Title: Innovations of Fei Cheng in Optical Devices
Introduction
Fei Cheng is an accomplished inventor based in Granger, IN (US). He has made significant contributions to the field of optical devices, holding a total of 3 patents. His work focuses on enhancing visual technologies, particularly in augmented reality and reflective optical devices.
Latest Patents
One of his latest patents is a see-through reflective metasurface. This innovative optical device features a reflective metasurface designed for a targeted optical wavelength. The metasurface consists of a sub-wavelength periodic arrangement of meta-atoms formed by patterned isolated gap surface plasmon (GSP) resonators. These resonators include a patterned optically thin metal layer, an optically thick metal layer, and an insulator layer, allowing for a designed percentage of light transparency. This technology can be utilized as a combiner element surface in near-eye display assemblies.
Another notable patent is for an augmented reality display. This near-eye display assembly includes a frame, a combiner, a secondary mirror, an image source, and an optical fold element. The design allows for the formation of an intermediate image in the optical path, ensuring that images are directed to the user's eyebox. The combiner and secondary mirror are configured in an off-axis folded geometry, which corrects optical aberrations and provides a field of view of at least 30 degrees.
