相位式测距仪周期误差新探

A Study of the periodic Error in the phase Geodimeter

本文论述了相位式测距仪中理论上未曾弄清,因而在实践中或者被忽视,或者被认为无法解决的谐波窜扰引起的周期误差问题和光窜扰引起的周期误差随距离增大的问题,提出了解决办法,并给出了实验结果。

This paper deals with two problems in the Phase Geodimeter. One of them is theperiodic error caused by harmonic interference. The other is the increase of the periodicerror proportional to distance, which is caused by photic interference. These are theproblems to which theory has no explanation, and therefore were unable to be solved inpractical work in the past. This paper analyzes the problems and offers methods to eliminate them.
