Abstract: A method for producing a decorative element and uses of a decorative element. A polarizing layer functioning as an analyzer is applied to a transparent optical carrier material and a transparent optical functional layer is applied as an image-forming layer including an optically anisotropic material. By spatially structuring the functional layer, a targeted location-dependent dependency of material properties of the optically anisotropic material is created for producing the image-forming layer. One or several decorative elements produced can each be introduced into a light field of a lighting device in a desired shape, size and quantity and having settable image motifs (image structures) and being disposed at different spatial distances and being freely disposable. The decorative element produced is intended to be used as an architectural element for creating light-optical effects in the exterior area of buildings, as a design element for interior design or for object design.

Abstract: The invention relates to a method for producing a decorative element DE and uses of a decorative element DE produced in this way.
A polarizing layer PS which functions as an analyzer is applied to a transparent optical carrier material TM and a transparent optical functional layer FS is applied to the other side as an image-forming layer BS which consists of an optically anisotropic material OAM.
By spatially structuring the functional layer FS in an image-forming manner, a targeted location-dependent dependency of material properties of the optically anisotropic material OAM is created for producing the image-forming layer BS in the form of an image motif BM.
One or several decorative elements DE produced according to the invention can each be introduced into a light field of a lighting device BV in a desired shape, size and quantity and having settable image motifs BM (image structures) and being disposed at different spatial distances and being freely disposable.
Furthermore, in terms of a device, the decorative element produced according to the invention is intended to be used as an architectural element for creating light-optical effects in the exterior area of buildings, as a design element for interior design or for object design.

Abstract: A system (02) is provided with a projection device (01) comprising a light source (03) and an information imprinting device (08) and at least one projection surface (05, 07). The at least one projection surface (05) may have a sectionally phase-maintaining surface. At least one filtering device (11) is arranged between the projection surface (05) and an observation point (15) or a filtering device (09) is arranged independently of the at least one projection surface between an output of the information imprinting device (08) of the projection device (01) and the projection surface (05, 07), wherein the phase modulation is converted into an amplitude modulation by means of the filtering device. Usage of such a system for multistage elective display of information on at least one projection surface (07, 09) is also proposed.
