| 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. |

| Keywords: | fiber-optics gyro phase-shift compensation linearity error |
