초록
본 논문에서는 800nm급 펨토초 레이저를 이용하여 FBG 센서를 제작하였다. 제작된 센서는 누적 방사선량 100kGy 감마선에 조사하였고, 광섬유 코팅재료에 따른 방사선 영향을 평가하였다.
In this paper, FBG sensor is fabricated using 800nm femtosecond laser. The sensor was irradiated with a cumulative dose of 100 kGy gamma ray, and the effect of radiation on the FBG coating material was evaluated.
