Abstract
Brillouin scattering based distributed fiber optic sensors for temperature and strain measurement have been widely studied as a tool for structural health monitoring, since they use the entire fiber as the sensing part, unlike the conventional sensors. Among many Brillouin scattering based sensors, BOCDA can provide advantages of a higher spatial resolution (~mm order) and a higher sampling rate (~kHz) with random access of the sensing position. However, this comes at the cost of a limited measurement range (~several hundreds of meters) and complexity in the system configuration. In this paper, we report several studies for enhancing both the measurement range and the spatial resoultion in the BOCDA system.
