LTI Shearography and holography system image defects over the entire field of view in real time as the applied load changes. Images are in JPEG, TIFF or other formats and are displayed for operator interpretation or evaluated automatically using ADR (Automatic Defect Recognition software). Many LTI systems also include automatic image stitching to create an image file of the entire part for rapid comparison to CAD or CATIA files.
Inspection throughputs for our automated Shearography systems are as high as 1,000 sq. ft/hour. Testing is non-contact, non-contaminating.

  • Shearography measures changes in surface profile as small as 1 nanometer when the test part is stressed.
  • Real-Time imaging of subsurface defects.
  • Non-Contact, Non-contaminating.
  • Detects and measures Impact Damage & Disbonds.
  • Differentiates between damage and repairs.
  • Large increase in aerospace composite manufacturing productivity.
  • Tests parts 3-100 times faster than UT C-Scan.
  • Test parts during build up- allowing repair or scrapping part at lowest possible cost.
  • Test otherwise uninspectable parts and structures.
  • No requirement for surface following software ( Multi axis).
  • Reveals weak areas and kissing bonds undetected by Thermography.
  • Core damage, Core splice disbonds, crushed core.
  • Impact Damage, Heat Damage.
  • Water Ingress. 
  • Missile, Rocket and Spacecraft components 
  • Aircraft and Aircraft Engine Engines
  • Aerospace, Automotive and Marine Composites
  • Electronics
  • Coatings
  • Repair
