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
