An optical combiner (101, 301, 400) in augmented reality and a related device. The optical combiner (101, 301, 400) comprises a transparent substrate (202, 402) and a supersurface layer (201, 401) provided on the surface of the transparent substrate (202, 402). The supersurface layer (201, 401) comprises a plurality of supersurface units (403) arranged in two dimensions. The interval between two adjacent supersurface units (403) of the plurality of supersurface units (403) gradually changes along one or two dimensions, and the relative angle between any two adjacent supersurface units (403) is not zero. The optical combiner (101, 301, 400) can improve the transmittance of the ambient light, and improve the uniformity and the field of view of an image. |
