The invention relates to a sweet spot unit which focuses light at predeterminable regions in space in sweet spots by at least one flat controllable optical matrix and an optical mask. Sweet spots designate the zones of autostereoscopic viewing that are free of cross-talking. The unit comprises a controllable optical matrix (BM) with a multitude of controllable and regularly arranged pixels, and an optical mask (LM*), which is tolerance-loaded due to manufacture or other influences, with projection elements (L 1*, L 2*, . . . ), whereby along a section along any line pixels of this line are assigned to the projection elements (L 1*, L 2*, . . . ), said pixels being projected to any predetermined sweet spots by projection elements, characterized by that those pixels assigned to the projection elements are activated by program means that are congruently projected into the predetermined sweet spots.
