A virtual or augmented reality headset is provided having a frame, a pair of virtual or augmented reality eyepieces, and an interpupillary distance adjustment mechanism. The frame includes opposing arm members, a bridge positioned intermediate the opposing arm members, and one or more linear rails. The adjustment mechanism is coupled to the virtual or augmented reality eyepieces and operable to simultaneously move the eyepieces in adjustment directions aligned with the plurality of linear rails to adjust the interpupillary distance of the eyepieces.

A color translating UV microscope for research and clinical applications involving imaging of living or dynamic samples in real time and providing several novel techniques for image creation, optical sectioning, dynamic motion tracking and contrast enhancement comprises a light source emitting UV light, and visible and IR light if desired. This light is directed to the condenser via a means of selecting monochromatic, bandpass, shortpass, longpass or notch limited light. The condenser can be a brightfield, darkfield, phase contrast or DIC. The slide is mounted in a stage capable of high speed movements in the X, Y and Z dimensions. The microscope uses broadband, narrowband or monochromat optimized objectives to direct the image of the sample to an image intensifier or UV sensitive video system. When an image intensifier is used it is either followed by a video camera, or in the simple version, by a synchronized set of filters which translate the image to a color image and deliver it to an eyepiece for viewing by the microscopist. Between the objective and the image intensifier there can be a selection of static or dynamic switchable filters. The video camera, if used, produces an image which is digitized by an image capture board in a computer. The image is then reassembled by an overlay process called color translation and the computer uses a combination of feedback from the information in the image and operator control to perform various tasks such as optical sectioning and three dimensional reconstruction, coordination of the monochromater while collecting multiple images sets called image planes, tracking dynamic sample elements in three space, control of the environment of the slide including electric, magnetic, acoustic, temperature, pressure and light levels, color filters and optics, control for microscope mode switching between transmitted, reflected, fluorescent, Raman, scanning, confocal, area limited, autofluorescent, acousto-optical and other modes.

An eyepiece for a head mounted display includes a display module, end reflector, and viewing region. The end reflector is disposed at an opposite end of the eyepiece from the display module to reflect the display light back from a forward propagation path to a reverse propagation path. The viewing region is disposed between the display module and the end reflector and includes a partially reflective surface, that passes the display light traveling along the forward propagation path and redirects the display light traveling along the reverse propagation path out of an eye-ward side of the eyepiece along an emission path. The partially reflective surface has a compound folding angle such that the emission path of the display light emitted from the eyepiece is folded along two axes relative to the reverse propagation path between the end reflector and the partially reflective surface.

A goggle system for providing a personal media viewing experience to a user is provided. The goggle system may include an outer cover, a mid-frame, optical components for generating the media display, and a lens on which the generated media displayed is provided to the user. The goggle system, or head mounted display may have any suitable appearance. For example, the goggle system may resemble ski or motorcycle goggles. To enhance the user's comfort, the goggle system may include breathable components, including for example breathable foam that rests against the user's face, and may allow the user to move the display generation components for alignment with the user's eyes. In some embodiments, the goggle system may include data processing circuitry operative to adjust left and right images generated by the optical components to display 3-D media, or account for a user's eyesight limitations.

An observation optical system includes an image display element, a relay optical system having a plurality of lenses 4 and a first reflection-type volume hologram element (HOE), and an eyepiece optical system having a second reflection-type HOE. The observation optical system is arranged along the face to the side head of the observer. The first reflection-type HOE has a power and is configured to compensate for chromatic aberrations. The plurality of lenses is configured to compensate for decentered aberrations and chromatic aberrations. The second reflection-type HOE is a configured to exert power on bundles of rays and to compensate for chromatic aberrations. A light-transmitting plate is sandwiched between the first reflection-type HOE and the second refection-type HOE.
