Abstract
Linear dichroism is a novel method for texture analysis and is used to measure the order parameter of liquid crystals. It determines the dichroic ratio by analyzing the maximum absorption of textural intensities polarized parallel and perpendicular to the optical axis. To capture liquid crystal textures as a function of temperature, a polarized optical microscope with an attached camera is employed under parallel and crossed polarizer conditions. This analysis adheres to the Beer-Lambert law, relating transmitted and absorbed textural intensities in liquid crystals. Here, we investigate nematic liquid crystals, specifically 4-cyano-4′-pentylbiphenyl and p-n-alkyl benzoic acid (where n = 8), using texture analysis to study their physical characteristics.
线性分色法是一种新颖的纹理分析方法，用于测量液晶的阶次参数。它通过分析平行和垂直于光轴的偏振纹理强度的最大吸收来确定二色性比。为了捕捉液晶纹理与温度的函数关系，在平行偏振片和交叉偏振片条件下，使用了一台附带摄像头的偏振光学显微镜。这种分析遵循比尔-朗伯定律，即液晶中透射和吸收纹理强度之间的关系。在此，我们研究了向列液晶，特别是 4-氰基-4′-戊基联苯和对-正烷基苯甲酸（其中 n = 8），利用纹理分析来研究它们的物理特性。
