Title: Kouji Nishio: Pioneer in Optical Measurement Technologies
Introduction
Kouji Nishio, a distinguished inventor based in Tokyo, Japan, has made significant contributions to the field of optical measurement technologies. With a prolific record of 14 patents, Nishio is recognized for his innovative solutions in measuring the optical characteristics of the human eye.
Latest Patents
Among his latest inventions is an advanced eye's optical characteristics measuring system. This system comprises a target projecting means that projects a target image onto the fundus of the eye under test. It features a photodetecting means to guide the target image toward a photoelectric detector, alongside a pupil diameter measuring means. This invention calculates the optical characteristics of the eye based on the optical intensity distribution obtained from images acquired by the photoelectric detector. The system also includes independently driven aperture selecting means designed to optimize both the projecting luminous flux and the photodetecting luminous flux based on the measured pupil diameter.
Another notable patent from Nishio is also an eye's optical characteristics measuring system, which integrates a first target projection optical system and a first photodetecting means. This invention measures the ocular refractive power by detecting reflections from the fundus of the eye. It utilizes a second target projecting means and a second photodetecting means to acquire multiple images at predetermined refractive degree pitches. Through these innovations, Nishio enhances the accuracy of eye refractive power measurements.
