摘要： A head-mounted display may include a display system and an optical system that are supported by a housing. The optical system may be a catadioptric optical system having a removable lens element and a non-removable lens element. The optical system may include a quarter wave plate that is coated to the non-removable lens element without an intervening adhesive layer. The optical system may further include a reflective polarizer and a linear polarizer. The removable lens element may be selectively attached to the optical system. The removable lens element may be separated from a non-removable lens element by an air gap when the removable lens element is attached to the optical system. The removable lens element may have a convex curved surface that conforms to a concave curved surface of the non-removable lens element.

摘要： The optical system introduces light from a display element displaying an image to an observer. The optical system includes in order from the display element toward the observer, a first phase plate, a semi-transmissive reflective surface, a lens, a second phase plate, and a polarization beam splitter configured to reflect a first linearly polarized light and transmit a second linearly polarized light whose polarization direction is orthogonal to that of the first linearly polarized light. The semi-transmissive reflective surface has a transmittance smaller than a reflectance thereof.

摘要： A display system includes projection optics configured to project a beam of light in a first direction and an eyepiece unit including a first waveguide layer disposed in a first lateral plane and including an incident light surface and an opposing surface opposite the incident light surface and an incoupling diffractive optical element disposed on the incident light surface. The incoupling diffractive optical element is configured to incouple a first portion of the beam of light and to propagate the first portion of the beam of light by total internal reflection in a second direction and transmit a second portion of the beam of light along the first direction. The eyepiece also includes a retroreflector disposed adjacent the opposing surface. The retroreflector is configured to retroreflect the second portion of the beam of light along a reflected direction opposite to the first direction.

摘要： Provided is a light source device and an image display device for providing a high-resolution image while enlarging an eye-box, and contributing to downsizing of the device. The present technology provides a light source device including at least a projection optical system configured to branch light emitted from a light source unit into light in a plurality of directions and emit the light, in which the projection optical system emits the light in the plurality of directions toward an eyepiece optical unit configured to receive light emitted from the projection optical system and emit the light to a retina of a user. Light in at least two directions among the light in the plurality of directions emitted from the projection optical system may be emitted to the same retina.

摘要： An optical system with adjustable eye relief includes a relay lens assembly. The relay lens assembly is defined by a collimating lens and a focusing lens. The optical system includes an aperture stop. The aperture stop is configured to shift axially along an optical axis between the collimating lens and the focusing lens. The optical system also includes an afocal lens assembly. The afocal lens assembly is defined by the focusing lens and an eyepiece. Additionally, an axial shift of the aperture stop along the optical axis between the collimating lens and the focusing lens changes an eye relief of the eyepiece based on a transverse magnification of the afocal lens assembly.

摘要： 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.

摘要： A display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity may be selected using an array of shutters that selectively regulate the entry of image light into an eye. Each opened shutter in the array provides a different intra-pupil image, and the locations of the open shutters provide the desired amount of parallax disparity between the images. In some other embodiments, the images may be formed by an emissive micro-display. Each pixel formed by the micro-display may be formed by one of a group of light emitters, which are at different locations such that the emitted light takes different paths to the eye, the different paths providing different amounts of parallax disparity.
