ABSTRACT:
A laser tracker includes rotatable structure on which a position detector is disposed. The position detector generates a signal indicating a direction of rotation of the structure so that a beam launched from the structure to a patterned target tracks the patterned target. The laser tracker also includes an optical system that includes a lens and is used to determine the orientation of the patterned target.
