Abstract

Keywords: nematic liquid crystal, grid pattern, image proces sing, dimensional analysis. Grid pattern (GP) is observed on planarly aligned nematic liquid crystal 4-methoxy-benziledene-4-n-buthyl-aniline (MBBA) when it is applied by a certain frequency and a certain voltage that exceeds a threshold voltage, VGP. The GP appears due to convective movements of MBBA molecules. Dimensions on GP are distinguished into the length and width of GP rectangular shape. Width-area of GP is a product of the length and the width. Dimensional analysis is carried on image processing using ImageJ software. Observation on the pattern shows that the frequency affects GP dimensions, which are proportional to the GP length and inversely proportional to the GP width. Variation on frequency also shows that the frequency is inversely proportional to GP width-area. Dimensional analysis also describes a quadratic relation between frequency and width-area of GP.
