Abstract

A cantilever beam and fiber Bragg grating is used to measure acceleration. The cantilever induces strain on the grating, resulting in a Bragg wavelength modification that is subsequently detected. The output signal is insensitive to temperature variations and for a temperature change from -20°C to 40°C, the output signal fluctuated less than 5% without any temperature compensation schemes. Because the accelerometer does not utilize expensive and complex demodulation techniques, it is potentially cost effective. For the experimental system, a linear output range of 8 g could be detected.
