Harsh environment fibre Bragg grating sensing

Abstract

Harsh environments conditions, long-term distributed sensing and long-term sensing implementations are a few typical examples where the characteristics of a sensing system which is optical has advantageous and can make an effective and more relevant solution as compared to a conventional electrical sensors system. In this chapter, we will briefly focus on the temperature measurement applications of fibre Bragg grating (FBG) sensors, together with their behaviour under high mechanical compression and gamma irradiation.
