Abstract

When work started in 1965 using the Sagnac effect for rotation rate sensing the optical fiber had just been invented giving the ring laser a lead time of ~10 yr over the fiber gyro. In contrast to the ring laser, most of the European fiber gyro development effort seeks low accuracy (1°/h drift rate) and low- cost applications. But from theory there is the same accuracy potential for the fiber gyroscope as for the ring laser.
