Abstract: The invention concerns an optical security element and a process for the production of an optical security element in the form of a multilayer body having a projection element (8) in a first region of the security element for converting light transmitted through the optical security element in the first region by means of diffraction. The projection element (8) has a plurality of first zones (85) in which a first surface of a replication layer (82) has a first surface structure and an opaque metallic layer (85) is arranged on the first surface of the replication layer (82). It further has a plurality of transparent second zones (86) in which the first surface of the replication layer has a second surface structure (87) with an aspect ratio differing from the aspect ratio of the first surface structure and no opaque metallic layer is provided. The first zones (85) each have a smallest dimension of less than 20 μm and the pattern formed from the first and second zones forms a diffractive optical system which diffracts the light transmitted through the second zones (86) to represent a first item of information.

Abstract: Light modulator displays may be illuminated using a light guide comprising diffractive optics that directs light onto the light modulators. The light guide may comprise, for example, a holographic light turning element that turns light propagating within the light guide onto the array of light modulators. In some embodiments, the holographic element has multiple holographic functions. For example, the holographic element may additionally collimate ambient light or diffuse light reflected form the light modulators.

Abstract: A holographic lighting apparatus includes at least two channels for the respective associated lighting functions. Each channel includes an edge-lit arrangement with an incoupling surface for coupling light from a light source into the arrangement, and an outcoupling surface; and a light source. The edge-lit arrangements of the channels are all included in a monolithic component having a common outcoupling surface, and each channel is arranged so as to be rotated about a surface normal of the outcoupling surface along an azimuthal arrangement angle. The component has at least one holographic structure for generating the lighting function of the relevant channel when said structure is illuminated by the light source of the channel. Also provided are a vehicle including a corresponding lighting apparatus, the use of the lighting apparatus as a display in a vehicle, and the lighting apparatus as an LED collimator.

Abstract: The invention concerns a multi-layer body (7) having a carrier substrate (750) and a transparent layer (720) at least partially arranged in a window (70) or in a transparent region of the carrier substrate (750). The transparent layer (720) has at least a first subregion (71a) and a second subregion (71b) with a varying refractive index, which are arranged in mutually juxtaposed relationship in the layer plane defined by the transparent layer (720), and are at least partially arranged in the window (70) or in the transparent region of the carrier substrate (750). Each of the subregions (71a, 71b) has a plurality of periodically arranged nodes which form an optical-action element and which are formed by a refractive index variation and which are arranged in substantially mutually parallel planes. The planes in the at least first subregion (71a) are not parallel to the planes in the at least second subregion (71b). At least in one of the subregions (71a, 71b) the planes extend neither parallel nor perpendicular to the layer plane. In that way both the light incident on the front side and on the rear side of the multi-layer body (7) is diffracted by the optical-action elements and the elements produce an optical effect which is different in the front view and in the rear view in the incident light mode.
