FBG Triaxial Accelerometer
简要描述： The fiber Bragg grating accelerometer transmits acceleration changes to the fiber Bragg grating through proper encapsulation. Combined with high-speed fiber Bragg grating demodulation technology, acceleration is calculated by measuring the wavelength shift of the fiber Bragg grating. Fiber Bragg grating sensing technology offers small size, high sensitivity, and high reliability, enabling long-term operation in harsh environments. Additionally, the sensor can be assembled with different structures to enable two-dimensional and three-dimensional acceleration measurements. It is suitable for vibration monitoring of engineering structures such as engines, generator pumps, bridges, and roadbeds.
