摘要
光波测距仪检验工作中的周期误差是三项主要的系统误差之一,周期误差中初相角的精度不仅与测试方法和仪器精度有关,而且与周期误差自身的参数振幅有关,因而使仪器的初相角不宜测准。这是同一台仪器两次进行周期误差测定时,初相角相差较大的主要原因。
The periodic error in the proof- test of EDM is one of the main system errors. The initial phases of periodic error not only depend on the testing methods and precisions of the instruments, but also depend on the swing parameters of itself. So the measurements of the initial phases always aren＇t correct. This is the first cause that the initial phase difference is large when the periodic errors are determined twice with the same instrument.
