Holographic Combiners Improve Head-Up Displays Mar 18, 2019 — Combiners are semitransparent surfaces used in head-up display (HUD) and augmented reality (AR) systems to overlay an image presented by a projector on top of the viewer’s physical world. The combiner is transparent and lets the viewer see through it, while simultaneously reflecting dynamic digital information. Over the years, combiners have evolved from simple semitransparent flat surfaces that passively reflected light from projectors to sophisticated conformational holograms that
