Abstract
A coordinate measurement device sends a first light beam to a target which returns a portion as a second beam. The device includes: first and second motors that direct the first beam to a first direction determined by a first angle of rotation about a first axis and a second angle of rotation about a second axis, the first and second angles of rotation produced by the first and second motors, respectively; first and second angle measuring devices that measure first and second angles of rotation, respectively; a distance meter that measures a first distance from the device to the target based in part on a first portion of the second beam; a processor that provides a 3D coordinate of the target based in part on the first distance and the first and second angles of rotation; and a retractable handle at the device top side.
