Title: **Yoshiyuki Tomita: Innovating the Future of Sensor and Stage Devices**

Introduction

Yoshiyuki Tomita is a prominent inventor based in Hiratsuka, Japan. With an impressive portfolio consisting of 14 patents, he has made significant contributions to the fields of sensor technology and precision movement devices. His latest innovations focus on enhancing the accuracy and manufacturability of sensor and stage devices, reflecting his dedication to advancing technological applications.

Latest Patents

Among his recent patents, two notable inventions stand out: the sensor device and the stage device. The sensor device is designed to detect the state of a movable stage using a reference grating that is easily manufacturable. This configuration allows it to improve detection accuracy. The device utilizes a light source to emit light directed at the reference grating, which has a two-dimensional periodically varied configuration. A spectral unit transforms this light into multiple beams, enabling a photodetector to receive and analyze reflected light, thus determining the state of the movable body.

The stage device, on the other hand, aims to achieve high-precision movement in both X-Y directions and rotation through the use of a planar motor. By incorporating a scale unit with an extensive scale part on the base and equipping three two-dimensional angle sensors on the movable stage's bottom, this invention facilitates accurate position measurement. Together, these components form a surface encoder that ensures precise movement and size optimization of the stage device.
