Abstract

For determining positions and orientations of mirrors, the mirrors are illuminated with parallel light rays. A first camera is arranged in an image plane onto which an objective images the mirrors. A second camera is arranged in a focal plane of the objective, and a third camera is arranged in an intermediate plane located at distances to both the image and the focal plane. At a same point in time, a first, a second and a third picture are taken with the first, the second and the third camera, respectively. The positions and the orientations of the mirrors are determined from light spots in the first and the second picture, respectively; and which of the orientations belongs to which of the positions is determined by correlating light spots in the third picture with both the light spots in the first and in the second picture.
