Method for detecting the spatial position of a tracking mirror and mirror arrangement for carrying out said method

(57) In the laser tracking system which it had for the range finding by a summary interferometer, When for a target pursuit mirror (1) spatial changes, at least two reverse reflectors (3.1, 3.2, 3.3) connected to a target pursuit mirror (1) in a mode which changes the position are prepared. The secondary measurement beam (4.1, 4.2, 4.3) deflected from the primary measurement beam (4) of a laser tracking system is oriented on a reverse reflector (3.1, 3.2, 3.3). Course length change of the beam course of a secondary measurement beam (4.1, 4.2, 4.3) is measured with an interferometer, and it is used for a reading calculating for a target pursuit mirror (1) spatial.
