摘要：

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. © 1990, The Institution of Electrical Engineers. All rights reserved.
