Title: Kenji Narusawa: Innovator in Holographic Technology
Introduction
Kenji Narusawa is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of holographic technology, particularly in the development of systems for issuing and certifying identification cards. With a total of 2 patents, Narusawa's work showcases his innovative approach to enhancing security and data processing.
Latest Patents
Narusawa's latest patents include a system for issuing cards and a system for certifying the card. The first patent involves a computer-generated hologram (CGH) readout section that reproduces an image of the CGH formed in the data storage area of the crude card. This system includes a CGH certifying section that determines the authenticity of the card and retrieves identification information. If the card is verified as genuine, the ID information is processed and personal details, including a face picture of the cardholder, are registered in a database. The final output is a personal ID card, complete with a protective film over the printed surface.
His second patent focuses on a holographic storage medium and the reproduction of data from it. This storage medium features at least one diffraction grating, which is created as a holographic interference fringe pattern. The pattern allows for the two-dimensional or one-dimensional diffraction of an incident light beam. When a light beam is directed at the storage medium, the diffracted light is detected by a photodetector, such as a CCD device, which generates a signal containing the stored data. This signal is then decoded by a processor to reproduce the original data.
