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.
