A triaxial fiber Bragg gratings (FBG) accelerometer has been designed and tested yielding encouraging results. In the first prototype, only the vertical axis was instrumented. Tests have shown a good linearity in the amplitude response and that, in principle, temperature compensation can be achieved due to the use of FBG sensors with 180/spl deg/ out-of-phase response. The frequency range of the first prototype was limited to the cut-off frequency of the optoelectronic circuits employed in the experiments, however, tests up to 800 Hz were conducted and the FRF of the accelerometer may be considered satisfactory.
