US Patent 9377302 Distance finder apparatus and system

The present invention is a distance finder apparatus and system operable to project a laser beam spread in a line across a plane, and to determine the distance between a lens and objects that points of the spread laser beam contacts. The present invention comprises: a rangefinder incorporating an optical plate operable to cause an invisible laser beam to be spread, and a visible laser beam to be scattered, in a line along a plane, and the rangefinder is operable to measure distances at points where beams contact one or more objects; a visible pointer laser; and one or more display units. Locations where the spread beam contacts the one or more objects may be at variant distances, and measurements may be determined at any point along the scattered beam.
