主讲人简介:

益田正，日本静冈理工科大学名誉教授。在大学工作期间，他从事角度检出器超高精度校正法和建筑行业自动机械开发方面的研究。提出了一种无需使用高精度基准即可实现旋转编码器超高精度校正的独特方法，并制定校正系统对其进行了验证。之后，他致力于此技术的推广普及，最终使该方法成为日本角度跟踪的国家标准（±0.02角秒），并以此建立了日本角度精度追踪系统。此外，他还参与了日本国立天文台电波望远镜用超高精度角度传感器（±0.1角秒）的开发工作。

目前，他的方法已被许多旋转编码器制造商采纳为标准，9个国家也将该法作为国家标准普及使用。近期，世界最高水平的旋转编码器（±0.036角度秒）已利用该技术被开发出来。同时，他还开发了与建筑行业相关的机器人。研究成果曾获得日本文部科学大臣奖表彰以及日本精密工学会奖。

Introduction to Expert:

Masuda Tadashi is the honorary professor at Shizuoka Institute of Science and Technology in Japan. During his university work, he engaged in research on ultra high precision correction methods for angle measuring instruments and the development of automatic machinery in the construction industry. His achievement is to propose a unique method for achieving ultra high precision calibration of rotary encoders without the use of high-precision benchmarks, and to develop and validate a calibration system. Afterwards, he devoted himself to the popularization of this technology and finally made this method the national standard for angle tracking in Japan (± 0.02 angle seconds), establishing the Japanese angle accuracy tracking system with this as the vertex. In addition, he has also been involved in the development of ultra-high precision angle sensors (± 0.1 angle seconds) for the radio telescope at the National Astronomical Observatory of Japan.

At present, his method has been adopted as a standard by many rotary encoder manufacturers, and 9 countries have also popularized the use of this method as a national standard. Recently, the world's highest level rotary encoder (± 0.036 angle seconds) has been developed using this technology. At the same time, he also developed robots related to the construction industry. He has been recognized for his research achievements by the Minister of Education, Culture, and Science of Japan, as well as the Japan Institute of Precision Engineering Award.
