Calibration of ultrasonic hardware for enhanced total focusing method imaging [PDF]
Insight - Non-Destructive Testing and Condition Monitoring, 2020 Experimental variation from ultrasonic hardware is one source of uncertainty in measured ultrasonic data. This uncertainty leads to a reduction in the accuracy of images generated from these data. In this paper, a quick, easy-to-use and robust methodology is proposed to reduce this uncertainty in images generated using the total focusing method (TFM).
