Abstract

In a rotation-sensing fiber-optical Sagnac interferometer, temperature fluctuations and mechanical vibrations affect the birefringence of the fiber and may cause phase shifts like those resulting from rotation. Insertion of polarizing elements, acting at both ends of the fiber, yields a stable phase.
