| Abstract: | A visual data acquisition and processing system is presented to satisfy the signal processing specification of the laser Doppler vibrometer (LDV) working for the optic-acoustic remote sensing of the shallow terrain and to resolve the questions of low sampling rate,inconvenient man-machine interface and the less number of channels for sampling.VC+KG-1.5mm]+ is employed in the post-development of PCI5616 to achieve real-time display,acquisition,storage,and real-time data-processing of the signals.With good processing capacity,flexible operation,good real-time performance and high integration,this data acquisition and processing system realizes the real-time acquisition and processing of the output signals of LDV and meets the demand of topographic mapping under the hydrodynamic water surface. |
