FIELD: physics.
SUBSTANCE: hologram ballistic gravimeter comprising a vacuum chamber, a device dropping the trial body, the first hologram attached to the trial body, a monochromatic radiation source, a collimation system, a photodetector, an electronic device of synchronization and signal processing. On the light beam that has passed the first hologram, the second hologram is set geometrically identical to the first. The photodetector is installed in the light beam overlapping area diffracted at both holograms.
EFFECT: decreasing the gravimeter size.
