| 摘 要： | 谐振式微光学陀螺(RMOG)是一种基于光学Sagnac效应的新型角速度传感器.提出了基于模拟波形连续线性相位调制技术的偏置频率调制.与传统的双频率锯齿波调制以及数字调制方法相比,偏置频率调制消除了由于锯齿波回扫或数字波形中的台阶效应引入的脉冲噪声.从理论上推导了连续线性相位调制波形参数与陀螺的动态范围和灵敏度的关系,得...

| Abstract: | Resonator Micro-Optic Gyro(RMOG),based on Sagnac effect,is one of the new rotation-rate sensing devices.Bias-frequency-modulation(BFM) induced by analog continuous linear phase modulation technique is presented in RMOG.Compared with the traditional serrodyne phase modulation or digital phase modulation methods,the proposed modulation technique has the intrinsic advantage in free of sweeping-back or step-effect,eliminating the pulse noise induced by the discontinuous waveform.The influence on dynamic range a... |
