Device for producing a polychromatic holographic image in a seat trim panel

A device for creating a polychromatic holographic image, comprising

• a. a light guide comprising a first input coupling region and a second input coupling region for input coupling light into the light guide,
• b. a first light source designed to radiate light of a first wavelength range into the first input coupling region;
• c. a second light source designed to radiate light of a second wavelength range into the second input coupling region;
• d. a holographic structure for creating the polychromatic holographic image under illumination by means of the first and second light sources;
• wherein
• the holographic structure has a first region, which is wavelength-selective for light of the first wavelength range, and a second region, which is wavelength-selective for light of the second wavelength range, and wherein the light guide is configured to guide the light from the first light source to the first region of the holographic structure and the light from the second light source to the second region of the holographic structure.
