摘要： A visual display device is provided for delivering a generated image, preferably combinable with environment light, to the eye of a user. Light from an image generator such as a CRT, LED or LCD is reflected from a fold mirror away from a user's eye towards a combiner. The image is reflected from the combiner and magnified, optionally combined with light from the environment and passes back through the fold mirror towards the eye of the user. In one embodiment, an optical element such as a meniscus lens or PCX lens is used to present the user with a substantially flat focal field and/or a Fresnel lens or diffractive optical element is used to aim rays from the image to the field curvature corrective lens in order to maintain maximum contrast.

摘要： A visual display device is provided for delivering a generated image, preferably combinable with environment light, to the eye of a user. The device is lightweight and compact but yields a high quality image. In one embodiment, a shroud protects from stray light and holds optical elements in desired alignment. In one embodiment an image generator is masked by at least two masks to provide for a high quality image without waste. In one embodiment, a removably mounted shield or activatable device and convert the apparatus from a see-through device to an immersion device and back again. In one embodiment, the device can be comfortably mounted to the user's head while still allowing for use of conventional eyeglasses. A tracker for outputting an indication of the orientation, attitude and/or position of a head-mounted display (HMD) may be provided. The tracker can be configured so that it is incorporated in the HMD housing and/or can be easily decoupled from the HMD, so that the HMD can be used without the tracker (e.g. for watching movies). Preferably, decoupling involves unplugging a single electrical connector (such as a cable) and unfastening a mechanical connection (such as a strap). Preferably the tracker provides pass-through of signal to the HMD and, when the tracker is coupled to the HMD, only a single cable or other data link connects the HMD-tracker combination to the host computer. In one embodiment, the tracker uses magnetic sensors. In another embodiment, one or more inertial sensors, such as a rate gyro and/or accelerometers are used.

摘要： A system which can automatically display either regular two dimensional images or three dimensional images: The system includes, a processor which executes a program, a display, eye glasses which have electronically controllable lenses, and a detector unit connected between the processing unit and the display. Prior to displaying a three dimensional image, the processor sends a signal to the display which represents a particular bar code. The bar code indicates if the following three dimensional images will be displayed in page flip mode or in an interlaced mode. The detector unit detects the bar code and activates the special glasses so that the lenses in the glasses are alternatively opened and closed as frames are displayed. At the end of the three dimensional presentation, the processor sends another bar code to the display. The detector detects this bar code and the systems resumes normal two dimensional operation with both lenses in the glasses being open at all times. The present system can display a three dimensional "widow" on a screen which has normal two dimensional data. The three dimensional window is surrounded by a border which is detected by the detector unit and only the data within this border or window is displayed in three dimensional page flip or interlaced mode.

摘要： The intensified visual display relates to visual displays which combine generated images with the view of the environment surrounding a user and transmit such combined visual information to the eye position of the user. A fold mirror (1) frequently utilized in such displays reflects only a fraction of the light striking it and, similarly, transmits only a different fraction of the light reaching it. The fold mirror (1) will reflect a maximum amount of light when such light is S polarized and transmit a maximum amount of light when the light is P polarized. If the image generator produces S polarized light, one quarter-wave plate (3) is used to assure that image light to be reflected by the fold mirror (1) is S polarized while image light to be transmitted through the fold mirror (1) is P polarized. If the image generator produces P polarized light, a first quarter-wave plate (31) and a second quarter-wave plate (32) are employed.

摘要： A depixelator for improving the image generated by a pixelated image generator, using a non-periodic optic element, is provided. By providing a non-periodic optic element, artifacts such as moire patterns generated by periodic devices such as crossed-gratings, can be reduced or eliminated. The optic device preferably includes a plurality of randomly spaced and/or sized dimples or specks for diffracting a substantial portion of light from pixels into interpixel regions, with the depth of the specks preferably smoothly varying across the surface.

摘要： The depixelated visual display relates to visual displays which combine generated images with the view of the environment surrounding a user and transmit such combined visual information to the eye position of the user. Image generators, such as a cathode ray tube and a liquid crystal display, produce an image composed of a multiplicity of pixels in a plane. The dark area between pixels becomes more prominent in a visual display. To eliminate this dark area while conserving photons, the depixelated visual display has a crossed diffraction grating (1) placed parallel to the pixel plane of the image generator on the side from which light exits the pixels. Prior techniques for depixelation had not controlled the direction into which image light is diffracted, as does the crossed diffraction grating (1), and, unlike the crossed diffraction grating (1), required sources of light which create heat that can be detrimental to a liquid crystal display.
