Latest Patents

Di Hu holds a patent for "Optical systems with artifact blocking structures." This invention involves an electronic device that includes a display with a waveguide and a surface relief grating (SRG) on the waveguide. The SRG is designed to direct image light towards an eye box, while an optical blocker partially overlaps the SRG. The blocker consists of a first optical wedge with a curved surface and a second optical wedge, which is separated from the curved surface by an air gap or a low refractive index material. The unique design of the curved surface allows the first optical wedge to propagate world light incident upon the blocker within a selected range of incident angles away from the SRG through total internal reflection. This innovation effectively blocks high incident angle world light from reaching the SRG, thereby preventing unsightly rainbow artifacts at the eye box.
