研究了全息形成的聚合物分散液晶光栅的反射/衍射效率提高背后的基本物理现象。使用光栅形成过程中的原位衍射测量确定的参数，一个现象学的扩散模型表明，在聚合物网络中的组合物调制的结果在共混低聚物系统。扫描电子显微镜的研究表明，聚合物的形态与这一假设相一致。(C)2000年美国物理学会。【S0003-6951（00）05216-5】。
The underlying physical phenomena behind the increased reflection/diffraction efficiency of holographically formed polymer-dispersed liquid crystal gratings formed from blended oligomers are investigated. Using parameters determined by in situ diffraction measurements during grating formation, a phenomenological diffusion model shows that a composition modulation in the polymer network results in blended oligomer systems. Scanning electron microscope studies reveal polymer morphologies consistent with this hypothesis. (C) 2000 American Institute of Physics. [S0003-6951(00)05216-5].
