Paper Abstract

Two novel quasi-distributed optical fiber sensor systems are presented using 'Optical Coherence Domain Polarimetry'. This technology utilizes the two polarization axes of a single length of hi-bi fiber as two independent optical paths and detects the positions of the discrete sensing units along the fiber with 'white-length' interferometry. The two systems presented can be classified as intensity and interferometric type, respectively by the way the system measures the relevant measurand amplitudes. Experimental results with the two systems performed as a distributed pressure and temperature sensor, respectively are also given.
