Holographic Waveguided See-Through Display

To address the NASA need for lightweight, space suit-mounted displays, Luminit proposes a novel Holographic Waveguided See-Through Display. Our proposed Holographic Waveguided See-Through Display (HoWSD) will integrate highly selective waveguiding Bragg holograms, Luminit diffuser technology, a unique LCD backlight into a helmet-mounted display (HMD) that will provide easy- to-access clearly visible information to astronauts during extravehicular activity (EVA). The proposed HoWSD incorporates a unique design and Luminit novel diffusers into a functional HMD, which enables us to meet NASA goals for a functional, unobtrusive display device that provides information to astronauts during EVA. HoWSD offers a compact, low-profile display with high brightness and contrast, which is fully see-through and high resolution. In Phase I Luminit will demonstrate the feasibility of a see-through helmet-mounted display that can operate under various illumination levels, and which will prepare us for Phase II. In Phase II, Luminit plans to develop a fully-functional rugged prototype and demonstrate HoWSD functionality. The demonstrated results will offer NASA the capability of incorporating a non-obtrusive, rugged, wide field-of-view display into a space suit helmet designed for EVAs.
