Abstract:
A mixed reality direct retinal projector system that may include a headset that uses a reflective holographic combiner to direct light from a light engine into an eye box corresponding to a user's eye. The light engine may include light sources coupled to projectors that independently project light to the holographic combiner from different projection points. The light sources may be in a unit separate from the headset that may be carried on a user's hip, or otherwise carried or worn separately from the headset. Each projector may include a collimating and focusing element, an active focusing element, and a two-axis scanning mirror to project light from a respective light source to the holographic combiner. The holographic combiner may be recorded with a series of point to point holograms; each projector interacts with multiple holograms to project light onto multiple locations in the eye box.
