An accelerometer based on the measurement of spectral bandwidth and power of the reflected optical signal from a strain-chirped fiber Bragg grating(FBG) is presented.The FBG is glued in a slanted direction onto the lateral surface of a simply-supported beam around the center.The bandwidth and optical power change with the applied vertical acceleration through beam bending caused by weights which are fixed in the middle of the beam.Experimental results show that bandwidth of the FBG responds to acceleration ...
