Introduction

Bragg Fiber Bragg Grating Sensing and Application Experiment System is specially developed for students in colleges and universities and laboratories to study and research fiber Bragg grating sensing. It aims to introduce the basic characteristics of fiber Bragg grating and the basic principles of fiber Bragg grating sensing. This experimental system is equipped with a high-precision temperature control platform, a multi-functional equal-strength cantilever beam and a fiber grating demodulator (based on a tunable F-P filter), which can complete the sensitivity calibration and distribution of fiber gratings to temperature and micro-displacement.
