Identification of thermo optical parameters of 8ocb pure and nano dispersed liquid crystalline compound using image processing based IME method

Abstract

In the present paper synthesis, characterization and image enhancement studies have been carried out on 8ocb LC with dispersed ZnO nanoparticles in conjunction with identification of thermo optical parameters at various concentrations. The microscopic textures are analyzed with MATLAB tool to obtain optical parameters. Image processing methods are used to identify the behavior of optical transmittance, absorption coefficient and phase retardation calculated using proposed Illumination Map Estimation (IME) technique and compared with the available literature. The proposed image processing-based method is a simple experimentation procedure to identify the thermo optical parameters of liquid crystal compounds for various electro optic applications.
