摘要
基于Sagnac效应的大型激光陀螺仪是测量地球参数的核心设备。与小型的惯性导航陀螺仪相比,大型激光陀螺将转速测量的灵敏度和稳定性提高了6个数量级,性能提升使大型激光陀螺仪在地球物理、大地测量和地震学领域的全新应用成为可能。本文介绍的大型激光陀螺仪是目前用于研究地球参数(Earth Orientation Parameter,EOP)测量的重要技术手段,可直接通过测量地球自转旋转角速度解算世界时(Universal time 1,UT1)。相比较于国外大型激光陀螺仪的大量成功应用,国内还需要不断提高大型激光陀螺的研制应用水平,以满足高精度测量地球旋转角速度解算UT1的需求。
The large laser gyroscope based on Sagnac effect is the core equipment for measuring earth parameters.Compared with the small inertial navigation gyro,the large laser gyro improves the sensitivity and stability of speed measurement by 6 orders of magnitude,and the performance improvement makes it possible for the new applications of the large laser gyro in the fields of geophysics,geodesy and seismology.The large laser gyroscope introduced in this paper is an important technical means to study the measurement of earth orientation parameters(EOP)at present.Compared with the large number of successful applications of large laser gyros abroad,the development and application level of large laser gyros in China still needs to be improved constantly to meet the demand of high precision measurement of earth rotation angular velocity and calculation of universal time(UT1).
