Title: Nobukazu Banjo: Innovator in Electro-Optic Technology
Introduction
Nobukazu Banjo is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electro-optic technology, holding a total of 6 patents. His work focuses on developing advanced probes and oscilloscopes that enhance measurement capabilities in various applications.
Latest Patents
Among his latest innovations are the electro-optic probe and the magneto-optic probe. The electro-optic probe features a laser diode that emits a laser beam based on a control signal from a measuring instrument. It includes an electro-optic or magneto-optic element with a reflection film, a separator that allows the laser beam to pass while reflecting the beam from the reflection film, and two photodiodes that transform the reflected beam. Additionally, a protective member made of weak dielectric material, such as a glass plate, may cover the electro-optic or magneto-optic element.
Another notable invention is the electro-optic sampling oscilloscope (EOS oscilloscope). This device utilizes an electro-optic probe containing an electro-optic crystal, which is influenced by an electric field from a measured signal. Laser pulses are directed to the electro-optic crystal, where they undergo polarization. The oscilloscope then produces measurement data that represent the waveform of the measured signal, allowing users to select specific data for display.
