[0002] Fiber Bragg grating (FBG) sensors are optical sensors based on the principle of fiber Bragg gratings. They achieve high-precision sensing by measuring the wavelength shift of the grating caused by external physical quantities (such as temperature, strain, pressure, vibration, etc.). Due to their advantages such as resistance to electromagnetic interference, small size, corrosion resistance, and strong multiplexing capability, FBG sensors are widely used in aerospace, civil engineering, energy and power, and medical and health fields. However, the performance of FBG sensors (such as sensitivity, stability, and dynamic response characteristics) is significantly affected by the grating structure, packaging process, material properties, and environmental factors. Therefore, a specialized testing device is needed for systematic evaluation. This paper designs a performance testing device for FBG sensor design. Utility Model Content
