调制度等高密度全息存储参量随样品厚度的变化规律,结果表明随着样品厚度的增加,曝光能量常量、曝光时间常量及材料的动态范围也增加,但材料的曝光灵敏度却减小,而折射率调制度却没有明显的变化规律.

| Abstract: | The dependence of photopolymer high-density holographic recording parameters such as exposure energy constant,exposure time constant, dynamic range,refractive index modulation and sensitivity on the thickness were studied experimentally.It shows that with the increase of sample thickness,the sensitivity decreases,the exposure energy constant ,exposure time constant and dynamic range increase,but the change of index modulation is irregular. |
