LASER RANGE-FINDER Russian patent published in 2007 - IPC G01C3/08 

FIELD: optic-electronic tool-making, in particular - impulse laser range-finders.

SUBSTANCE: laser range-finder contains transmitting channel, comprising optically connected laser and transmitting optical system, and sighting-receiving channel, comprising objective, first spectrum divider, device for observation of objects image with target mark, photo-detection device, second spectrum divider, test-object, system for lighting test-object, and light reflector, mounted in front of the objective with possible movement of its input eye to the zone. For operative checking of sighting and receiving channels, laser range finder additionally contains optical compensator, positioned on optical axis of objective between first and second spectrum dividers. Photo-receiving device is optically engaged by means of first spectrum divider with device for observation of objects image. Second spectrum divider is positioned between first spectrum divider and photo-receiving device on optical axis of objective at an angle to it. Test-object is positioned on optical axis of objective and connected to it optically by means of second and first spectrum dividers.

EFFECT: increased precision when measuring target distance.
