A New Kind of Heterodyne Fiber-Optic Gyroscope

Abstract

In this paper a novel fiber optic heterodyne detection technique of rotation rate is described. Using electro optic frequency and highly birefringent single mode fiber, the heterodyne fiber optic gyroscope system no more needs the use of acousto optic devices and is free from the direct current drift in the electronics. In addition, the reciprocity of the optical path in the system is improved. Preliminary experiments have shown a good linearity of the scale factor. Chinese Translations; Chinese. Reprints. (JHD)
