ABSTRACT:
In a method of inspecting a structure, a two-dimensional array of sensors is disposed onto a surface, ultrasonic pulses are sent into the surface, and echo signals are received. An image of damage within the structure is graphically displayed, a determination of whether the damage satisfies a predetermined criterion is made, and a mode of returning the structure to usage or service is selected. The predetermined criterion may define a length, a depth, and an area. A-scan, B-scan, and C-scan images of the damage may be displayed. Threshold images may be displayed wherein each pixel of a matrix of pixels is colored one of only two colors.
