Title: Ryoji Kondo: Innovator in Optical Systems

Introduction

Ryoji Kondo stands out as a prominent inventor based in Yokohama, Japan, specializing in advancements in optical systems and image display technologies. With a portfolio of eight patents, Kondo has significantly contributed to the fields of visual display and optical engineering.

Latest Patents

One of Kondo's notable recent patents is for an optical system and image display apparatus. This innovative optical system enables the introduction of light from a display element to an observer in a refined manner. It features a structured arrangement including a first phase plate, a semi-transmissive reflective surface, a lens, a second phase plate, and a polarization beam splitter. The unique construction reflects a first linearly polarized light while allowing a second orthogonal linearly polarized light to pass through. Notably, the semi-transmissive reflective surface has a higher reflectance than transmittance, optimizing the visual output.

Furthermore, his image display apparatus includes an eyepiece optical system designed to guide light from an image display element to an exit pupil. The eyepiece integrates at least one correction element with varying characteristics between central and peripheral areas. This design minimizes color drift between light emitted from different sections of the display element, enhancing the overall viewing experience.
