ABSTRACT

Synthesis and characterization are carried on 70µl citrate capped gold nanoparticles dispersed in N-(p-n-nonyloxy benzoic acid Liquid Crystalline compounds (LC). Further homomorphic filtering (HF) technique is used to reduce the multiplicative noise in the image. This technique provides frequency domain procedure to improve the appearance of an image by gray level range compression and contrast enhancement. Polarizing microscope connected with hot stage and camera is used to capture the textures of the compounds. The compound with dispersion of 70 µl exhibits same NC phases as compared with the pure 9OBA with reduced clearing temperature as expected and nematic thermal ranges are increased while performing DSC and POM. Keywords: Synthesis, Homomorphic Filtering, Polarizing Microscope (POM), Differential Scanning Calorimeter (DSC), Nano dispersion, Illumination, Multiplicative Noise, Reflectance.
