Read Abstract +

Digital augmentation of direct view optics like riflescopes allows viewing of the scene with near-zero latency while simultaneously offering increased situational awareness from fielded sensors and systems data. Existing solutions to digitally augment a direct view optic add a considerable amount of weight/size, require the digital projection system to be designed into each specific viewing optic, or interfere with operational function of the optic. Here we present an externally mounted, compact optical waveguide capable of displaying information such as ballistic data overlaid onto the field-of-view of a riflescope. Volume phase holograms form the input/output couplers and the pupil expander of the waveguide. The holographic waveguide satisfies the contrast ratio needed for daylight bright environments, allows for operability of the diopter adjustment, minimally impacts eye relief, and requires no refocusing to view the symbology.
