Abstract

The purpose of the study is development of the wide field of view waveguide-based augmented reality system. For solving the issue, we examined the influence of curving and wedging of the waveguide on the field of view in augmented reality systems. We applied the known Q_U ray tracing method for calculation of the field of view in shaped waveguide-based systems and examined the image transferring through such systems. We found that shaped waveguide can transfer significantly wider field of view than planar waveguide. However, the image redirection can not be performed by standard techniques for light coupling. Consequently, we propose the 73° field of view waveguide-based system that consist of pico-projector, as image source, shaped waveguide for image transferring and holographic combiner for beams redirection to the eye pupil. The system represent a compact solution with wide field of view for integration in augmented reality devices.
