申请(专利权)人: KOREA UNIVERSITY RESEARCH AND BUSINESS FOUNDATION, SEJONG CAMPUS 发明人: H Kim 摘要: Various embodiments relate to an FTIR-based diffractive optical structure, and a waveguide device and an augmented reality display each including same. The augmented reality display may comprise: a...
produced by a display engine, to a location where a user of a device can view the image as a virtual image in an augmented reality environment. As this is still an emerging technology, there are certain challenges associated with utilizing waveguides to display images of virtual objects to a ...
light from the outside world corresponding to similar wavelength bands can also be prevented from reaching the viewer's eyes. This may cause problems in augmented reality systems in which it may be desirable for the user to be able to see the world as clearly as possible. To address this,...
We propose a polarization multiplexing structure based on multilayer reflective polarized volume holographic gratings(PVGs) to improve the field of view and brightness of the augmented reality waveguide display. The multilayer structure forms the splicing of different response bandwidths by stacking PVGs ...
virtual reality, augmented reality, gaming etc. Optical gyroscopes typically have the highest performance and are based on interferometric measurements and the Sagnac effect (a phenomenon encountered in interferometry that is elicited by rotation). Since optical gyroscopes do not have any moving parts, ...
Waveguide displays, a highly competitive solution for augmented reality (AR), have attracted a lot of interest. A polarization-dependent binocular waveguide display using polarization volume lenses (PVLs) and polarization volume gratings (PVGs) as input and output couplers, respectively, is proposed....
Augmented reality optical systems include a waveguide structure that includes a waveguide layer supported by a substrate. The input diffraction grating and the output diffraction grating are present in the waveguide layer and are laterally separated from each other. The input light from the display is...
An augmented reality optical system comprises a waveguide structure that includes a waveguide layer supported by a substrate. An input grating and an output grating reside within the waveguide layer and are laterally spaced apart. Input light from a display is made incident upon the input grating....
