Title: Inventor Hiroyuki Nagahama: Pioneering Innovations in Displacement Measurement
Introduction
Hiroyuki Nagahama is a distinguished inventor based in Tokyo, Japan, known for his contributions to technology and innovation. With a remarkable portfolio of 11 patents, he has demonstrated a profound impact in the fields of measurement and inspection apparatuses.
Latest Patents
Among his latest innovations are the displacement measuring apparatus, electron beam inspection apparatus, and displacement measuring method. The displacement measuring apparatus is particularly noteworthy; it features an illumination system designed to obliquely irradiate the surface of the target object with beams. The apparatus employs a sensor to capture the reflected light, coupled with an optical system that diversifies this light within a Fourier plane. A camera is then used to image the diverged beam, while gravity center shift amount calculation circuitry computes the gravity center shift from the measured light quantity distribution. This information enables the measurement circuitry to accurately determine heightwise displacement of the target object surface using the optical lever method, based on a corrected gravity center position.
