Title: Motosuke Kiyohara: Innovator in Optical Systems and Photodetectors

Introduction

Motosuke Kiyohara is a notable inventor based in Tokyo, Japan. He has made significant contributions to the fields of optical systems and photodetectors, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

Kiyohara's latest patents include a photodetector and measurement object reader. This photodetector is designed to detect fluorescence emitted from a sample placed on a substrate of a DNA chip. It features an irradiation optical system that guides light through a first optical waveguide, gathers it with a first lens, and irradiates the sample. The reception optical system collects fluorescence at the input-side end surface of a second optical waveguide using a second lens, directing it to a measuring unit. Notably, the irradiation and reception optical systems are separate light guiding paths, with the reception system employing a confocal optical design.

Another significant patent is an optical system and apparatus for magnifying a display panel. This system includes a magnifying lens positioned in front of a display panel, constructed with two convex lenses facing each other. At least one of these surfaces is aspherical, ensuring that the transverse aberration of the lens is less than the diameter of the pupil of the eye at the viewing point. The optical system utilizes a Fresnel lens, with its vortex center located at the edge, allowing for effective magnification of both distant and close instruments.
