  • Distributed fiber grating sensing systems using birefringence fiber interferometers for detecting wavelength shifts
    Patent number: 6298185
    Abstract: A distributed fiber-grating-based sensing system, the system comprises one or more scanned birefringence fiber interferometers to detect the small wavelength shift of the light reflected from the fiber grating, a wavelength demultiplexer to separate the lights from each fiber grating, a reference fiber grating for determining the absolute optical wavelengths. Compared with the prior art, the system has advantages of easier fabrication, better stabilization, and can be customized for different applications.
