单根光纤布拉格光栅横向受力自动判断研究
Study on Automatic Judgment of Transverse Force of Single FBG
摘要: 单根光纤布拉格光栅在一定的横向压力下中心波长处的光功率大小及中心波长会发生人眼能判断的变化。通过编写代码来读取光谱仪输出的数据，程序代码对输出的数据进行可视化并且和未受到横向压力时的光纤光栅光谱进行对比，在对受到横向压力光纤光栅的中心波长处的光功率和未受到横向压力光纤光栅中心波长处的光功率进行比较大小，可识别出受力光栅和光谱仪显示的受力的光栅结果一致，此结果与光栅已受力的实际情况相符。
Abstract: Under certain lateral pressure, the optical power and central wavelength of a single fiber Bragg grating at the central wavelength will change as judged by the human eye. The output data of the spectrometer is read by writing code. The output data are visualized by the program code and compared with the spectrum of the fiber grating without transverse pressure. The optical power at the central wavelength of the fiber grating under transverse pressure and the optical power at the central wavelength of the fiber grating without transverse pressure are compared. The results of the stress grating and the grating displayed by the spectrometer are consistent, which is consistent with the actual situation of the grating.
