摘　　要：本文根据双光束激光测速仪的工作原理,针对常见的校准需求,基于实际情况,将数显卡尺、时间间隔发生器和时间间隔测量仪作为主要标准器,对测速间距、速度进行校准,并对校准结果进行不确定度评定,从而为相关单位的校准提供参考。In this paper,according to the working principle of the dual-beam laser velocimeter,aiming at the common calibration requirements and based on the actual situation,the digital caliper,time interval generator and time interval measuring instrument are used as the main standards to calibrate the velocity measurement interval and speed,and the uncertainty evaluation of the calibration results is carried out,so as to provide reference for the calibration of related units.
