Innovative Systems Design and Engineering
A USB based Ultrasonic Data Acquisition and Analysis System
Abstract
The research aims at weakness and diversity characteristics of electromagnetic ultrasonic signals and demand of portable devices based on electromagnetic acoustic transducer and designed an electromagnetic ultrasonic data acquisition system. Data exchange between computer and acquisition circuits was realized through USB interface. Controls of electromagnetic ultrasonic transmit/receive circuits and acquisition of echo data were implemented utilizing Atara FPGA. Software was developed by Labview. Experiment showed that the system is efficient enough for generating acquisition data.
