Abstract

A novel method for the temperature-insensitive measurement of the bending of a cantilever plate is proposed. It is based on the radiofrequency (RF) power measurement of the beat signal that has been generated from a dual fiber Bragg grating (FBG)-based sensing head. Another noticeable feature is that a sine-modulated amplified spontaneous emission from a directly modulated reflective semiconductor optical amplifier (RSOA) is employed as a broadband light source.
