【Abstract】 Data acquisition and processing of ultrasonic equipment was different for the variation of workpiece thickness in ultrasonic testing. A data acquisition and processing method with field programmable gate array(FPGA) was proposed, which could improve the data acquisition and processing speed of the whole ultrasonic testing system greatly.更多还原
