Abstract

Car manufacturers are strongly interested in optical systems producing the perception of an aerial 3D image. Such an effect can be obtained using surface relief computer-generated holograms (CGH). However, classical single light source illumination methods of holograms by a plane wave or spherical wave generally requires long optical path systems that are too bulky to easily fit in a car. In this article, we propose a method to design CGHs that are compatible with multi- LED illumination system while generating convincing 3D aerial images. We also demonstrate an experimental realization of a prototype of a holographic system through the fabrication of a hologram illuminated simultaneously by 6 separate LEDs.
