Abstract: A display device includes a display, an optical assembly, and a display-moving assembly connected to the display for moving the display between a first position and a second position. When in the first position, the display outputs image light in a first direction substantially parallel to an optical axis of the optical assembly. When in the second position, the display is positioned away from the optical axis of the optical assembly. The display device also includes a partial reflector and a partial reflector-moving assembly connected to the partial reflector for moving the partial reflector between a third position and a fourth position. When the partial reflector is in the third position, the display is in the first position and the display is disposed between the optical assembly and the partial reflector. When the partial reflector is in the fourth position, the display is in the second position.

Abstract: An optical assembly includes at least one substrate that provides a first curved surface and a second surface. The optical assembly also includes a beam splitter on the first curved surface, a reflector on the second surface, and an optical retarder disposed between the beam splitter and the reflector. The optical assembly is configured to receive first light at the first curved surface and reflect the first light at the reflector and subsequently, at the beam splitter before outputting the first light from the reflector. The first light is transmitted through the optical assembly at a first optical power. The optical assembly is also configured to transmit second light at a second optical power that is less than the first optical power. The second light is transmitted through peripheral portions of the beam splitter and reflector without reflection at the reflector.

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: An optical device includes a light source configured to provide illumination light and a waveguide. The waveguide has an input surface, an output surface distinct from and non-parallel to the input surface, and an output coupler. The waveguide is configured to receive, at the input surface, the illumination light provided by the light source and propagate the illumination light via total internal reflection. The waveguide is also configured to redirect, by the output coupler, the illumination light so that the illumination light is output from the output surface for illuminating a spatial light modulator.

Abstract: An optical device includes a first waveguide having a first side and an opposing second side, a spatial light modulator configured to project image light, one or more lenses disposed between the spatial light modulator and the first waveguide, and a first in-coupler coupler coupled with the first waveguide. The spatial light modulator is positioned on the first side of the first waveguide. The first in-coupler is positioned to receive the image light projected by the spatial light modulator and transmitted through the one or more lenses and to redirect at least a first portion of the image light so that the first portion of the image light enters the first waveguide and undergoes total internal reflection inside the first waveguide.

Abstract: Optical binocular disparity detection devices may include an optical combiner and a single image sensor. The optical combiner may include a left input for receiving a left image and a right input for receiving a right image. An output of the optical combiner may be configured to direct the left image and the right image out of the optical combiner. The single image sensor may be configured to receive and sense the left image and the right image from the output and to generate data indicative of a disparity between the left image and the right image. Various other related systems and methods are also disclosed.
