Non-Destructive Test (NDT) with Terahertz

Handheld terahertz sensors can measure and scan specialty coatings and multilayer structures to check thickness consistency and locate subsurface detects. For example, terahertz systems can be used to inspect the high-performance coatings used on military aircraft, verifying thickness of applied coatings with submicron accuracy. Terahertz measurements are also useful for aiding the in-service inspections and repairs of external coating.

Industry Application Area
Aerospace
  • Coating thickness
  • Panel alignment
  • Defect identification
Marine
  • Coating thickness
  • Corrosion under paint
Building Products
  • Seam inspection
  • Void detection
Petrochemical
  • Coated steel pipe
  • Pipe repair inspection

Terahertz measurement systems are also able to verify the structure of multilayer materials with a single sensor.  A terahertz system outfitted with a line scanner gauge can produce B-scan images of defects, subsurface structures or provide precise offset and separation measurements.
