Abstract: A transparent holographic diffuser screen that diffracts the light beams of a digital light projector, which focuses a real image in the plane of the aforementioned transparent holographic diffuser screen, which redirects the light to an eyebox at a pre-determined viewing position generating as a set of diffracted diffused beams that can be seen from the eyebox as a flat in-plane image. The transparent holographic diffuser screen may be used to provide either a highest luminance or a largest eyebox. Potential applications include use for automotive applications, which may include applications for displaying videos, playing games, and video conference apps.
