Introduction

Tadashi Kitahara is a notable inventor based in Hamamatsu, Japan. He has made significant contributions to the field of photonics, particularly through his innovative patents. With a total of 2 patents, Kitahara continues to push the boundaries of technology.

Latest Patents

One of his latest inventions is a light detecting sensor. This device features a substrate with a cathode and an anode stored in a space demarcated by a casing, which is evacuated. The cathode and the anode are provided on the same surface of the substrate, which has electric insulation, and they have a comb-tooth shape that allows them to mutually engage. This design increases the area where the cathode and anode approach each other, enabling photoelectrons discharged from the cathode through ultraviolet rays to be transmitted in the vacuum and favorably collected in the anode.

Another significant patent is the ultrasonic laser modulator. This device comprises a laser oscillation tube with opposing ends that generates a beam of planar polarized light with multiple wavelengths. It includes an output mirror at one end for reflecting the light beam and a modulation device at the other end for simultaneously modulating various wavelengths of the light beams. The modulation device features an acousto-optical prism that separates the beam into multiple wavelength components, a total reflection mirror for reflecting selected components, and an ultrasonic transducer for generating standing waves perpendicular to the selected components for modulation.
