Optical aperture expansion arrangement for near-eye displays
An optical aperture expansion arrangement particularly useful for near-eye displays employs a waveguide (30, 140, 145) with wedge configurations (25, 26) to generate two modes of propagation of image illumination along the waveguide, and to couple out both modes from the waveguide. Various embodimen...

| description | An optical aperture expansion arrangement particularly useful for near-eye displays employs a waveguide (30, 140, 145) with wedge configurations (25, 26) to generate two modes of propagation of image illumination along the waveguide, and to couple out both modes from the waveguide. Various embodiments employ rectangular waveguides within which the image illumination propagates by four-fold internal reflection. In some cases, the wedge configurations are combined with an array of partially-reflective internal surfaces (45, 150) to achieve two-dimensional aperture expansion. |
