激光陀螺抖动偏频解调与微小角速度检测

Decoder of Dithered Laser Gyro and Micro Angular Rate Measurement

—本文讨论了激光陀螺抖动偏频解调与微小角速度检测的主要技术难点。针对难点，在整周期采样解调基础上提出了脉冲边沿触发鉴相解调方案，同时对该方案的合理性进行了详细分析和理论证明。文章最后指出，该方案对大角速度的高精度检测同样适用。

This paper relates to the major problems in the decoder of the periodic bias signal added to the dithered laser gyro when used to measure micro angular rate .A new method named as pulse edge strobing decoder is presented to solve the problems .The principle of this method which is based on dithering periodic sampling is analyzed and proved theoretically.At the end of this paper ,it is pointed out that the new method can also be used to the precise measurement of high angular rate.
