Full field measurement of guided ultrasonic waves using lensless digital holography and structure function analysis
This work discusses the full-field measurement and characterization of guided ultrasonic waves (GUWs) on technical surfaces. The measurement is realized by a lensless digital holography approach with stroboscopic coherent illumination. This approach ultimately yields the height distribution featuring the deformation caused by the GUWs, which is then statistically evaluated using the structure function. As a result, GUWs are captured single-shot and characterized regarding wavelength and amplitude.
