电光调制器在光纤陀螺中的应用研究

Study on Applicat1on of Integrated-Optic Phase Mpdulator in FOG

本文分析了集成光学电光调制器的应用特性；并以方波相位偏置调制为例，研究了光纤陀螺中的相位调制误差；提出一种在光纤陀螺开环调试中测定光纤环传输时间和调制器半波电压的实用方法。

In the paper,the performances and characteristic parameters of IOPM(Integrated- Optic Phase Modulator)are discussed in view of the imporiant devices of FOG. The bias modulation effects and errors driven by square signal are studied experimently,then a kind of the online methods to measure the transmitting time of optic fiber coil and modulation coefficient kp are presented originally and tested successfully.
