LSI has been involved in the development of optical gyros for 17 years. Early work 1 (1969 to 1975) included a passive gyro approach that measured a change in polarization state as a function of Sagnac phase. From 1979 to the present, LSI has been actively developing a passive optical rate sensor using fiber and integrated optics. The present sensor design is a closed loop interferometer approach designed to be insensitive to changes in source intensity and wavelength.
