Abstract :
A new scheme for simultaneous strain and temperature measurement using a single fibre Bragg grating is proposed. The Bragg grating was written on the splice joint between two fibres and has two Bragg wavelengths, which show the same strain dependence but different temperature response and hence can be used for strain/temperature discrimination
