Three fibers of 0.75, 1 and 1.5mm diameter are chosen with nine pair combinations for vibration measurement. From displacement response, it is observed that the sensitivity of the sensor increases as the diameter of the RF decreases and vice versa. The test results show that the frequency range increases when the RF diameter is less than the TF and vice versa. The resolution of the sensor also increases when the difference in diameters of the TF and RF decreases and vice versa. Moreover it is evident from the results that the dynamic range, range of frequency can be optimized by choosing the suitable diameter of the TF or RF as for the application.
