Title: Noriyuki Aizawa: Innovator in Optical Inspection Technology

Introduction

Noriyuki Aizawa is a prominent 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 enhancing the performance and longevity of optical components.

Latest Patents

Aizawa's latest patents include an optical defect inspection apparatus. This invention utilizes 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 surfaces of these mirrors deteriorate due to illumination by the laser beam, leading to reduced reflectance. To prevent the light quantity of the laser beam entering the beam expander from falling below a reference value, Aizawa's design incorporates a mechanism that changes the position of the illuminated areas on the mirrors. This is achieved through a structure that rotates and/or translates the reflecting surfaces while maintaining the same optical axis. As a result, the useful life of each plane mirror is prolonged without displacing the optical axis.

Career Highlights

Aizawa is currently employed at Hitachi High-Technologies Corporation, where he continues to develop cutting-edge technologies in optical inspection. His work has been instrumental in advancing the capabilities of optical systems used in various applications.
