A projection light engine provides image light (or other information), by way of the spherical birdbath reflective mirror and at least one aspheric lens, to a near-eye display of the NED device. The spherical birdbath reflective mirror collimates and reflects the image light to an exit pupil external to the projection light engine. Decoupling the aspheric optical element from the spherical birdbath reflective mirror may enable high modulation transfer function (MTF) and improved manufacturability of the projection light engine. The NED device having aspheric optical elements decoupled from a birdbath optical element may be positioned by a support structure in a head-mounted display (HMD) or head-up display (HUD). | 02-11-2016 |
20160077338 | Compact Projection Light Engine For A Diffractive Waveguide Display - The technology provides a waveguide display having a compact projection light engine and a diffractive waveguide. The diffractive waveguide includes input diffraction gratings with rolled k-vectors. The projection light engine provides collimating light to a projected exit pupil external to the diffractive waveguide. The projection light engine components may include a light (or illuminating) source, microdisplay, lenticular screen, doublet, polarizing beam splitter (PBS), clean-up polarizer, fold mirror, curved reflector and quarter waveplate. A method of manufacturing a diffractive waveguide includes providing input gratings with rolled k-vectors. Rays of light are diffracted by, and passed through, a master hologram to form input diffraction gratings of a copy substrate. A second copy substrate may likewise be formed with a different master hologram. Multiple copy substrates may be assembled to form a multi-layer diffractive waveguide (or multiple diffractive waveguides) having input diffraction gratings with increased diffraction efficiency and angular bandwidth. | 03-17-2016 |
20160097930 | MICRODISPLAY OPTICAL SYSTEM HAVING TWO MICROLENS ARRAYS - The technology provides an optical system for converting a source of projected light to uniform light for a liquid crystal on silicon microdisplay in a confined space, such as in a near-eye display device. The optical system may include a first microlens array, a second microlens array, and a polarizer device disposed between the first microlens array and the second microlens array. The near-eye display device having first and second microlens arrays may be positioned by a support structure in a head-mounted display or head-up display. | 04-07-2016 |
