摘要
A multi-dimensional measuring system is disclosed wherein a laser-based tracking unit communicates with an optical target on a measurement instrument to obtain position and orientation information about the instrument. The optical target incorporates a plurality of encoders configured to provide a full 360° working range in pitch, yaw and roll. Full working range in pitch and yaw is achieved through the use of a pitch/yaw angular encoder. Full 360° working range in roll is achieved with a combination of a level sensor and a 360° angular encoder, which are fixed to a pendulum so that the level sensor is always aligned to gravity. Use of a slip-ring mechanism ensures the unlimited full working range in roll. The measurement instrument includes a scanner integrated with a probe receptacle adapted to accept a probe assembly to provide the instrument with both a scanning measurement and a probe measurement capabilities. Incorporation of an additional probe receptacle provides increased measurement capability and flexibility. The optical target with its full 360° angular working range in pitch, yaw and roll can be utilized independently of the measurement instrument. In combination with a laser tracker, the optical target can be attached to any object or surface to be measured, or alternatively, it can be attached to a movable device and the position of that device monitored.
