Description

Digital data acquisition and the C-scan imaging of ultrasonic data offer improvements over analog recording techniques, such as strip-chart recording. As a result, peak-detected C-scan imaging is becoming the preferred method for the inspection of large titanium parts such as those found in the aircraft engine industry. The effectiveness of the inspection, however, still depends on the transducer. For this reason, a study of the effect of different transducer parameters on the sensitivity for detection of simulated defects in titanium specimens was conducted. Due to the increased emphasis on C-scan imaging, sensitivity is measured as an image-based signal-to-noise ratio.
