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.
LTI-5100 Shearography System featuring
built-in laser, image processing
computer and remote control console.
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:
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.
LTI
Shearography Systems provide process
control in the manufacturing of
large composite structures by
allowing fast, non-contact inspection
as well as NDT of repairs. Applied
to aerospace composites, parts
are tested on the tool between
ply build up ensuring low scrap
and high productivity.
LTI
has developed and patented many
unique Shearography and Holography
stressing methods and data acquisition
techniques useful for nondestructive
testing of a broad range of materials
and structures.
Applications
include:
•
Missile, Rocket and Spacecraft
components •Aircraft
and Aircraft Engine Engines
•
Aerospace, Automotive
and Marine Composites •
Electronics •
Coatings •Repair
