A vibration sensor is realized using PMMA (Polymethyl Methacrylate) fiber optic probe as sensor. The probe consists of two fibers, one is transmitting fiber and the other is receiving fiber. In this technique the sensor is non-contact and do not perturb the source of vibration. A portable high performance NI-DAQPad6016 with LabVIEW software is used to interrogate the vibration. The amplitude resolution of the sensor is 1µm within the frequency range 1-300 Hz. The thermal effect on the sensitivity of sensor is minimal. The sensor is suitable for real time monitoring of low frequency vibration and is of low cost and portable.
