  • Fiber optic gyroscope bias modulation amplitude determination
    Patent number: 5196904
    Abstract: A bias modulation amplitude monitoring system for a rotation sensor having a pair of output signal component detectors to provide magnitudes of the corresponding frequency components in that signal which are used by a component relationship determination arrangement capable of adjusting the output signal to have a selected value in a range of values for a selected rate of rotation thereof, and to correct variations therein.
    Type: Grant

    Date of Patent: March 23, 1993
    Assignee: Honeywell Inc.
    Inventors: Preston Dane, Rudolf C. Dankwort, Tamim F. El-Wailly
  • Demodulation reference signal source
    Patent number: 5148236
    Abstract: An information retrieval system for extracting information from a pair of substantially coherent electromagnetic waves represented by phase differences therebetween each of which is incident on a photodetector, and having a demodulator which receives the photodetector output signal and which also receives a reference signal. The reference signal is obtained through use of a phase shift detector which receives the photodetector signal to determine certain phase shifts occurring therein and provides this information to a reference signal supply to adjust the phase of its output signal which then serves as the reference signal for the demodulator.
