Abstract
The invention relates to a wavefront forming device (2), especially for a holographic reproduction, comprising an arrangement of mirror elements (3). Said mirror elements (3) each comprise at least one actuator (4). The respective actuator axially tilts and/or displaces the respective mirror element (3) in at least one direction. The mirror elements (3) are arranged in such a way that a wavefront (W) is directly formed by the actuation of the mirror elements (3).
