Abstract
A method for measuring the range to multiple points on a surface by projecting a line of light onto the surface, imaging said line of light onto a photodetector, computing the centroid of said line of light, computing quality factors for each computed centroid and encoding the quality factors as one or more bits in the centroid value, transmitting said centroid value to a data receiver, and computing the range to the surface for each point corresponding to each centroid value.
