Title: Shingo Tanaka: Innovator in Optical Inspection Technology

Introduction

Shingo Tanaka is a notable inventor based in Hitachinaka, Japan. He has made significant contributions to the field of optical inspection technology, holding two patents that showcase his innovative approach to improving optical defect inspection apparatuses.

Latest Patents

Tanaka's latest patents focus on an optical defect inspection apparatus that utilizes a laser beam. The apparatus features a laser beam oscillated from a laser source, which is folded in its path by first and second plane mirrors before entering a beam expander. The surface of each plane mirror deteriorates due to illumination by the laser beam, leading to reduced reflectance. To maintain the light quantity of the laser beam entering the beam expander above a reference value, the position on each of the plane mirrors is adjusted. This adjustment is achieved through a structure that rotates and/or translates the reflecting surface of each plane mirror while keeping the optical axis unchanged. This innovative design prolongs the useful life of each plane mirror without displacing the optical axis.
