Abstract : A simplified signal processing technique for the open-loop fiber optic gyroscope is described which is based on the electronic closed-loop phase-shift nulling' concept. The system provides a linear output from an open-loop gyroscope configuration over a i2 pi radian range in Sagnac phase shift with good linearity and relatively low noise and drift. An alternative embodiment is disclosed utilizing, for example, a Mach-Zehnder interferometer for mixing the signals.
