  • Method of and apparatus for wavelength detection
    Patent number: 6822218
    Abstract: A reflected light from a Bragg grating in an electrical transformer or other apparatus at which temperature is to be measured, is positioned by an optocoupler through a second fiber provided with a second Bragg grating whose reflection wavelength is different from that of the first grating. The nonreflected light intensity is measured by a photodetector and is used to signal the temperature measurement.

  • Method for fiber optic temperature measurement and fiber optic temperature sensor
    Patent number: 6350056
    Abstract: Fiber optic temperature measurement, especially for electric power equipment is effected utilizing, as the sensor, a portion of an optical fiber from which the coating has been removed and to which a glass capillary has been bonded by an adhesive. The measurement is carried out polarimetrically and utilizes the change in birefrigence resulting from a temperature change because of the mechanical stressing of the sensor region of the optical fiber.
