Paper Abstract

In the first period of the fiber-gyro development fundamental problems such as signal noise and bias stability (drift) had to be solved. By the use of light with short coherence length disturbing interferences were avoided and a noise equivalent rotation rate of about 0,1°/h (Bandwith 1 Hz) corresponding to a random walk of 1.2 10-3°/h was achieved. The reciprocal arrangement of the Sagnac-interferometer the so called 'minimum configuration' (Fig. 1) yield a bias stability of better than 0.1°/h. These data are sufficient for many applications of the fiber-gyro. Another important parameter is the scale factor error. There are only few reports on scale factor measurements. Up to now an accuracy in the range of 10-2-10-3 was achieved.
