Abstract: An apparatus for shaping the output beam of a strip of lasers, or an array of such strips, comprising a first reflective member including at least a first reflective element for deflecting a first portion of the output beam in a first direction oriented at a first angle in the slow axis direction and at a second angle in the fast axis direction, and at least a second reflective member including at least a first reflective element for deflecting the first output beam portion from the first direction to a second direction in the Z axis. The output beam is thus shaped to define at least two beams comprising at least the first portion and a remainder of the output beam which is propagated along the Z axis without deflection by any reflective member, with the first portion of the output beam being oriented approximately parallel to the un-deflected remainder.

Abstract: A method for three-dimensional display in which a plurality of individual image elements ?ij are made visible simultaneously in a raster of columns i and lines j, wherein the image elements ?ij reproduce partial information from a plurality of views Ak (k1 . . . n) of a scene/object, and adjacent image elements ?ij radiate light of different wavelengths or wavelength regions is provided. In a method of the type described above, wavelength-dependent propagation directions are predetermined for the light radiated from the image elements ?ij. The propagation directions within an observation space in which an observer is situated intersect in a plurality of intersection points which correspond to observation positions. From each observation position, one eye of an observer perceives predominantly partial information of a first selection and the other eye perceives predominantly partial information of a second selection from views Ak (k=1 . . . n).
