Claim Text:
1. A coordinate measurement device comprising: a housing; a first motor operably coupled to the housing, the first motor rotating about a first axis; a second motor operably coupled to rotate the housing, the second motor rotating about a second axis; a mirror coupled to the first motor and rotate about the first axis, the first motor and the second motor being positioned such that an intersection of the first axis and the second axis lies on the mirror, the intersection of the first axis and the second axis defining a device frame of reference; a first angle measuring device that measures a first angle of rotation and a second angle measuring device that measures a second angle of rotation; a 3D time-of-flight (TOF) camera arranged within the housing, the TOF camera being arranged coaxially with the first axis, the 3D TOF camera oriented to acquire an image of an object reflected from the mirror; and a processor configured to determine at least one first three-dimensional (3D) coordinate in the device frame of reference of at least one point on the object, the at least one first 3D coordinate based at least in part on the image acquired by the 3D TOF camera, the first angle of rotation, and the second angle of rotation.
