Title: The Innovations of Makoto Okawauchi

Introduction

Makoto Okawauchi is a notable inventor based in Ritto, Japan. He has made significant contributions to the field of optical measurement technology, holding a total of five patents. His work focuses on developing advanced devices and methods for measuring optical characteristics, which are essential in various scientific and industrial applications.

Latest Patents

One of Okawauchi's latest patents is an optical characteristic measurement device and method suitable for spectrum measurement. This innovative device includes a photodetector and a processor. The photodetector features a detection surface larger than the light incident surface that receives light from a spectrometer. The processor is designed to obtain a measurement spectrum detected in a first detection area and a signal intensity detected in a second detection area. It corrects a pre-prepared pattern that exhibits the noise characteristics of the photodetector based on the signal intensity to calculate a first correction spectrum. Furthermore, it subtracts a correction value from each component value of the measurement spectrum to derive a second correction spectrum, ultimately calculating an output spectrum.

Another aspect of his patent involves a processing unit that obtains a first spectrum and a first signal intensity after the light entering the housing is cut off. It calculates a first correction spectrum by subtracting a first correction value from each component value of the first spectrum. The processing unit also obtains a second spectrum and a second signal intensity while a cut-off portion is opened, calculating a second correction spectrum by subtracting a second correction value. The output spectrum representing the measurement result is derived by subtracting the first correction spectrum from the second correction spectrum.
