A tracking and stabilization oriented fiber optic gyroscope

We demonstrate for an unpolarized Fiber Optic Gyroscope (FOG) with open-loop electronics, that, by applying more source power and conserving optical power in the optical path, we can achieve improved Angle Random Walk (ARW) performance without enlarging loop or put in multiple turns of fiber. The predicted trends are demonstrated by the experiment in terms of bandwidth. Power-law dependency is shown within the accuracy of the instrumentation.
