Experimental studies of the development of nanoparticle based optical fiber humidity sensor with linear response over a large dynamic range

Abstract

The present thesis work is focused on the development of optical fiber relative humidity sensor with linear response over a widest possible dynamic range with an optimum sensitivity through a simple optical fiber sensor configuration A comprehensive experimental study is carried out employing three schemes namely evanescent wave EW absorption employing Zinc oxide ZnO as well as Titanium dioxide TiO2 nanoparticle immobilized nanostructured sensing fiber cladding direct guided mode exhau
