´On-spot´ interferometric optical coherence domain polarimetry for quasi-distribute temperature sensors

A novel ´quasi-distributed´ optical fibre interferometric sensor system is described. The positions of the sensors along an optical high-birefringence fibre are located by employing ´white-light´ interferometry when each sensor is a local interferometer producing independent measurand-induced phase signals. The experimental results with the system configured as a distributed temperature sensor are also presented.
