Abstract

Fiber Bragg grating (FBG) can be embedded in different materials to measure different physical parameters. In this article, the sensors fabricated by FDM technology with an FBG inside and outside the PLA material have been explored. The wavelength shifts of two types of rings have varied within the arm angle ranging from 0° to 75°. The experiment results show that the transmission spectrum of the rings is critically dependent on the placement positions of FBG, and the ring with FBG placed inside PLA materials has larger wavelength shift than that of the FBG placed outside.

摘要

光纤布拉格光栅（FBG）可以嵌入不同的材料中以测量不同的物理参数。本文探讨了采用 FDM 技术在 PLA 材料内外带有 FBG 制造的传感器。两种环的波长偏移在 0° 到 75° 的臂角范围内变化。实验结果表明，环的透射光谱严重依赖于FBG的放置位置，FBG放置在PLA材料内部的环比FBG放置在外部的波长偏移大。
