一种新型陀螺仪信号提取方案的研究

Research of signal-obtaining system for a new type of gyroscope

介绍了用在新型陀螺仪上的一种赤道三角图形光电信号读取方案,建立了在转子转轴相对壳体坐标系有了偏移和偏转时的信号提取数学模型,分析了此时的偏转误差、耦合误差,最后给出了三种球面三角图形刻制方法,建立了各种方案的误差数学模型,分别给出了各误差仿真曲面,并在转子表面用此方法进行了初步实验,结果表明,图形边缘比较光滑,基本上可以满足本传感器的分辨率.

An optical signal obtaining scheme via triangle pattern engraved on rotor would be discussed. It＇ ll analyze the angular errors caused by coupling, engraving when there exists excursion and deflection to inertial space, study the method of engraving and do some relevant experiments. The results are helpful to the signal obtaining system of gyroscope.
