Abstract
A self-compensating laser tracker may include a frame assembly including a laser, and at least two-embedded, non-moveable, reflecting members; and a rotatable mirror. The laser and the mirror are arranged such that a laser beam emitted from the laser may be reflected by the mirror. One of the at least two reflecting members may be a cube corner retroreflector and a second of the at least two reflecting members may be a frame assembly mirror. The cube corner retroreflector and the frame assembly mirror may be fixed in position on the frame assembly relative to the rotatable payload and relative to each other, and are structured to reflect the laser beam in a frontsight mode and a backsight mode.
