Paper Abstract

Low frequency vibration measurements in a composite material using embedded polarimetric sensor are presented in this paper. A glass fiber reinforced composite material sample is fabricated with two different polarimetric sensor types embedded in it. The two types of polarimetric sensors embedded are based on polarization maintaining photonic crystal fiber (PM-PCF) and Panda fiber. The vibration frequencies and amplitudes are measured using the embedded polarimetric sensors and the results from both sensor types are compared. Analysis of the limitations of Panda fiber based vibration measurements over PM-PCF is carried out and the results are presented. It is found that for high amplitude vibration measurements, PMPCF based sensors offer a wider linear range and are more suitable than Panda fiber based polarimetric fiber sensors. It is envisaged that the results from the studies will provide important information to end-users for selecting an appropriate sensor for vibration measurements in composite materials.
