The video-based frequency measurement method for bridge cable vibration offers advantages such as speed, efficiency, and noncontact compared to traditional sensor-based methods. However, the presence of complex backgrounds in video images can affect accuracy measurement. To address problem, a novel phase-based is proposed, which focuses on extracting edge from background noise spatial temporal domains. First, domain, process signals more precisely, each sequence divided into multiple...
Back-n is a white neutron experimental facility at China Spallation Neutron Source (CSNS). The time structure of the primary proton beam make it fully applicable to use TOF (time-of-flight) method for energy measuring. We implement electronics measurement on general-purpose readout designed all seven detectors in Back-n. based PXIe (Peripheral Component Interconnect Express eXtensions Instrumentation) platform, which composed FDM (Field Digitizer Modules), TCM (Trigger and Clock Module), SCM...
The video sensor-based method for bridge cable frequency measurement offers notable advantages in terms of speed, efficiency, and noncontact compared with the conventional acceleration sensor approach. However, accurately measuring cable's microvibration under natural excitation remains a challenge method. To address problem, novel phase-based method, named EnhancedPVE, is proposed, which leverages signal characteristics difference between noise temporal spatial domains without necessity...
Ground Penetrating Radar (GPR) is an efficient remote sensing tool for geophysical subsurface survey. These structure characteristics are recorded in radar signal profiles by means of echo detection, amplitude and phase estimation. Besides the energy attenuation absorption GPR EM pulse during its propagating downward direction into ground from a transmitting antenna, strong interferences, clutters, multiples random noise, often make fine-structures hardly distinguishable. This paper develops...
