Abstract

A method for vertical adjustment of displacement control of measuring beam flare spot for absolute laser ballistic gravimeters is described. This method is based on video registration of displacement trajectory of the measuring beam reflected from the corner reflector during the free fall of a body. The values and directions of the measuring beam angle relative to the vertical were determined using frame-by-frame processing of the obtained videorecording. It is experimentally established that the error of vertical adjustment does not exceed \(3\times 10^{-5}\) rad

弹道重力仪中干涉仪光束的垂直调整

摘要

描述了一种垂直调整绝对激光弹道重力仪的测量光束耀斑的位移控制的方法。该方法基于在身体自由下落期间从角反射器反射的测量光束的位移轨迹的视频配准。使用获得的视频记录的逐帧处理来确定相对于垂直方向的测量光束角的值和方向。实验确定垂直调整的误差不超过\（3 \乘以10 ^ {-5} \） rad
