Seismic exploration demands high temporal-spatial resolution and cost-effective deployment. Distributed acoustic sensing (DAS), an emerging seismic exploring technology utilizing optic-fiber cables, supports intensified real-time observation of geological activities. Phase unwrapping, a critical step in deriving disturbance from DAS raw data, traditionally relies on phase continuity, assuming the original difference between adjacent measurements is less than <inline-formula...
Magnesium alloys have been used to manufacture biodegradable implants, bone graft substitutes, and cardiovascular stents. WE43 was the most widely magnesium alloy. The degradation process begins when alloy stent is implanted in body comes into contact with fluid. products include hydrogen, Mg2+ , local alkaline environment, unsoluble products. A large number of studies focused on pH vitro, vivo alloys, but few corrosion (UCPs). In this study, UCPs were prepared by immersion their effects...
We introduce a 2-D phase unwrapping algorithm to DAS, surpassing dynamic range limits of conventional methods. Considering inter-trace phases, it enhances unwrap ability, mitigating stripe error caused by low SNR.
