DVS

Ideal-Photonics's DVS system uses the optical fiber itself as a sensor to feedback the vibration, temperature, stress and other variables at different positions, and achieve precise positioning. At present, this distributed sensing technology has been used in long-distance natural gas and oil transmission leakage monitoring, safety monitoring of large buildings such as bridges, and large-area security systems. We adopted the φ-OTDR technology to build the DVS system, using the direct detection method, and passed the pzt vibration test with the simple structure、 high sensitivity and excellent SNR.
