Abstract: A system for calibrating a waveguide-based holographic head-up display that projects images upon a windscreen of a vehicle including a light-diffusing panel positioned at a center of an eyellipse to reflect the images projected by the waveguide-based holographic head-up display. An eyebox of the waveguide-based holographic head-up display is positioned at the center of an eyellipse, and the eyebox is divided into a plurality of unit exit pupils. The system also includes a camera positioned to capture the images reflected by the light-diffusing panel and one or more controllers in electronic communication with the waveguide-based holographic head-up display and the camera. The one or more controllers execute instructions to determine a warp map based on a plurality of corrected individual calibration patterns.

Abstract: A holographic display system for a motor vehicle includes a coherent light source for generating a beam of coherent light and a spatial light modulator (SLM) having a two-dimensional pixel array, which is encoded with a hologram for modulating a phase of the coherent light. The SLM generates a first diffracted beam associated with a main image and a second diffracted beam associated with a conjugate image, where the first and second diffracted beams are angularly spaced from one another by a first angle. The system further includes an optical component for angularly spacing the first and second diffracted beams from one another by a second angle that is larger than the first angle. The system further includes a display surface receiving the first diffracted beam from the optical component to display the main image, with the display surface being free of the second diffracted beam.
