Abstract
A holographic optical element (HOE). The HOE includes a hologram, and an electroactive polymer (EAP), in particular a dielectric elastomer actuator (DEA). The electroactive polymer includes at least one elastomer layer, in particular an elastomer film, arranged between two electrodes, and the hologram is applied to an electrode of the electroactive polymer. The hologram or a holographic function which can be provided by means of the hologram, and in particular diffraction properties of the hologram, can be adapted by means of a controllable deformation of the electroactive polymer. A method for producing such a holographic optical element is also described.
