| Реферат: | eng: A method of setting the vertical by monitoring the measuring beam flare displacement in absolute laser ballistic gravimeters is described. It is based on a video recording of displacement trajectory of a measuring beam reflected from a corner reflector mounted on a free-falling body. The magnitude and the angle of the measuring beam deflection from the vertical are determined by a frame-by-frame processing of the captured video sequence. An experimental verification of the method has shown that the error in setting the vertical is less than 3×10-5 rad, thus its contribution to the total determination uncertainty of g does not exceed 5×10-9 m/s2. |
