实验研究了聚合物分散液晶（PDLC）薄膜的角透射率随液滴尺寸、折射率和样品厚度的变化规律。为了考虑到PDLC的一些特殊特性所产生的额外散射现象，我们对实验数据进行了稍微修改的反常衍射近似解释。液滴的尺寸和聚合物与液晶之间的折射率差是影响光传输的最重要因素，此外还有额外的散射因素。
The angular transmission of Polymer Dispersed Liquid Crystals (PDLC) films has been experimentally investigated as a function of droplets dimension, refractive indices and thickness of sample. The experimental data have been interpreted in terms of the Anomalous Diffraction Approximation slightly modified in order to take into account extra-scattering phenomena generated by some of the peculiar PDLC characters. The dimension of the droplets and refractive index difference between polymer and liquid crystal are found to be the most important factors affecting the light transmission as well as extra scattering factors.
