基于萨格纳克效应的大型激光陀螺仪被认为是精确监测地球自转的合适传感器,可用于潜在的地面科学研究和重大工程应用,如世界时UT1精密测量,地球固体潮观测、旋转地震波探测、广义相对论预言引力磁效应等领域.激光陀螺的灵敏度随环形腔尺寸增大而提高,其运行的长期稳定性受环境变化的影响.本文从激光陀螺仪工作原理出发,梳理了温度、倾斜、气压和风等环境变化对大型激光陀螺仪灵敏度和稳定度的影响,分析说明监测环境因素变化对其输出的萨格纳克频差修正和处置方法,为提高大型激光陀螺仪应用性能提供相关指导.
A review of environmental effects on large laser gyroscopes
Large laser gyroscopes,based on the Sagnac effect,are considered to be suitable sensors for precise monito-ring of the Earth's rotation for potential ground-based scientific research and major engineering applications,such as Universal Time 1(UT1),solid Earth tide observations,rotational seismic wave detection,and the testing of predicted gravitational magnetic effects in general relativity.The sensitivity of laser gyroscopes increases with the size of their ring cavity and the long-term stability of its operation is influenced by environmental changes.The paper explores the impact of various environmental factors on the sensitivity and stability of large laser gyroscopes.It delves into the effects of temperature,tilt,air pressure,and wind,and the Sagnac frequency difference correction and disposal method of monitoring the changes of environmental factors on its output are analyzed and illustrated,so as to provide relevant guidance for the enhancement of the application performance of large laser gyroscope.
