Nondestructive testing of structural components through ultrasonic testing is well established as
one of the industry’s benchmark techniques. Its capability to penetrate both thin and thick
material provides arguably the best information to inspectors on subsurface faults. However,
there are two basic drawbacks to its use: its difficulty to employ and its slow speed. Real-time
C-scan solves both of these issues while maintaining high quality subsurface information Voids,
delaminations, impact damage, and subsurface inclusions can be observed in 1/30 second. The
basis for this technology is a novel two-dimensional imaging array that creates immediate,
high-resolution images of subsurface faults. Real-time C-scan can potentially be applied to any
inspection that now uses ultrasonic inspection. Specific faults that offer a substantial potential
for this technique include subsurface cracking, voids, impact damage, delaminations and
corrosion. The use of semiconductor technology, and standard "optical" techniques such as
lenses to create real time imagery means that commercial systems can be delivered at costs less
than or equal to today’s slower C-scan systems. Through the use of Imperium’s two-dimensional
ultrasound imaging array, manufacturers can implement an on-line imaging technology which
allows for coverage of large composite or metal sheets in a fraction of the time as standard point
by point scanning. Each frame, presented at TV rates or faster, presents a C-scan image over
an area. Image processing performs real time video enhancement such as brightness, contrast,
noise reduction, large montage images, etc. Machine vision software provides "hands off"
processing.
