1. A three-dimensional coordinate measuring system, comprising:

  • a light source mounted substantially within the center of a spherical member having a spherical surface configured such that the distance from the light source to the outer contact surface of the sphere is substantially equal to the radius of the sphere regardless of sphere orientation; and

    a coordinate-measuring device, the coordinate-measuring device configured to track the movement of the light source and to measure either azithmuth angles and zenith angles, or to spherically encode tracking information related to relevant positions of the light source.
