Latest Patents

One of his latest patents is titled "Display apparatus comprising diffractive elements." This invention features an optical engine that forms first input light, which consists of multiple input light beams representing an input image. The modifying unit in this apparatus is designed to create second input light from the first input light. Additionally, the diffractive waveguiding expander device is responsible for producing output light by diffractively expanding the second input light, resulting in multiple output light beams that represent the input image. The modifying unit includes at least one prism to compensate for angular dispersion among the output light beams, which may arise from imperfections in the waveguiding expander device.

Another notable patent is the "Display apparatus for providing an enlarged display area." This invention includes a rotating expander device that generates output light by expanding input light beams. The expander device comprises a waveguide plate and in-coupling and out-coupling elements that facilitate the coupling of guided light into and out of the waveguide plate. The in-coupling element features specific grating vectors that optimize the light coupling process.
