The integratedDVS is a optical module designed based on Rayleigh back-interference sensing technology, which is the core component of the distributed fiber optic vibration sensing system. Unlike traditional point-type vibration sensors, DVS realizes continuous, real-time. Light scattering happens when light travels through an uneven medium, causing some beams to change direction and scatter from their original path. Scattering can be classified into elastic scattering and inelastic scattering. Elastic scattering mainly includes Rayleigh scattering and Mie. Canovate Group has a unique Distributed Vibration Sensor (DVS) system that is practical and effective in the prevention of oil or gas spills due to its unique ability to detect, locate and classify vibrations caused by physical activity (such as third-party interference), while simultaneously. Ensure provides highly integrated optical solutions for distributed optical fiber vibration sensing (DAS & DVS). Our modules internally integrate Ensure's self-developed ultra-narrow linewidth laser with linewidth <3kHz, AOM, pulse amplifier, and BPD detector, offering comprehensive solutions for. The DVS/DAS Integrated Optical Module is internally designed with a coherent detection optical path for very high sensitivity and signal-to-noise ratio. DFOS systems, including Distributed Temperature Sensing (DTS), Distributed Vibration Sensing (DVS), and Distributed Acoustic Sensing (DAS), utilize.
