FIELD: measurement technology. SUBSTANCE: proposed device has source of coherent radiation, mechanical converter, optical unit of reflectors and beam splitter and monitor. Mechanical converter is manufactured in the form of friction transmission composed of driving wheel which rotation axis is attached to object and two driven discs which rotation axes are located on straight line parallel to normal to plane of beam splitter. One reflector is put on each driven disc, they are optically coupled to beam splitter mounted on holder. EFFECT: increased authenticity of check thanks to simplified adjustment of elements of optical unit of device. 1 dwgh
