Design of Signal Acquisition and Processing System for Laser Doppler Vibrometer
摘要
Abstract
A visual data acquisition and processing system is presented to satisfy the signal processing specifica -tion 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 forsampling.VC ++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-timeperformance and high integration, this data acquisition and processing system realizes the real -time acquisition andprocessing of the output signals of LDV and meets the demand of topographic mapping under the hydrodynamic watersurface.关键词
