LASER LEVEL METER Russian patent published in 2000 - IPC

FIELD: surveyor, geodesic and optical instruments. SUBSTANCE: device may be used for measuring distances, azimuths, heights, to be detected by means of trigonometric leveling, as well as for high-precision angular measurements. Device has mechanism for orientation of laser reference beam in space, serial optical circuit of reference laser light beam source, which is mounted in housing, light separator, which is mounted for separation of reference light beam in horizontal plane, and reflector. In addition, reference laser light source and light separator are located on main optical axis. Said light separator is mounted for separation of reference light beam in horizontal plane. Reflector is mounted for setting angular rotation in vertical plane as well as for free passing of light beam from laser source. EFFECT: increased precision of measurements, increased stability of three- dimensional position of laser beam in vertical and horizontal planes. 13 cl, 3 dwg
