Statistical Parameters of Some Ferroelectric Liquid Crystals through Image Analysis Technique

The phase distinction temperature of ferroelectric liquid crystals having left-side terminal chain lengths n=8 and 9 and the same right-side chain length m=6 (VC-145 and VC-144) have been taken into consideration for the present study. The image investigation technique in concurrence through polarising optical microscopy is proposed for the evaluation of statistical parameters. The optical textures of the above series of compounds are recorded at different liquid crystalline phase temperatures. The properties such as “mean, standard deviation, entropy, energy, contrast and homogeneity” are estimated by analysing the optical textures of the samples using MATLAB software and results are discussed. The image investigation technique is a novel, simple technique for analysing the above-said parameters.
