Title: Takuji Satoh: Innovator in Optical Systems
Introduction
Takuji Satoh is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical systems, holding a total of 5 patents. His work focuses on advancing technologies that enhance projection and imaging systems.
Latest Patents
One of Satoh's latest patents is a 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 also addressing aberrations in the arc-shaped region around the optical axis.
Another notable patent is a 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 that moves light-receiving members relative to the illuminating section and optical system.
