Abstract
A Fiber optic strain sensor for the measurement of the internal strain of a concrete specimen was developed. This sensor was a 11 mm Fiber-optic Fabry-Perot interferometer attached inside a stainless steel pipe of 2 mm diameter. The fabricated strain sensors were embedded in a reinforced concrete structure of
콘크리트 구조물의 내부 변형률을 측정할 수 있는 광섬유 간섭계 센서가 개발되어졌다. 광섬유 간섭계 센서는 11 mm 길이의 광섬유 Fabry-Perot 간섭계를 2 mm 지름의 스텐레스 강관 내부에 접착제로 고정하여 만들었다. 제작된 변형률 센서들은
