摘要: 在开环光纤陀螺的基础上,采用锯齿波相位调制实现相移补偿,组成闭环光纤陀螺样机。通过对补偿相移特性的分析提出利用一种比较简单的实验方法,综合分析陀螺的线性度误差,对提高线性度有重要意义。本文给出了由锯齿波回扫时间引起的频差的实测结果。

Abstract: A closed-loop fiber-optics gyro is composed of an open-loop fiber-optics gyro with an electro-optical modulator to realize phase compensation. With analysis of the phase-shift compensation character, an experimental method for determining linearity error in gyro output is provided in this paper. The method exhibits the significance for enhancement of gyro output linearity.

Key words: fiber-optics gyro, phase-shift compensation, linearity error
