Title: Innovations of Toshiki Okumura
Introduction
Toshiki Okumura is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of optical devices, holding a total of 2 patents. His work focuses on advancing technologies that enhance projection systems.
Latest Patents
One of his latest patents is the "Scanning Projection Optical Device." This device is designed to utilize relatively small optical components while employing a catadioptric system that achieves a high numerical aperture (NA). It features arc-shaped object and image regions positioned outside the optical axis, with a projecting magnification of 1. The system is telecentric in both object and image field sections, incorporating a positive power lens system, a non-power lens system, and a concave mirror. This configuration satisfies the Petzval condition to correct field curvature while addressing aberrations in the arc-shaped region around the optical axis.
Another significant patent is the "Wide-Field Exposure Optical System." This system performs projection by scanning an object with a predetermined scan width. It includes an illuminating section that lights the object in a circular arc region, along with a reflecting and refracting optical system that corrects aberrations. The system is designed to form an image of the illuminated object as a circular arc on the image surface. It also features a driving mechanism for moving light-receiving members relative to the illuminating section and the optical system.
