An advantage of laser-ultrasonic (LUS) compared to standard ultrasonic is LUS\u2019 capability of easily acquiring data from contoured or complex-shaped parts (relaxed normalcy requirement). Back in early 2000, laser-ultrasonics was considered a serious candidate for a broad range of industrial inspections of aerospace carbon fiber reinforced polymer (CFRP) parts. Further development in phased-array sensors and robotics has reduced the need for LUS in such markets. However, there is still a niche for LUS on highly contoured parts.<\/p>\n
A paper from 2018 by researchers at the Centre Spatial de Li\u00e8ge shows the use of a robotic-based LUS system for the inspection of CFRP aerospace parts. By recording the probe\u2019s position in 3D space for each acquired laser-ultrasonic waveform, a 3D ultrasonic image, known as a C-scan, of the part can be displayed. Such an image is particularly interesting when inspecting a curved shaped part, as shown in figure 5 of the paper. Nice images indeed.<\/p>\n
