Real-Time Terahertz Diagnostics for Detecting Microleak Defects in the Seals of Flexible Plastic Packaging
We present a method of detecting production faults in flexible plastic packages using terahertz (THz) radiation. A focused THz beam is scanned along the sealed area of a package, and the transmitted signal is collected. Defect detection is effected through the large difference between the absorption...
