FIELD: measuring equipment.SUBSTANCE: laser range-finder comprises a pulsed semiconductor laser, an optical system, a clock pulse generator, pulse counter, a device with an indicator, a key circuit, a photodetector, a delay line, a coincidence circuit. Also rangefinder comprises an adder and an image rotation device providing image rotation - prism Dove - emitting area pulsed semiconductor laser so that two flat shape figures, symmetric relative to centre, and boundaries of each figure formed by an oval in a plane perpendicular to line of sight, alternately formed, long axis perpendicular to symmetry of two figures.EFFECT: technical result consists in improvement of accuracy of measurements.1 cl, 3 dwg |
