  • Fiber optic transducer for simultaneous pressure and temperature measurement in fluid flow
    Patent number: 7729567
    Abstract: The present invention relates a fiber optic transducer (FOT) and methods for measuring the pressure and temperature of a flowing fluid using such FOT, wherein such FOT contains a fiber optic having fiber Bragg gratings. The fiber Bragg gratings are measured during a flowing fluid to determine the difference in the change in wavelength exhibited by a reflected optical signal from the gratings.
    Type: Grant
    Filed: May 14, 2007
    Date of Patent: June 1, 2010
    Assignee: The Hong Kong Polytechnic University
    Inventors: Hang-yin Ling, Yong-ping Zheng, Kin-tak Lau, Pou-man Lam
  • Fiber Bragg grating tuner
    Patent number: 7507891
    Abstract: The present invention relates an instrument tuner possessing a fiber optic with a prewritten fiber Bragg grating. The tuner is suitable for providing more accurate instrument tuning, capable of not being subject to a tuner's subjectivity or distortions or electromagnetic interference.
