Optical combiner and related device for augmented reality |
| abstract |
This application provides an optical combiner and a related device for augmented reality. The optical combiner includes a transparent substrate and a metasurface layer. The metasurface layer is disposed on a surface of the transparent substrate. The metasurface layer includes a plurality of metasurface units arranged two-dimensionally. A spacing between two adjacent metasurface units in the plurality of metasurface units gradually changes along one or two dimensions, and a relative angle between any two adjacent metasurface units is not zero. The optical combiner can increase an ambient light transmittance and increase uniformity and a field of view of an image. |
