Abstract
A laser tracker for industrial coordinative position determination of a target, wherein the laser tracker at least comprises a control and evaluation unit, a base and a beam directing unit, means for detecting a rotation angle of the beam directing unit relative to the base, and a first optical distance measuring unit having at least a first beam source and a first detection unit. The distance measuring unit and the control and evaluation unit are designed for implementing a first and a second measurement functionality, where at least one element of the distance measuring unit is designed for dual use in the first and in the second measurement functionality. The first measurement functionality is for coordinative position determination of a retroreflective target, and the second measurement functionality is for position determination of a diffusely scattering target.
