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 which is subsequently detected. The output signal is insensitive to temperature variations and for a temperature change from -20 degrees Celsius to 40 degrees Celsius, the output signal fluctuated less than 5% without any temperature compensation schemes. Because the sensor does not utilize expensive and complex demodulation techniques it is potentially inexpensive. For the experimental system a linear output range of 8 g could be detected.
