| 摘 要： | 温度是影响光纤陀螺输出精度的主要误差源。为了有效提高光纤陀螺的输出精度，在光纤陀螺温度特性理论分析的基础上，对光纤陀螺进行了全温度范围（-30℃-＋70℃）速率试验和零偏试验，并对试验数据进行了深入分析，建立了光纤陀螺温度与标度因数、温度与零偏之间的多项式误差补偿模型。试验结果表明，该温度误差补偿模型可以使光纤陀螺在全温度范围的输出精度提高一个数量级，补偿效果良好。

| Abstract: | Temperature is the key factor causing output error of fiber-optic gyroscope （FOG）. To improve output precision of FOG, the temperature characteristic of FOG is theoretically analyzed, and zero drift test and rate test in full temperature range （ - 300℃-＋ 700℃ ） are conducted. Based on the analysis of the experimental data, error compensating models of temperature versus zero drift and temperature versus scale factor are established using polynomial method. Experimental results indicate that the compensation model can improve output precision of FOG in full temperature range by one order of magnitude. |
