1. An optical transmitter for use in a position measurement system that generates x-y-z data within a measurement field, said system including means for calculating the x-y-z data at any point in the measurement field using beams from a plurality of rotatably supported optical transmitters, the optical transmitter comprising:

  • at least one optical source that generates at least one rotating substantially fan shaped beam;

    a strobe that generates a strobe pulse at a predetermined point in the rotation of said at least one fan shaped beam;

    a memory, disposed in said optical transmitter, containing calibration data unique to said transmitter, said calibration data defining a relative position of the fan beams generated by the optical transmitter; and

    an output port for outputting the calibration data to identify the transmitter.
