摘要： An optical light engine includes a pair of lenticular microlenslet arrays (MLAs) located on each side of a polarization converter. Non-polarized light from a source in the engine is focused by the first MLA onto cells of the polarization converter which converts the light to a common state of polarization to increase efficiency and improve contrast in the system. A half wave retarder is included on the polarization converter to change the polarization of any light that is reflected from downstream optical components to match that of the forward propagating light. The second MLA, which includes a relatively large number of microlenslet elements, collects the light from the polarization converter and homogenizes the light to be highly uniform when received at a downstream imaging panel in the light engine such as a liquid crystal on silicon (LCOS) panel.

摘要： Introduced here is a display device that comprises a light emitter and a diffractive optical element (DOE) that is optically coupled to receive light from the light emitter and to convey the light along an optical path. The DOE may have an input surface and an output surface parallel to the input surface, where the input surface and the output surface each have a central region and a peripheral region. The DOE further may have optical characteristics such that light exiting the DOE in the peripheral region of the output surface has greater brightness than light exiting the DOE in the central region of the output surface.

摘要： An apparatus for use in replicating an image associated with an input-pupil to an output-pupil includes a planar optical waveguide including a bulk-substrate, and also including an input-coupler, an intermediate-component and an output-coupler. The input-coupler couples light corresponding to the image into the bulk-substrate and towards the intermediate-component. The intermediate-component performs horizontal or vertical pupil expansion and directs the light corresponding to the image towards the output-coupler. The output-coupler performs the other one of horizontal or vertical pupil expansion and couples light corresponding to the image, which travels from the input-coupler to the output-coupler, out of the waveguide. The apparatus further includes an adjacent planar optical component to provide a more uniform intensity distribution compared to if the adjacent planar optical component were absent.

摘要： The technology provides decoupling an aspheric optical element from a birdbath optical element in a near-eye display (NED) device. One or more aspheric lens are used with a spherical birdbath reflective mirror in a projection light engine of a NED device. 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).

摘要： A light source combines colored light from different LED sources to provide white light output. Multiple LEDs emitting light at different peak wavelengths may be disposed on a flexible substrate, the LEDs being close to an aperture formed in the substrate. Multiple mirrors, including at least one dichroic mirror, are oriented to reflect light from the multiple LEDs into the aperture. The flexible substrate includes a dielectric layer having a cavity region and an adjacent neighboring region that is thicker than the cavity region. The aperture and the multiple LEDs are all disposed in the cavity region of the dielectric layer. An integrating rod may be coupled to the aperture to receive the reflected light from the multiple LEDs.

摘要： Optical elements, color combiners using the optical elements, and image projectors using the color combiners are described. The optical elements can be configured as color combiners that receive different wavelength spectrums of light and produce a combined light output that includes the different wavelength spectrums of light. In one aspect, the received light inputs are unpolarized, and the combined light output is polarized in a desired state. In one aspect, the received light inputs are unpolarized, and the combined light output is also unpolarized. The optical elements are configured to minimize the passage of light which may be damaging to wave-length-sensitive components in the light combiner. Image projectors using the color combiners can include imaging modules that operate by reflecting or transmitting polarized light.

摘要： In a near-eye or heads-up display system including a display engine and an optical waveguide, a quarter-wave retarder (QWR) is positioned between a polarizing beam splitter (PBS) of the display engine and an input diffraction grating of the waveguide. Additionally, a linear polarizer can be positioned between the PBS and the QWR. Light corresponding to an image generated by a reflective microdisplay of the display engine is diffracted into the waveguide by the input diffraction grating, so it can travel by way of total internal reflection to an output coupler and viewed by a human eye. The QWR alone, or in combination with the linear polarizer, prevents a ghost image that may otherwise occur if a portion of the light corresponding to the image, that is diffracted into the waveguide by the input diffraction grating, is diffractively out-coupled by the input diffraction grating and thereafter reflects off the reflective microdisplay.
