摘要： 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.

摘要： A method for optically communicating, from a user to a laser tracker, a command to control operation of the laser tracker includes steps of providing a rule of correspondence between each of a plurality of commands and each of a plurality of spatial patterns, and selecting by the user a first command from among the plurality of commands. The method further includes the steps of moving by the user, between a first time and a second time, a retroreflector in a first spatial pattern from among the plurality of spatial patterns, wherein the first spatial pattern corresponds to the first command, and projecting a first light from the laser tracker to the retroreflector. The method also includes the steps of reflecting a second light from the retroreflector, the second light being a portion of the first light, and obtaining first sensed data by sensing a third light, the third light being a portion of the second light, wherein the first sensed data is obtained by the laser tracker between the first time and the second time. The method includes also the steps of determining the first command based at least in part on processing the first sensed data according to the rule of correspondence, and executing the first command with the laser tracker.
