A novel photodielectric polymer system suitable for recording high resolution volume phase holograms is described. Highly reactive monomers that polymerize rapidly when inserted between two substrates allow for simple and convenient preparation of recording layers ranging from 10microm to 3 mm. The materials have superior chemical and dimensional stability and have in situ self-developing capabilities. During recording the polymer cross-links in the irradiated regions causing changes in index of refraction. Experimental measurements reveal that the diffraction efficiencies may exceed 90%, that the resolution is in excess of 2000 lines/mm, that the angular selectivity may be as high as several minutes of arc, and that the noise characteristics are comparable to those of high quality photographic emulsions. The hologram formation mechanism along with experimental results of exposure sensitivities, diffraction efficiencies, SNRs, and angular discrimination are presented.
描述了一种适用于记录高分辨率体相位全息图的新型光介电聚合物系统。当插入两个基板之间时会快速聚合的高反应性单体，使得能够简单方便地制备厚度从10微米到3毫米不等的记录层。这些材料具有优异的化学和尺寸稳定性，并具有原位自显影能力。在记录过程中，聚合物在受辐照区域交联，导致折射率发生变化。实验测量表明，衍射效率可能超过90%，分辨率超过2000线/毫米，角选择性可能高达几分弧度，并且噪声特性与高质量照相乳剂相当。给出了全息图形成机理以及曝光灵敏度、衍射效率、信噪比和角分辨率的实验结果。
