We have constructed a system that measures the reflection wavelength of fiber Bragg gratings (FBG) with a wavelength-swept light source that has a variable sweeping frequency. This paper describes the development of a flexible system in which the temporal resolution of measurement can be set arbitrarily down to 0.2 ms and demonstrates that the system is capable of measuring the reflection wavelengths of multiple FBG at high speed over long periods of time.本誌: 電気学会論文誌A（基礎・材料・共通部門誌） Vol.135 No.12 （2015） 特集：スマートな社会を支える最新計測技術本誌掲載ページ: 756-761 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejfms/135/12/135_756/_article/-char/ja/ Show more
