Abstract
An improved three-dimensional position detector and measurement system includes one or more transmitters that each transmit planar light beams and a strobe pulse and a receiver that responds to illumination from the beams and the strobe. The receiver in the system includes calibration logic for executing a quadratic mathematical algorithm to uniquely characterize said planar beams of each of said optical transmitters active in said measurement field. In one embodiment, the quadratic mathematical algorithm uses cones to represent the scan path of the planar beams.
