Abstract:

Subject of research. Analysis of construction schemes, modeling, and experimental recording of asymmetric holographic waveguide devices for multiplying the exit pupil of augmented reality displays. The purpose of the work. Analysis of existing and identification of new asymmetric waveguide element designs and diffraction modes that provide an increase in the angular field or improved energy efficiency of display systems. Method. The main experimental methods used were holographic recording and the study of waveguide diffraction modes on relief-phase and Bragg diffraction gratings. Computer simulations of the waveguide diffraction gratings under consideration were also used, and the results of ray tracing were compared with the experimental results. Several options for building waveguide diffractive periscopes for original augmented reality display schemes have been analyzed. Main results. It has been determined that the inclined position of a waveguide diffractive periscope can significantly increase the angular field of the virtual image (up to 2,2 times). The mode of unidirectional ray multiplication was described. A new application of the two-ray input mode in holographic waveguide periscope systems with a horizontally elongated angular field of view is discovered. Practical significance. The created experimental samples of augmented reality displays and their computer models showed good matching and can be applied for creating working prototypes and organizing of augmented reality displays mass production.
