Title: The Innovative Contributions of Yutaro Hamatani

Introduction

Yutaro Hamatani is an accomplished inventor based in Tokyo, Japan, known for his groundbreaking work in the field of optical fiber technology. With a total of two patents to his name, Hamatani has made significant contributions that enhance the functionality and sensitivity of optical devices used in various applications.

Latest Patents

One of Hamatani's most notable inventions is an advanced optical fiber sensor designed to measure the refractive index of media with high sensitivity across a wide range. This sensor integrates an optical fiber that experiences transmission loss due to leakage in the clad propagation mode from a portion of its core and clad, featuring a Bragg grating. It includes a specialized light source that allows light in the clad propagation mode to enter the optical fiber, along with a light-receiving section that captures the transmitted or reflected light. This setup enables accurate measurements of the refractive index based on the total intensity of the received light.

Another significant patent from Hamatani is the on-vehicle fuel property detection device. This innovative device employs an optical fiber structured with a core, clad, and fiber jacket. By removing the fiber jacket at the portion where a grating is applied, the clad comes into contact with the fuel fed to the vehicle's injector. The detection device also encompasses a light source that sends light in the clad mode wavelength and a light-sensitive component that detects the intensity of light transmitted through the grating section. This device can be installed in a fuel tank or between the fuel pump and injector, enhancing the efficiency of fuel property detection.
