Title: Hiroshi Watanabe: Innovator in Optical Measurement Technologies

Introduction

Hiroshi Watanabe is a prominent inventor based in Utsunomiya, Japan. He has made significant contributions to the field of optical measurement technologies, holding a total of 11 patents. His work has advanced the understanding and application of optical scales and encoders.

Latest Patents

One of his latest patents is focused on a displacement-measuring optical scale and an optical encoder utilizing the same technology. This invention involves a convex lens that approaches the 0-th order transmitted light during the rotation of an optical scale. The 0-th order transmitted light, derived from a light beam emitted from a light source and transmitted through a diffraction grating, is converged and directed onto a reference position signal detection sensor. This process yields a substantial output from the sensor, which constitutes a reference position signal. Additionally, reflective diffracted light beams, which have been reflected by the diffraction grating, are detected by a diffraction light detection sensor after interference. This allows for the detection of the speed and angle of the scale. Consequently, both the reference position signal and an incremental signal are detected at the same position on the optical scale.

Career Highlights

Hiroshi Watanabe has worked with notable companies such as Canon and Intermetallics Co., Ltd. His experience in these organizations has contributed to his expertise in optical technologies and innovations.

Collaborations

Throughout his career, Watanabe has collaborated with esteemed colleagues, including Hiroyuki Hagiwara and Shojiro Yamazaki. These partnerships have fostered a creative environment that has led to groundbreaking advancements in his field.

Conclusion

Hiroshi Watanabe's contributions to optical measurement technologies are noteworthy and impactful. His innovative patents and collaborations reflect his dedication to advancing the field. His work continues to influence the development of optical scales and encoders, showcasing the importance of innovation in technology.
