Title: Innovations by Makoto Yoshimura

Introduction

Makoto Yoshimura is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of optical systems and projection technology. With a total of 2 patents, his work has advanced the capabilities of projection display devices.

Latest Patents

Yoshimura's latest patents include a projection display device and an optical system that modulates separated P-polarized light and S-polarized light. This innovative optical system achieves nearly double the resolving power with a single projector while eliminating the need for a convergence device. The system utilizes a 1:1 relay lens in place of a traditional projector lens in an RGB split-combine projection system. It also incorporates a quarter-wave plate for P-S polarization separation. In operation, the RGB composite light is divided into P-polarized and S-polarized light using a PS separation wire grid. The S-polarized light is modulated by a luminance signal at a Y device, while the P-polarized light is similarly modulated. The modulated lights are then combined at a PS composite wire grid to project synthetic light onto a screen.
