Title: Innovations by Yoshinobu Tsujimoto
Introduction
Yoshinobu Tsujimoto is a notable inventor based in Kashihara, Japan. He has made significant contributions to the field of optical technology, holding a total of 4 patents. His work focuses on developing advanced sensors and optical devices that enhance performance and efficiency.
Latest Patents
One of his latest inventions is a fiber optic magnetic field sensor that employs the Faraday effect. This innovative sensor features two pieces of birefringent substance positioned between the ends of optical fibers and a rod lens for polarization separation. The design incorporates a reflex optical system that allows light to reciprocate through a Faraday material, resulting in a magnetic field sensor that is compact, lightweight, cost-effective, and highly accurate.
Another significant patent is an optical switching device. This device connects the end faces of multiple optical waveguides to one end face of a focusing rod lens. A reflection means with a tilted reflection plane is positioned behind the other end face of the lens. By varying the angle of the reflection plane, the device achieves selective switching of the waveguides or modulates the amount of rays transmitted through them. The use of a semitransparent filter allows for separate control of attenuation for different wavelengths.
