Latest Patents

Man To Chow holds a patent for an "Optical-digital encoding-decoding system." This system is designed to benefit anti-counterfeiting efforts by utilizing both optical and digital methods for spoof protection, particularly in print anti-spoofing applications. The system 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 decode or decrypt this data, achieving stronger authentication for security-related purposes. The images are encoded into resonant waveguide gratings (RWGs), which allow for angle multiplexing of displayed images and cater to different 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 for better visibility.
