Improvement of drift stability of a fiber gyro by ratio recording

The drift stability of a nonreciprocal simple fiber rotation sensor without phase modulation can be considerably improved by detecting the intensity ratio of two interference patterns. A linear zero point drift stability of 5°/h 2 and a noise equivalent rotation rate of 1.5 0/h were achieved.
