title = "Method for large field of view and eye-box for holographic waveguide display based on LED illumination",
abstract = "Holographic waveguide display takes the advantage of pupil expansion to increase the size of eye-box which can be widely employed into augmented reality (AR) systems. However, the angular selectivity of holographic optical elements (HOEs) used as in- and out-coupler for waveguide display is very limited when reading out by coherent light source like lasers. Here, we propose a method by utilizing broadband light source like LED with multilayer HOEs or multilayer waveguides, each pair of the in- and out-coupling HOEs or waveguides will be angularly separated to construct the specific angular region. Due to its decent spectrum selectivity of holographic couplers and multilayer structure, the field of view (FOV) of the display system can be significantly increased. Large eye-box is realized by employing pupil expansion for allowing the image to interact with out-couplers multiple times.",
