Title: Atsushi Sube: Optical Measurement Innovations

Introduction

Atsushi Sube is an inventor based in Osaka, Japan, whose patent work focuses on optical displacement measurement. His inventions address accurate workpiece profiling and image generation through systems that scan slit light.

Latest Patents

Sube’s listed patent portfolio includes 2 patents, both concerning optical displacement meters.

The first invention describes an optical displacement meter designed to capture profiles at multiple positions on a workpiece without requiring a conveyor or linear-motion mechanism. It integrates the light-projecting, light-collecting, and image-capturing components in a Scheimpflug arrangement. A motor rotates the module inside a housing while maintaining that arrangement, scanning slit light across the workpiece. The design aims to support accurate measurement while addressing operational dust protection and safety.

The second invention concerns an optical displacement meter that swings its light-projecting and receiving system to scan slit light. It acquires the system’s rotation angle and combines that information with image-sensor measurements to calculate three-dimensional coordinates. The meter can use those coordinates to output a height image of the workpiece on an XY plane, as well as a received-light image.
