Latest Patents

Sunohara's latest patents include a hologram recording material and a hologram recording medium. The hologram recording material is designed to eliminate the need for pre-exposure treatment during recording. It achieves high refractive index change, high sensitivity, low scattering, environmental resistance, durability, low dimensional change, and high multiplicity, making it suitable for volume hologram recording. The hologram recording medium comprises a matrix material with a softening temperature of 50°C or higher and a photopolymerizable monomer that remains in a liquid phase at room temperature.

Additionally, he has developed an optical recording medium that features a recording layer and a reflecting film on an optically transparent substrate. The recording layer's principal component is a dye, and it incorporates virtual recording cells within grooves. Recording marks of varying sizes are formed by modulating the irradiation time of a laser beam, allowing for multiple levels of reflectance during regeneration.
