Abstract: An optical assembly a substrate having a first surface and a second surface that is opposite to and substantially parallel with the first surface. The first surface has a first curved profile and the second surface has a second curved profile. The optical assembly also includes a beam splitter on the first surface and a reflector on the second surface. The optical assembly is configured to transmit image light received at the first surface in an optical path that includes reflection at each of the reflector and the beam splitter before the image light is output from the second surface. The optical assembly is also configured to transmit ambient light received at the first surface such that the second light is output from the second surface without undergoing reflection at either the reflector or the beam splitter. A method of transmitting light through the optical assembly is also disclosed.

Abstract: A display device includes a projector and a display that has a first surface and a second surface. The projector is configured to project image light toward the display. The display is configured to output diffused image light from the first surface and to transmit ambient light from the second surface to the first surface. The display device also includes an optical assembly that has a substrate with substantially uniform thickness. The optical assembly is configured to receive the diffused image light and transmit a portion of the diffused image light output from the first surface of the display at a first optical power. The optical assembly is also configured to receive the ambient light and transmit a portion of the ambient light through the optical assembly at a second optical power that is less than the first optical power.

Abstract: A system includes a light outputting device configured to output a divergent light. The system also includes a lens configured to convert the divergent light incident thereon from a first side of the lens to a collimated light substantially covering a light receiving region located at a second side of the lens, the lens including a plurality of Fresnel structures formed on at least one of a first lens surface or a second lens surface of the lens. Each Fresnel structure includes a slope facet and a draft facet. At least one of the draft facets is a first type of draft facet configured to not interact with a ray of the divergent light that is non-parallel with the at least one of the draft facets.

Abstract: A scanning projector of a near-eye display device may be coupled to a waveguide and include a multi-ridge light source to provide a light beam. A distance between ridges of the light source may be larger than one pixel and the ridges may be aligned horizontally, vertically, or at an angle. A two-dimensional (2D) beam scanner optically coupled to the light source may generate a light field by performing a biresonant scan of the light beam. The projector may also include or be coupled to a controller to cause the beam scanner to scan the light beam about a first axis and a second axis within a field of view following a coherent Lissajous pattern while varying a brightness of the light beam to provide the image.

Abstract: A display device includes a display module for providing first image light. The display device also includes a first optical element for receiving and transmitting the first image light from the display module. The display module includes a region from which the first image light is provided in directions other than a direction perpendicular to the first optical element. The display device further includes a second optical element so that the second optical element receives the first image light transmitted through the first optical element and sends the received first image light back toward the first optical element as second image light. The first optical element receives the second image light from the second optical element and sends the second image light back toward the second optical element, and the second optical element receives and transmits the second image light from the first optical element.

Abstract: A system for making a holographic medium for use in generating light patterns for eye tracking includes a light source configured to provide light and a beam splitter configured to separate the light into a first portion of the light and a second portion of the light that is spatially separated from the first portion of the light. The system also includes a first set of optical elements configured to transmit the first portion of the light for providing a first wide-field beam onto an optically recordable medium and one or more diffractive optical elements configured to receive the second portion of the light and project a plurality of separate light patterns onto the optically recordable medium for forming the holographic medium.

Abstract: A head-mounted display (HMD) for improved field of view (FOV) is provided. The head-mounted display (HMD) may include a display element to provide display light. The head-mounted display (HMD) may also include a lens element to provide display light to a user of the head-mounted display (HMD). The head-mounted display (HMD) may further include an optical element comprising at least one waveguide to provide improved central or peripheral field of view (FOV) for the user of head-mounted display (HMD). In some examples, the waveguide may be part of central optics and/or peripheral optics. The waveguide may have a planar waveguide profile or a curved waveguide profile. In some examples, the waveguide may be stacked or may include a graded index (GRIN) layer.
