Title: Shigeru Yamada: Innovator in Measurement Technology

Introduction

Shigeru Yamada is a notable inventor based in Chofu, Japan. He has made significant contributions to the field of measurement technology, holding a total of 3 patents. His work focuses on innovative methods for accurately measuring various physical properties.

Latest Patents

One of Yamada's latest patents is the "Droplet shape measuring method and apparatus." This invention allows for the accurate measurement of shape features of minute droplets arranged on a substrate. By perpendicularly irradiating the substrate with laser light, diffracted light fluxes generated during the passage of the laser light through the droplet interfere with each other, resulting in a diffraction pattern. This pattern is captured by an image pickup apparatus, enabling the measurement of the droplet's shape feature using the resultant diffraction pattern and the droplet's refractive index.

Another significant patent is the "Multi-direction distance measuring method and apparatus." This method involves directing a light beam to an object and scanning it. The reflected light beam is condensed, and a sensor is positioned to receive this reflected light. The distance to the object is determined based on the position of incidence of the reflected light beam on the sensor's light-receiving surface. An apparatus utilizing this method is also provided.
