一、前言激光陀螺的问世,给转台的低速率测量创造了良好条件.它不但使测量精度有大幅度的提高,操作起来也十分简便.所以,激光陀螺也是速率转台精度测定的理想设备. 本文介绍用一台精度不太高(0.1度/小时)的激光陀螺测定WSY-81型转台速率的精度,获得了令人满意的结果.此转台将用来作为速率基准设备. I. Introduction The advent of laser gyroscopes has created a good condition for the low rate measurement of turntables, which not only greatly improves the measurement accuracy but also is very easy to operate, so laser gyroscopes are also the ideal equipment for measuring the accuracy of rate turntables. INTRODUCTION Satisfactory results have been obtained with the accuracy of the WSY-81 turret speed measurement using a laser gyro that is not very accurate (0.1 degrees / hour) and will be used as a rate reference.
