Title: Takeru Utsugi: Innovator in Surface Inspection and Video Display Technologies

Introduction

Takeru Utsugi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the fields of surface inspection and video display technologies. With a total of eight patents to his name, Utsugi's work showcases his innovative spirit and technical expertise.

Latest Patents

Utsugi's latest patents include a surface inspection device and shape measurement software. This defect inspection apparatus features a differential interference contrast illumination system that irradiates a sample surface with two polarized illumination spots. These spots have different phases at a predetermined wavelength and are offset by a predetermined shear amount. The system also includes a differential interference contrast detection system that condenses reflected light beams to generate interference light beams. Additionally, a scanning unit scans the sample surface using the two polarized illumination spots, while a sensor unit converts the interference light beams into interference signals. A height displacement measurement unit processes these signals to measure height displacement, and a height shape reconstruction unit accumulates data to reconstruct the height shape of the sample surface.

Another notable patent is a video display device and video display system designed to minimize color deviation and video distortion. This invention includes a video projection unit, a video deflection unit, and a light guide portion. The video deflection unit deflects video light emitted by the projection unit, allowing it to propagate through the light guide portion, which outputs the video light while reducing color dispersion.
