Statistical Analysis of Ultrasonic Reflector Response
The sensitivity of ultrasonic testing system depends on many factors that should be adequately selected for precise reflector characterization. In this paper several factors were analyzed in order to show how their interactions influence variability of results. We utilized two-level three-factor design of experiments. The three factors selected and varied were probe frequency bandwidth, probe response damping and pulse energy. The experiment design enabled us to determine which factor and which interaction has the most significant influence on the reflector size evaluation. The underlying ultrasonic technique was the pulse echo technique in which the differences in gain between infinite reflector and disc reflector (DELTA) were determined. The bandwidth was revealed as the most influential among the three factors considered.
