摘要： An optical device includes a first set of one or more electrodes, a second set of one or more electrodes distinct and separate from the first set of one or more electrodes, and a solution containing transparent metal ions in a liquid or gel electrolyte. The solution is located between the first set of one or more electrodes and the second set of one or more electrodes. The optical device may operate as an optical dimming device, which may be used in head-mounted display devices or as dimmable windows or shutters.

摘要： A device is provided. The device includes a first lens configured to provide a first optical power that is variable within a first optical power adjustment range at a first step resolution. The device also includes a second lens coupled with the first lens and including a deformable member that is deformable to vary an optical power of the second lens. The second lens is configured to provide a second optical power that is variable within a second optical power adjustment range at a second step resolution, the second step resolution being smaller than the first step resolution.

摘要： A device includes a display including multiple pixels, each pixel having an optical emitter to provide at least one light beam from an image. The device also includes an optical element to relay light beams from the display to a viewer through an eyebox, the eyebox limiting an area that includes a pupil of the viewer and a varifocal assembly to direct, through the eyebox, light beams having a first and second mutually orthogonal polarization states, according to a desired mode of operation of the device, and associated with a first and second field of view of the image in a focused mode of operation of the device, and an immersive mode of operation of the device, respectively. A memory storing instructions and a processor to execute the instructions to cause the device to perform a method for adjusting between the immersive mode and the focused mode are also provided.

摘要： An optical assembly is configured to receive visible scene light at the backside of the optical assembly and to direct the visible scene light on an optical path toward the eyeward side. The optical assembly includes a dimming element disposed on the optical path, where the dimming element includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. A display layer is disposed on the optical path between the eyeward side of the optical assembly and the dimming element. The display layer is configured to direct visible display light toward the eyeward side and also to direct activation light to the dimming element, where the activation light is within the range of light wavelengths to activate a darkening of the photochromic material to dim the visible scene light.

摘要： An optical assembly is configured to receive visible scene light at the backside of the optical assembly and to direct the visible scene light on an optical path toward the eyeward side. The optical assembly includes a dimming element disposed on the optical path, wherein the dimming element includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. An illuminator, coupled to an edge of the dimming element, is configured to selectively emit an activation light within the range of light wavelengths to activate a darkening of the photochromic material to dim the visible scene light.

摘要： An optical assembly includes a beam steering device and a holographic optical element. The beam steering device is switchable between different states including a first state and a second state. The beam steering device includes a first polarization-selective optical element and a first tunable optical retarder optically coupled with the first polarization-selective optical element. The holographic optical element is positioned relative to the beam steering device for receiving light from the beam steering device and projecting a first light pattern while the beam steering device is in the first state and a second light pattern distinct from the first light pattern while the beam steering device is in the second state.

摘要： A headset for augmented reality applications is provided. The headset includes at least one eyepiece configured to provide a see-through image to a user via a transparent optical component, and to provide an artificial image through a display, and a dimming shutter configured to adjust a transparency level of the transparent optical component. The dimming shutter further includes an active liquid crystal layer configured to adjust a transparency level according to an electrical power provided between two electrodes, and a photoactive layer configured to adjust the transparency level upon absorption of an ultraviolet radiation for a selected period of time. A default orientation of a host material in the active liquid crystal layer may be in a dark state or in a clear state, when no electrical power is provided. A method and a memory storing instructions to execute the method for use of the above device are also provided.

摘要： An optical device includes a light source configured to provide a light beam. The optical device includes a light source configured to generate a light beam, and a spatial light modulator (“SLM”) configured to modulate the light beam to provide a hologram for generating a display image. The optical device includes a polarization-selective steering assembly configured to provide a plurality of steering states for the modulated light beam. The optical device includes an image combiner configured to focus the modulated light beam steered by the polarization-selective steering assembly to generate an array of spots at an eye-box of the optical device.
