This article reports the principle of operation, design aspects, experimentation, and performance of an extrinsic fiber optic probe for the calibration of accelerometers. The device consists of fiber optic transmitter, fiber optic probe, minishaker type 4810, power amplifier type 2706, accelerometer, conditioning amplifier, dynamic signal analyzer, photodiode detector, and a digital multimeter. In this technique, the vibration amplitudes are measured simultaneously using an accelerometer and extrinsic fiber optic probe and the results are compared. The agreement between the results obtained from accelerometer and from the fiber optic probe method shows that the latter can be a promising alternative technique for the measurement of vibration amplitude and hence for the calibration of accelerometers. The stability of the sensor, high sensitivity, and the simplicity of the design, low cost of fabrication, make it suitable for real field applications. © 2007 Wiley Periodicals, Inc.
