摘要： A multi-focal system includes a display pixel array, a pixelated polarization array, and a Pancharatnam-Berry phase (PBP) lens. The display pixel array includes a first display pixels generating first display light and a second display pixels generating second display light. The pixelated polarization array has first pixels and second pixels. The first pixels are aligned with the first display pixels to generate a first polarized light having a first polarization orientation. The second pixels are aligned with the second display pixels to generate a second polarized light having a second polarization orientation different from the first polarization orientation. The PBP lens is configured to focus the first polarized light having the first polarization orientation to a first focal length and focus the second polarized light having the second polarization orientation to a second focal length that is greater than the first focal length.

摘要： A display device includes an optical diffuser configured to, in response to receiving image light, output diffused image light having a same polarization as the image light. The optical diffuser is also configured to transmit ambient light. The display device also includes an optical assembly that includes a substrate, a reflector coupled to the substrate, and a beam splitter coupled to the substrate. The optical assembly is configured to transmit the diffused image light at a first optical power by reflecting the diffused image light at the reflector and at the beam splitter and to transmit the transmitted ambient light at a second optical power that is less than the first optical power without reflection at the reflector or the beam splitter. A method for transmitting light through the display device is also disclosed.

摘要： An optical assembly includes a plurality of successive optical stages that are configured to transmit light at a variable overall optical power by configuring one or more stages of the successive optical stages. A respective optical stage of the successive optical stages includes an active optical element that is configurable to be in a first state at a first time and a second state at a second time that is distinct from the first time. The active optical element, in the first state, has a first respective optical power for light of a first polarization and a second respective optical power, that is different from the first respective optical power, for light of a second polarization that is orthogonal to the first polarization. The active optical element, in the second state, has a third optical power for light of the first polarization and light of the second polarization.

摘要： A beam scanner includes a substrate, a tiltable reflector hingedly supported by the substrate, and a reflective polarizer. The reflective polarizer is supported over the tiltable reflector and configured to receive and redirect a light beam towards the tiltable reflector for scanning the light beam. A projector includes the beam scanner and a light source providing a light beam. The light beam may be modulated in brightness, color, or polarization synchronously with tilting the reflector, thereby forming an image in angular domain after propagating through a pupil-replicating waveguide. At least one folding mirror may be provided for directing the light beam from the light source around the pupil-replicating waveguide, resulting in a compact overall configuration.
