Paper Abstract

A simple and effective method of encapsulation of a fiber Bragg grating (FBG) sensor for use at elevated temperatures and harsh and corrosive environments using a rigid probe technique is presented in this paper. A thorough characterization has been carried out on the encapsulated, as well as bare, FBGs. The experimental studies reveal that encapsulated FBGs are superior in their responsivity, linearity, sensitivity, and repeatability when compared with unencapsulated ones.
