  • FIBER OPTIC PARTICLE MOTION SENSOR SYSTEM
    Publication number: 20100313658
    Abstract: A sensor apparatus combines an optical sensor in which acceleration, acoustic velocity, or displacement (vibration) causes a corresponding shift in the center wavelength of the sensor output, coupled to a high speed interferometric interrogator, through an unbalanced fiber interferometer. The unbalanced interferometer functions to translate optical wavelength shift into phase shift, which is easily demodulated by the interrogator.

  • Fiber optic MEMS seismic sensor with mass supported by hinged beams
    Patent number: 7743661
    Abstract: The present invention relates to an optic seismic MEMS sensor. More specifically, a proof mass is supported by a frame having supporting beams. The proof mass is positioned within the frame and has a hinged attachment to the beams. The proof mass has a sensor gap having a first reflector and a second reflector positioned at opposing ends of the sensor gap. An optical fiber injects light into the sensor gap and light is reflected to determine seismic movement of the proof mass with respect to the frame. Stops are provided for limiting the movement of the proof mass to minimize strain on the attachment of the beams and the proof mass.

  • Dual slope fiber optic array interrogator
    Patent number: 6778720
    Abstract: An apparatus and method is presented presented to provide wide dynamic range measurements of the input phase to a time domain multiplex interferometer array using a dual slope modulation method for interrogation. Features of the present invention include a topology capable of using only single mode fiber components and self-correcting processing approaches that reduce measurement errors providing high accuracy measurements and significantly reducing the cost of interrogation.
