| 摘 要： | 对塞曼激光陀螺的补偿模型修正项、偏频原理进行了研究,由激光陀螺的输出特性,推导出补偿模型修正项最佳数量.在激光陀螺的工作温度范围内,其偏频量与温度具有良好的线性关系,可采用偏频量作为激光陀螺输出零偏的补偿基准,建立了一种基于偏频量的补偿模型,补偿后的激光陀螺精度得到显著的提高,新型补偿模型可以准确表征由于温度变化引起的激光陀螺输出误差,无需温度传感器及其配套电路,具有很好的工程应用前景.

| Abstract: | The compensation model and biasing theory were investigated to improve the precision of Zeeman laser gyroscope.Based on the output characteristic of laser gyro,the optimal number of the compensation model was deduced.It was found that the Zeeman biasing value can be considered to depend linearly on the internal temperature among the operational temperature.That is why it is potential to utilize the biasing value for correction model to compensating the zero drift of laser gyro changing with temperature.The ... |
