This paper reports the principle of operation, design aspects, experimentation and performance of a polymer fibre optic probe for the measurement of acceleration. The device consists of fibre optic transmitter, fibre optic probe, mini-shaker type 4810, power amplifier type 2706, accelerometer, conditioning amplifier, dynamic signal analyzer, photodiode detector and digital multimeter. In this experiment acceleration is measured simultaneously for different driving voltages of the power amplifier by fibre optic method and from the accelerometer with the help of dynamic signal analyzer and conditioning amplifier. The experiment is repeated with different frequencies of vibration (150, 250, and 350 Hz) and the results are compared. The value of acceleration obtained from accelerometer and the fibre optic probe method are found to be in good agreement with each other. The sensor is capable of sensing acceleration ranging from 40 to 1256 m/s² within a frequency range of 150 to 350 Hz. The fibre optic sensor is a promising alternative to other well-established methods for the measurement of acceleration due to its simplicity, long term stability, low power consumption, linearity, noise reduction, ruggedness and light weight of the reflective surface mounted on the accelerometer.
