Abstract
Embodiments include systems and methods for operating a head-up display for a vehicle. Embodiments include a first light engine, a second light engine, at least one waveguide, an eye-box for a viewer, and a light detector. The first light engine is arranged to form a first wavefront (e.g., a first holographic wavefront) formed by illuminating a first hologram of a picture, and the second light engine is arranged to form a second wavefront. The waveguide includes an input, pair of opposing reflective surfaces, and an output. The input is arranged to receive the first and second holographic wavefronts. The pair of opposing reflective surfaces is arranged to waveguide the first holographic wavefront and second wavefront therebetween by internal reflection. A first surface of the pair of opposing reflective surfaces is partially transmissive thereby forming an output port for a plurality of replicas of the first and second holographic wavefronts.
