小型低成本激光陀螺标度因数与温度关系研究

为了更深入地研究小型低成本激光陀螺标度因数与温度的关系,在不增加硬件成本的前提下提高小型低成本激光陀螺性能,采用理论分析与实验相结合的方法,取得了定温度点和慢变温两种情况下标度因数随温度变化的数据。结果表明,标度因数随温度变化的实验数据与近似理论计算大致相符,用所得数据建立多项式进行补偿,能有效地减小标度因数的温度误差。

Relation between the scale factor and temperature of small low cost ring laser gyroscopes

In order to study the relation between the scale factor and temperature of small low cost ring laser gyroscopes (RLG) deeply, and improve its performance without increasing cost on hardware, theoretical analysis and experiments were carried out. Data of scale factor both in given temperature and in slowly changing temperature were obtained. Those experimental data conformed to the theoretical data approximately. The equation between scale factor and temperature was built and thus the scale factor error caused by temperature was apparently reduced.
