A cantilever beam and fiber Bragg grating are used to measure acceleration. The output signal is insensitive to temperature variations from −20°C to 40°C, and the output signal fluctuates less than 5% without any temperature compensation schemes. For the experimental system, a linear output range of 8 g can be detected. © 2003 Wiley Periodicals, Inc.
