关于陀螺经纬仪激光对点器同心度的检验

A calibration method for concentric degree of gyrotheodolite laser center-point equipment

仪器的对中精度直接影响方位测量(特别是短边方位测量)精度,而对点器同心度对仪器的对中精度有着不可忽视的影响。但对于对点器同心度的检验方法并未见之,本文由经纬仪互瞄的原理和性质,提出一种检验陀螺经纬仪激光对点器同心度的方法。该方法简单有效,对提高陀螺经纬仪的定向精度有一定的实用价值,并可在一定程度上实现精密对中。

The centering accuracy of theodolite affects the precision of azimuth survey （ especially over short line） directly, and the influence of the concentric degree of the optical plummet can not be neglected to the centering accuracy. But the calibration method about the concentric degree of the optical plummet had not ever been found. A method, which is about checking the concentric degree of the gyrotheodolite laser center-point equipment, was presented in this article according to the theory and character of theodolite mutu- al collimation. This method was simple and available, and it had practical value at a certain extent in improving the orientation accuracy of gyrotheodolite. The calibration method could also realize precise centering at a certain extent.
