Latest Patents

One of Katsumata's latest patents is for a hologram plate and its fabrication process. This invention provides a hologram plate that is utilized with a double-focus replication process. It is integrated with a spacer to impart marring resistance and includes a light-absorbing layer that allows zero-order light and first-order light to maintain substantially the same intensity. The hologram plate comprises an array of collective element holograms designed to diffract parallel light incident at a specific wavelength and angle, converging the light onto a specific focal length position. The structure of the hologram plate consists of a first transparent substrate, a hologram layer, an adhesive layer, and a second transparent substrate. The second transparent substrate defines a surface that comes into contact with a hologram photosensitive material during the replication process.
