【摘要】 利用光纤布喇格光栅的调谐特性,提出一个在光纤光栅调谐范围内对光纤光栅的布喇格波长、波长的漂移以及引起光纤光栅波长漂移的物理量进行检测的方案。采用悬臂梁结构,利用光纤布喇格光栅对的方法增大了光纤光栅的调谐范围。更多还原

【Abstract】 With the tuning characteristic of the fiber Bragg gratings(FBG),a scheme about measuring spectrum of FBG reflection wavelength,wavelength excursion and the variety of matter which causes the wavelength excursion is described.The linear tuning of FBG Bragg wavelength is increased by applying cantilever beam and double-FBG.更多还原
