Study of Statistical Parameters through Image Analysis Technique of 16ABBA Liquid Crystal
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 8
Abstract
Study of statistical parameters of azomethine ester, 4-hexadecyloxy benzylidene-4’-bromoaniline (16ABBA) liquid crystal with image analysis technique is reported in this paper. Textures of the sample are recorded with polarizing optical microscope attached with hot stage and colour camera as a function of temperature. The sample shows enantiotropic smectic A and monotropic smectic B phase. Statistical parameters such as Mean, Standard Deviation, Entropy, Energy, Contrast, and Homogeneity, are calculated using image analysis technique using Matlab software. The results obtained shows abrupt change at the phase transitions. So, temperature dependence of statistical parameters will be applied to identify mesophase transition temperatures.
