1. A noncontact position and orientation measurement system comprising:

  • at least four beacons disposed on a first object, each beacon operable to generate an optical signal;

    a beacon controller operable to activate and deactivate each of the beacons;

    an electro-optical sensor disposed on a second object and operable to generate an output signal for each optical signal received from the beacons; and

    a signal controller coupled to the electro-optical sensor and operable to determine a position and an orientation of the second object relative to the first object using the output signals generated by the electro-optical sensor, the signal controller further operable to, in response to a received optical signal, adaptively control a sequence of beacon activation and deactivation.
