摘要
In a laser tracking system equipped for interferometric distance measurement there are provided at least two retroreflectors (3.1, 3.2, 3.3) which are connected to the target tracking mirror (1) in a manner such that their position changes when the spatial orientation of the target tracking mirror (1) is changed. Secondary measurement beams (4.1, 4.2, 4.3) deflected out of the primary measuring beam (4) of the laser tracking system are directed onto the retroreflectors (3.1, 3.2, 3.3.). Path length changes in the beam path of the secondary measurement beams (4.1, 4.2, 4.3) are interferometrically measured and the readings are used for computing the spatial orientation of the target tracking mirror (1).
