Our NDT Technology

Laser Technology Inc. offers a unique combination of advanced nondestructive technologies combined with considerable experience and expertise in system integration, robotics, optical systems, fixture and tool design. Our proprietary digital laser Shearography and Holography cameras used for all LTI products and custom systems have exceptionally high resolution and low noise.

LTI Shearography and Holography systems image and measure test object surface profile changes down to 1 nanometer. Subsurface defects cause local changes in the surface profile when the test part is subjected to a change in applied load. Typically these loads are in the form of heat, cold, pressure, vacuum, vibration or electromagnetic energy. These changes in surface profile reveal subsurface defects such as:

  • Disbonds, Unbonds, Delamination
  • Core damage, Core splice disbonds, crushed core
  • Impact Damage, Heat Damage
  • Water Ingress

Laser Shearography NDT technology

Shearography

Laser NDT methods based on interferometric imaging, primarily holography and shearography, have seen growing acceptance since the mid 1980's. With the large increase in the use of composite materials and sandwich structures, the need for high speed, large…

Holography Technology

Holography has been used since the 1970’s for tire inspection. Before the development of electronic holography or electronic speckle interferometer (ESPI) cameras, film holography cameras were used in combination with vacuum stress.
