Paper Abstract

This paper presents a sensing head based on a Bragg grating written in an elliptical cladding Hi-Bi fibre partially exposed to chemical etching for reduction of the cladding diameter. With this sensing head geometry different strain and similar temperature sensitivities are achieved.
