  • Patent number: 6377351
    Abstract: A fiber-optic laser gyroscope having phase sensitive detecting means which can reduce rotation rate measurement errors. In the fiber-optic laser gyroscope, errors due to the relative intensity difference between two consecutive pulses, which was an error factor in rotation rate measurement through time interval measurement between two adjacent pulses, can be eliminated by having a phase sensitive detection means which may extract and detect only components having the same phase as that of a phase-modulated signal from components having the same frequency as that of a phase-modulated signal. An output from the phase sensitive detecting means has an additional characteristic of being linearly proportional to rotation rate. The fiber-optic laser gyroscope of the present invention, therefore, has a characteristic of a relatively simple signal processing compared to conventional interferometric fiber gyroscopes.
