Design and Construction of an ultrasound transmit pulser system for non-destructive testing

Abstract

The design and construction of an ultrasonic pulser is part of a multichannel ultrasonic system, for the analysis, monitoring and characterization of heterogeneous and highly dispersive materials. The pulser has been built on the FPGA platform and allowed to modify the pulse repetition rate, the pulse width and the number of pulses of a burst. This open architecture is a basic module for a more complex ultrasonic pulser, such as arbitrary pulse generator. The results show the ultrasonic transducer responses under the above parameters.
