<p>Optically communicating from a user to a laser tracker a command to control tracker operation includes providing a rule of correspondence between each of a plurality of commands and temporal patterns; user selecting a first command; projecting a first light from the tracker to a retroreflector; reflecting a second light from the retroreflector that is part of the first light; obtaining first sensed data by sensing a third light imaged onto a photosensitive array that is part of the second light; user creating, between first and second times, a first temporal pattern including at least a decrease in the third light's optical power followed by an increase in its optical power, the first temporal pattern corresponding to the first command; 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 tracker.</p> |
