Title: The Innovative Contributions of Chiko Otani
Introduction
Chiko Otani is a prominent inventor based in Wako, Japan, known for his significant contributions to optical technology. With a total of five patents to his name, Otani has made remarkable advancements in the field of optical interference measurement and terahertz wave generation.
Latest Patents
One of his latest patents is an optical interference measuring apparatus and method. This invention includes a measuring unit that acquires an interferogram of an interference wave by irradiating a measuring target and a reference surface with electromagnetic waves. The reflected waves from both surfaces interfere, allowing for the configuration of an intensity profile in the depth direction through Fourier transform. The signal processing unit estimates parameters for a model formula based on the assumed structure of the measurement target, selecting an optimal model using statistical techniques.
Another notable patent is the terahertz wave generating method and apparatus. In this invention, first and second laser beams are incident on a difference frequency mixing unit, generating a terahertz wave whose frequency is determined by the frequency difference between the two laser beams. By spatially shifting the laser beams in the frequency gradient direction, the frequency difference in the overlapping region is altered, allowing for the generation of a terahertz wave of a single frequency.
