The S-scan image created during a phased array inspection displays the full sound
path (as defined by [RANGE]) for each angle within the focal law range (sweep). This
S-scan image is drawn on the display as a to-scale representation of the angular
coverage within the test piece.
For example, a 70° focal law is drawn within the S-scan display window at 70° from
vertical. This allows you to visualize reflections from the S-scan as if viewing a cross-
section of the test piece.
