METHOD OF INSERTING LASER BEAM VERTICAL LINE IN BALLISTIC GRAVIMETER AND APPARATUS FOR REALISING SAID METHOD

摘要

FIELD: physics.;SUBSTANCE: method involves monitoring displacement of a laser beam reflected from a freely falling body using a video camera, calculating the angle of deviation of the laser beam from the vertical using the recorded video and correcting the direction of the beam in the required direction.;EFFECT: high accuracy of inserting a laser beam vertical line in a ballistic gravimeter, reduced error in measuring the magnitude of gravitational acceleration, reduced sensitivity to vibroseismic noise.;4 cl, 2 dwg
