Abstract
A method for optically communicating, from a user to a laser tracker, a command to direct a light beam from the tracker to a retroreflector and lock onto the retroreflector includes projecting a first light to the retroreflector. Also, moving by the user the retroreflector in a predefined spatial pattern which corresponds to the command; reflecting a second light from the retroreflector, the second light being a portion of the first light; obtaining first sensed data by sensing a third light which is a portion of the second light and imaging the third light onto a photosensitive array on the tracker and converting the third light on the photosensitive array into digital form. Further, determining the first sensed data corresponds to the predefined spatial pattern; pointing the light beam from the tracker to the retroreflector; and locking onto the retroreflector with the tracker light beam.
