FIELD: measurement equipment.
SUBSTANCE: ballistic gravity meter contains a vacuum chamber, a test body dropping device, a radiation source, a photodetector, a signal synchronisation and processing device. On the test body the optical element is fixed, which is designed as a diffraction lattice. Marks of the named lattice are located horizontally. On the way of the light rays diffracting on a lattice during the device operation the optical multiplexer is installed, the output of which is connected to a photodetector.
EFFECT: increase of time resolution, reduction of dimensions of the device and simplification of algorithm of signal processing.
