摘要
激光散射和光电子技术是目前测试液晶特性最先进和可靠的手段 .此技术通过静态光散射和动态光散射两种测试方法 ,测得液晶的分子量、浊度系数、相关长度、相变温度、展矩和扭矩等许多物理参数 ,因此可判断液晶的类型 ,了解液晶的结构、形态 ,相转移及动态变形的过程 ,为液晶在许多领域的应用提供可靠的理论依据 .
Laser light scattering is the most advanced and reliable method for measuring both the static and dynamic properties of liquid crystals. Many parameters such as molecular weight, optical turbidity, correlation length, phase transition temperature, splay pitch and twist can be measured by this technique. These parameters are very significant in the theoretical analysis of liquid crystals and their applications in optoelectronics.
