    摘要： An image display device, including a light-emitting pixel array operable to emit a plurality of two-dimensional images each comprising a plurality of pixels; a light field converter comprising a coherent optical fiber plate including a plurality of optical fibers, wherein the optical fiber plate has a first surface and a second surface, and an array of lenslets arranged along the second surface, wherein the array of lenslets is configured to have a focal surface conforming to the second surface of the optical fiber plate; wherein the light field converter is operable to transform pixels from each of the plurality of two-dimensional images into corresponding diverging rays; wherein the diverging rays form virtual three-dimensional image in an image-forming region.

    摘要： An HMD includes a mounting band for surrounding a head H of a user. The mounting band includes a case, a stretching unit, an adjustment mechanism that adjusts a length of the stretching unit to be accommodated in the case by relatively moving the stretching portion with respect to the case, a winding target member, and a spring member which is fixed at a front portion thereof to the stretching unit and at a rear portion thereof wound on the winding target member and in which an unwinding amount from the winding target member changes according to the length of the stretching unit accommodated in the case. The spring member generates elastic force that acts in a direction in which the stretching portion is accommodated into the case. A first elastic force of the spring member generated by a first unwinding amount and a second elastic force of the spring member generated by a second unwinding amount are equal to each other.

    摘要： An electronic loupe (400) features a view piece (401) mounted to a headpiece (405) by a linkage (406). A camera (402) and LED light (403) are mounted (404) in front of the view piece (401) to provide an image in the view piece (401) on displays (not shown) for the user. A control box (410) may be wired to the electronic loupe, or wirelessly connected, or the controls for the electronic loupe may reside on the view piece (401) and the headpiece (405). Other controls, such as a remote control or a foot pedal, are also disclosed. Illumination controls and location are designed for ideal illumination along various spectra. Automatic recording and documentation is also provided.

    摘要： Systems and methods for reducing glare from a heads-up display (HUD). Internal and external antireflective coatings may be provided on interior and outer surfaces of glass layers surrounding a holographic polymer layer. A substrate guided hologram may be integrated into a HUD to diffract and direct external radiation to the edge of a HUD. An arrangement for forming a substrate guided hologram includes an array of reflectors and a shaped glass block. Antireflective coated glass layers may be index-matched to opposite sides of a holographic polymer film prior to recording a reflection hologram. An inactive playback beam may be used to monitor the diffraction efficiency of a reflection hologram and of a spurious transmission hologram with the recording of the reflection hologram to maximize the difference between the diffraction efficiencies of useful reflection hologram and spurious transmission hologram.
