Title: The Innovative Contributions of Koji Kojima

Introduction

Koji Kojima is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of light measurement technology. His innovative approach has led to the development of a unique patent that enhances the understanding of light distribution.

Latest Patents

Koji Kojima holds a patent for a "Method and apparatus for measuring the distribution of a light field." This invention involves a video signal produced by capturing the light image projected onto a screen. The signal is quantized using multiple voltage comparators grouped in pairs, each applied with different reference voltage levels. One output from each pair of comparators is inverted in an orderly manner and synthesized with the remaining outputs. This process generates a dark and bright stripe signal, which is displayed on a video device to create a radially discrete annular pattern that represents equibrightness curves. This innovative method allows for more accurate measurements of light distribution.
