The document describes B-Scan profiles generated by an inspection machine. A B-Scan profile shows the thickness of an inspected object along its length based on multiple A-Scan measurements. Sample 1 is a B-Scan of a 6.5mm thick course over 1850mm, while Sample 2 is a 9mm thick course over 1650mm and detected a 2.7mm deep defect spanning 27mm between 1397-1424mm.
