Fiber-Optic "White-Light" Birefringent Temperature Sensor

Abstract
Passive multiplexing of a fiber optic temperature sensor network using spectral modulation encoding techniques in birefringent bulk materials is demonstrated. Various detection schemes are described and the consequences of the spectral dependence of optical properties for both transducer and demultiplexer are theoretically analyzed. The network organization choice is discussed and the first experimental evaluations of a breadboard network are reported (sensitivity, crosstalk, line losses effect).© (1987) COPYRIGHT SPIE--The International Society for Optical Engineering.
