A phase-modulation approach to closed-loop fiber-optic gyroscopes is described that uses an all-fiber gyroscope, which can provide a linearized scale factor. Preliminary experimental results with manual closing of the feedback loop show good linearity in the scale factor. This approach has, in theory, an inherent suppression of source-wave- length dependence of the scale factor.
