Latest Patents

Peisong Hua holds a patent for an "Optical-digital encoding-decoding system." This system is designed to improve anti-counterfeiting measures by utilizing both optical and digital methods for spoof protection. The technology employs an encoded medium, such as a security label, to display images that are encoded with digital data. A decoding device is then used to decrypt this data, providing stronger authentication for security-related purposes. The images are encoded into resonant waveguide gratings (RWGs), which allow for angle multiplexing of displayed images, addressing various secrecy requirements. Additionally, aperiodic diffraction gratings are utilized in RWGs to enhance the viewing experience of selected images, broadening the beamwidths of outgoing light beams.
