准直光管角度分划示值一般用来校准小角度光学仪器,在靶场试验中主要用于校准校靶镜、瞄准镜等火炮瞄准仪器,其示值需要定期进行校准和溯源。提出了采用经纬仪对准直光管角度分划示值误差进行校准溯源的方法,建立了测量模型,进行了测量实验和不确定度分析评定。结果表明,该方法满足量值溯源和传递要求。
Generally speaking, the angle-dividing indication of the collimated light pipe is used to calibrate small-angle optical instruments. In the shooting range test, it is mainly used for calibrating the target instruments such as calibration target and aiming goggles. The indication values need to be calibrated and traced regularly. The method of calibrating and tracing the indication error of the angle and the division of the collimated light pipe by the theodolite is proposed. The measurement model is established, and the measurement experiment and the analysis of the uncertainty are carried out. The results show that the method meets the requirements of traceability and delivery of quantity.
