An instrument panel for a motor vehicle is provided. The instrument panel includes an instrument panel surface and a plurality of indicia disposed on the instrument panel surface. The plurality of indicia comprises holographic ink.

An image display according to an embodiment includes a first image-displaying portion that displays first information about a certain object as a first image of object color, and a second image-displaying portion that displays second information about the object as a second image of structural color provided by a relief structure, the relief structure including at least one structure selected from the group consisting of diffraction grating, hologram, and light-scattering structure having an anisotropic light-scattering property. According to an example, the object is a person, and the first image includes a facial image of the person. A labeled article according to another embodiment includes the image display, and a substrate supporting the image display.

The present disclosure relates to apparatuses and methods for performing in-line lens-free digital holography of objects. At least one embodiment relates to an apparatus for performing in-line lens-free digital holography of an object. The apparatus includes a point light source adapted for emitting coherent light. The apparatus also includes an image sensing device adapted and arranged for recording interference patterns resulting from interference from light waves directly originating from the point light source and object light waves. The object light waves originate from light waves from the point light source that are scattered or reflected by the object. The image sensing device comprises a plurality of pixels. The point light source comprises a broad wavelength spectrum light source and a pinhole structure. The image sensing device comprises a respective narrow band wavelength filter positioned above each pixel that filters within a broad wavelength spectrum of the point light source.
