Abstract: A laser based coordinate measuring device measures a position of a remote target. The laser based coordinate measuring device includes a stationary portion, a rotatable portion, and at least a first optical fiber. The stationary portion has at least a first laser radiation source and at least a first optical detector, and the rotatable portion is rotatable with respect to the stationary portion. The first optical fiber system, which optically interconnects the first laser radiation source and the first optical detector with an emission end of the first optical fiber system, has the emission end disposed on the rotatable portion. The emission end emits laser radiation to the remote target and receives laser radiation reflected from the remote target with the emission direction of the laser radiation being controlled according to the rotation of the rotatable portion.

Abstract: A device for use in conjunction with a coordinate measuring device, a three-dimensional coordinate measuring system and a method of measuring three-dimensional coordinates are described. The device includes 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. The three-dimensional coordinate measuring system further includes 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.
