Abstract
In this study, we studied the gamma-radiation effect of fiber Bragg gratings (FBGs) manufactured by array sensors. The array FBGs were fabricated in a different Bragg wavelength using the same commercial Ge-doped fiber and exposed to gamma-radiation up to a dose of about 100 kGy at the dose rate of 113 Gy/min. It was analyzed radiation effects by measuring the radiation-induced change in the temperature sensitivity coefficient and Bragg wavelength shift after irradiation.
본 논문에서는 배열형 센서로 제작된 광섬유 브래그 격자(FBG)의 감마방사선 영향을 분석하였다. 배열형 FBG는 동일한 상용 광섬유를 이용하여 서로다른 브래그 파장으로 제작되었다. 제작된 FBG는
