Design of pressure sensor based on optical fiber Bragg grating lateral deformation

Abstract

This paper describes steps involved in the design and realization of a new type of pressure sensor based on the optical fiber Bragg grating. A traditional pressure sensor has very limited usage in heavy industrial environments, explosive or electromagnetically noised environments in particular. Utilization of optics in these environments eliminates all surrounding influences. An initial motivation for our development was research, experimental validation, and realization of a complex smart pressure sensor based on the optical principle. The main benefit of this solution consists of increasing sensitivity, resistance to electromagnetic interference, dimensions, and potential accuracy.This paper describes steps involved in the design and realization of a new type of pressure sensor based on the optical fiber Bragg grating.
