  • Distributed optical fiber temperature sensor based on optical fiber delay
    Patent number: 8734011
    Abstract: The present invention discloses distributed optical fiber temperature sensor based on optical fiber delay technology, including a tunable optical transmitter module, an optical receiver module, a signal processing and controlling module and multiple distributed sensing modules connected in series via transmission fibers. The multiple wavelengths optical signals transmitted from the tunable optical transmitter module respectively are transmitted into the first sensing module, and then transmitted out from the last sensing module. The output multiple wavelengths optical signals arrive at the optical receiver module. The optical receiver module converts optical signals of all wavelengths into electrical signals and transmits them into the signal processing and controlling module.
