摘要
新型μ-base精密测距仪是一款高精度基线测距仪，它采用ADM测距原理，在使用角隅棱镜（CCR1．5“，RRR1．5”）时，其在160m的范围内的测距精度优于10μm。本文在分析ADM测距原理的基础上，利用双频激光干涉仪校准装置，采用“平面镜反射扩大量程”的方法，对仪器的测距精度、测程等指标进行测试，对测量的结果进行了评定和分析，并给出一些可较大程度保证其精度的使用条件和使用方法。
Applying the absolute distance meter （ADM） technology, the new μ - base is a kind of high - accuracy elec- tronic distance measurement （EDM）. The measuring accuracy is better than 10μm within the range of 160 meters using the cor- ner cube （ ＂CCR1.5, RRR1.5＂ ）. Based on the analysis of ADM principle, the measuring accuracy and range are tested with a dual - frequency laser interferometer using the method of ＂expanding range with plane mirror＂. The measuring results are evalua- ted and analyzed, and service conditions and application methods that can ensure the measuring accuracy are presented.
