Keiichiro Itoh

Title: Keiichiro Itoh and Holographic Storage Innovation.

Introduction

Keiichiro Itoh is an inventor based in Iruma, Japan, associated with Nippon Telegraph and Telephone Corporation. His patent work includes an invention for optical waveguides and holographic data storage.

Latest Patents

Itoh is credited with 1 patent: “Optical Waveguide, Holographic Medium, Holographic Storage and Retrieval Method and System.” The invention describes a holographic medium that combines an optical waveguide, a diffraction grating layer, and a storage layer. During recording, reference and object beams enter the waveguide. During retrieval, the reference beam travels through the core layer and is diffracted by the grating, allowing the stored object beam to be recovered from the storage layer.

Career Highlights

Itoh’s listed patent reflects work on optical technologies for storing and retrieving information through holography. The disclosed design uses the waveguide and diffraction grating to direct light between the optical structure and the storage layer.

Collaborations

Itoh’s listed coworkers include Hiroshi Yoshikawa and Takaya Tanabe. His patent is associated with Nippon Telegraph and Telephone Corporation.

Conclusion

Keiichiro Itoh’s patent describes a holographic storage and retrieval system that uses an optical waveguide and diffraction grating to manage light and recover stored information.
