ALIGNMENT-INSENSITIVE IMAGE INPUT COUPLING

摘要

Various embodiments are disclosed herein that relate to coupling light into waveguides in a near-eye display device in a manner configured to be tolerant to misalignment of the waveguides with each other and/or other optics. For example, one disclosed embodiment provides a near-eye display device comprising one or more waveguides, wherein each waveguide comprises a light input coupling configured to receive light at a first side of the waveguide to couple the light into the waveguide, and a light output coupling configured to emit light from the waveguide at a second side of the waveguide, the second side of the waveguide being opposite the first side of the waveguide.
