Abstract (en)
[origin: EP2239150A1] The device has three-dimensional diffractive surface elements (18) arranged on an upper surface (14) of a flat light reflection element (10) for deflecting light reflected on the light reflection element in a direction of an observer and/or an examination device. The diffractive surface elements comprise a diffraction grating on a light outlet surface. The diffraction gratings of the diffractive surface elements are designed and/or arranged such that an asterism is produced for the observer and/or examination device.
