俄罗斯一家公司研制成一种便携式激光垂直仪。该仪器的激光传感器安装在立柱或活动模板上 ,传感器以垂直光线的形式发出射线 ,这条射线从激光器的两端射出 ,因此能从两个方向实现对立柱的严格标定。装有光靶的记录仪把激光垂直仪和刻在目镜上的测线结合到一起。需要时可拍下已?
A Russian company developed a portable laser vertical instrument. The instrument’s laser sensor is mounted on a post or moving plate. The sensor emits rays in the form of vertical rays that exit from the laser. This allows for rigorous calibration of the column in both directions. A logger equipped with a light target combines a laser plume and a line engraved on the eyepiece. Need to be photographed already?
