摘要
数字水准仪的出现解决了大地测量仪器中水准仪自动读数与记录问题,对当代测量技术产生了积极的影响。文中介绍了如何采用双频激光干涉仪配合45°平面镜检测数字水准仪的方法,对精密光学水准仪和数字水准仪进行综合精度的评定和比较,并对结果进行了分析。
The appearance of digital level solves the problem of level＇ s reading in measuring instrument and makes more active effects in measuring technology at present. This article first introduces how to use laser interferometer and mirror placed in 45° to compare digital level with optical level, and then analyzes the accurate of the two kinds of levels. Finally it points out the advantage and shortcoming of them.
