本文介绍长距离精密准直方法和研制成功的激光精密准直装置。该装置对960m准直距离的测量不确定度为0.16mm;用于建立3km火箭滑轨基准线,其合成不确定度<0.39mm。
This article describes the long-distance precision collimation method and the development of a successful laser precision collimator. The device has a measurement uncertainty of 0.16mm for the collimation distance of 960m. It is used to establish a baseline of 3km rocket slide with a combined uncertainty <0.39mm.
