摘要
2π复位调制是光纤陀螺全数字闭环处理技术的一个重要环节。由于小型化Y波导的半波电压提高,小型化光纤陀螺的调制信号达不到2π复位的要求。通过分析闭环复位的原理,提出了一种新的对称复位调制技术,成功实现了小型化光纤陀螺的复位调制闭环控制。
In Fiber Optic Gyroscope （FOG） system, one of the most important parts in full closed-loop control is 2π reposition modulation. Due to the increase of half voltage of miniaturized multi-functional integrated optic chip, the modulation signal in miniaturized fiber optic gyroscope can’t afford to the full range voltage of 2π. Based on the analysis of closed-loop principle, a new method was presented, which was called symmetrical reposition modulation, and the method can be well used to achieve the reposition modulation in closed-loop control to miniaturized fiber optic gyroscope.
