An modeling arrangement of an optical beam, comprising: A collimator (12) for receiving light from an optical source, and providing a more collimated output; and An optical plate (14) for receiving the most collimated output, in which the optical plate comprises a two-dimensional array of lenses (18) on an input side (15) and a corresponding two-dimensional lens array (19) on the side opposite exit (16), in which the lenses on the input side each have a focal point on a corresponding lens on the output side, and the lenses on the output side each have a focal point on a corresponding lens on the input side, and on which at least some of the lenses on the output side are inclined with respect to the general plane of the optical plate. |
