Outline of Final Research Achievements

We improved the block-type optical devices so that those can be used as a teaching material for distance education involving experiments. The block-type optical devices are novel optical experimental teaching materials that allow students to intuitively understand its function. Those are easy to handle, small, lightweight, and inexpensive to provide. To protect the surface of the element, we developed a non-polarizing protective sheet using a thin resin plate. We also increased the toughness of the element and improved the method of fixing it to the base that mounts it. The effectiveness of the non-polarizing protective sheet and the new element fixing method were confirmed in various experiments, including an experiment to confirm the principle of an optical pickup.

Academic Significance and Societal Importance of the Research Achievements

新型コロナウィルス感染症の拡大を契機として遠隔教育は広く普及したが，実験・実習系の科目は実施に困難が伴うのが現状である。理系の高等教育において，例えば電子・情報系の分野では，情報処理・電子回路・ディジタル技術などにおいては遠隔教育に対応させることができる実験・実習教材が存在している。しかし，光技術においては，広く利用されている市販の光学実験機器が高精度な調整が必要で，サイズが大きく重量もあるため，そのような実験教材は存在しなかった。本研究は，それに道を拓くものである。
