Scope of research. Waveguide holographic optical elements for large-size Augmented Reality displays design, it’s characteristics and recording schemes. The purpose. Modeling, development and production of test samples of waveguide holographic periscopes for large-scale Augmented Reality systems. Method. Computer modeling of waveguide diffraction gratings and holographic recording of large-size holographic gratings were used as the main methods. At first, studies and comparisons of several types of waveguide multiplexers of the exit pupil of augmented reality displays were carried out. Then, the recording of large-sized waveguide diffraction gratings - the basis of waveguide holographic multiplexers of the exit pupil was performed. The main results. Original software for modeling waveguide holographic periscopes has been developed, known schemes have been studied, and an original, more optimal configuration has been proposed. Schemes for recording large-sized (up to 300ґ250 mm) waveguide holographic periscopes and their copying have been developed. The experimental model of the Head-Up Display has been developed, based on large-size waveguide diffraction periscopes. It has significantly smaller dimensions and weight in comparison with known examples of classical systems (the weight of the model is less than 5 kg). The Head-Up Display parameters achieved: eye relief up to 900 mm, large exit pupil up to 250ґ300 mm, angular field of view up to 25° diagonally, operation with a standard incoherent projection system in the spectral range of 510–540 nm. Practical significance. The developed model of Head-Up Display is a working prototype of an augmented reality display for vehicles, which is distinguished by significantly smaller dimensions and weight with high optical characteristics. The possibility of its mass production is shown.
