1. A laser metrology system for determining a location of a target, comprising:
- a laser projector having a laser source for projecting a laser beam and a rotating head directing the laser beam in a lateral direction,a sensor associated with said laser projector and being capable sensing the laser beam;
a reflective target configured to reflect the laser beam projected from said laser source toward said sensor in a manner indicative of an angle of said rotating head and pulse of said laser beam thereby determining the location of the target.

Abstract
A laser metrology system for determining a location of a target utilizes a laser projector having a laser source for projecting a laser beam. A rotating head directs the laser beam in a lateral direction. A sensor associated with the laser projector is capable of sensing the laser beam. A reflective target is configured to reflect the laser beam projector from the laser source toward the sensor in a manner indicative of the angle of the rotating head and the pulse of the laser beam to determine location of the target.

12. A method of determining a position of a target, comprising the steps of:
-
providing a source of a projected laser beam, a sensor and head for directing said laser beam; generating a projected laser beam from said source; directing said laser beam through said head in a lateral direction toward a target; and said target reflecting a reflected laser beam toward said sensor in a manner indicative of at least one of an elevational, horizontal angular orientation and other geometric constraint of said target relative to said sensor;
said sensor signaling a computer the angular orientation of said target relative to said sensor and said computer determining the location of said target from said angular orientation of said target relative to said sensor. - View Dependent Claims (13, 14, 15, 16, 17, 18)
