Abstract: A wearable display system includes an eyepiece stack having a world side and a user side opposite the world side, wherein during use a user positioned on the user side views displayed images delivered by the system via the eyepiece stack which augment the user's view of the user's environment. The wearable display system also includes an angularly selective film arranged on the world side of the of the eyepiece stack. The angularly selective film includes a polarization adjusting film arranged between pair of linear polarizers. The linear polarizers and polarization adjusting film significantly reduces transmission of visible light incident on the angularly selective film at large angles of incidence without significantly reducing transmission of light incident on the angularly selective film at small angles of incidence.

Abstract: An eyepiece waveguide for an augmented reality display system. The eyepiece waveguide can include an input coupling grating (ICG) region. The ICG region can couple an input beam into the substrate of the eyepiece waveguide as a guided beam. A first combined pupil expander-extractor (CPE) grating region can be formed on or in a surface of the substrate. The first CPE grating region can receive the guided beam, create a first plurality of diffracted beams at a plurality of distributed locations, and out-couple a first plurality of output beams. The eyepiece waveguide can also include a second CPE grating region formed on or in the opposite surface of the substrate. The second CPE grating region can receive the guided beam, create a second plurality of diffracted beams at a plurality of distributed locations, and out-couple a second plurality of output beams.

Abstract: An eyepiece waveguide for an augmented reality display system may include an optically transmissive substrate, an input coupling grating (ICG) region, a multi-directional pupil expander (MPE) region, and an exit pupil expander (EPE) region. The ICG region may receive an input beam of light and couple the input beam into the substrate as a guided beam. The MPE region may include a plurality of diffractive features which exhibit periodicity along at least a first axis of periodicity and a second axis of periodicity. The MPE region may be positioned to receive the guided beam from the ICG region and to diffract it in a plurality of directions to create a plurality of diffracted beams. The EPE region may overlap the MPE region and may out couple one or more of the diffracted beams from the optically transmissive substrate as output beams.

Abstract: A pupil separation system includes an input surface and a central portion including one or more dichroic mirrors. The pupil separation system also includes a reflective surface disposed laterally with respect to the central portion and an output surface including a central surface operable to transmit light in a first wavelength range and a peripheral surface operable to transmit light in a second wavelength range different from the first wavelength range. The light in the second wavelength range is reflected by the one or more dichroic mirrors before being reflected by the reflective surface.

Abstract: A method for displaying an image using a wearable display system including directing display light from a display towards a user through an eyepiece to project images in the user's field of view, determining a relative location between an ambient light source and the eyepiece, and adjusting an attenuation of ambient light from the ambient light source through the eyepiece depending on the relative location between the ambient light source and the eyepiece.

Abstract: An augmented reality display system. The system can include a first eyepiece waveguide with a first input coupling grating (ICG) region. The first ICG region can receive a set of input beams of light corresponding to an input image having a corresponding field of view (FOV), and can in-couple a first subset of the input beams. The first subset of input beams can correspond to a first sub-portion of the FOV. The system can also include a second eyepiece waveguide with a second ICG region. The second ICG region can receive and in-couple at least a second subset of the input beams. The second subset of the input beams can correspond to a second sub-portion of the FOV. The first and second sub-portions of the FOV can be at least partially different but together include the complete FOV of the input image.

Abstract: Diffraction gratings provide optical elements in head-mounted display systems to, e.g., incouple light into or out-couple light out of a waveguide. These diffraction gratings may be configured to have reduced polarization sensitivity. Such gratings may, for example, incouple or outcouple light of different polarizations with similar level of efficiency. The diffraction gratings and waveguides may include a transmissive layer and a metal layer. The diffraction grating may comprises a blazed grating.
