Experimental Observation of Low Noise and Low Drift in a Laser-Driven Fiber Optic Gyroscope
Backscattering drift backscattering noise fi ber optic gyroscope laser phase noise
2015/8/7
We demonstrate that by driving a fiber optic gyroscope (FOG) with a laser of relatively broad linewidth( ), both the noise and the bias drift are reduced to very low levels (0.058 and 1.1 , resp...
Measurement of reduced backscattering noise in laser-driven fiber optic gyroscopes
reduced backscattering noise laser-driven optic gyroscopes
2015/8/10
We report what we believe to be the first demonstration of a laser-driven fiber optic gyroscope (FOG) built with an air-core fiber. Its phase noise is measured to be 130 rad/ Hz. W...
