The same as the traditional optical interference technique, shearography obtains the object deformation information by obtaining the phase, and the measured object is often dynamic in practical ...

Digital shearography is an optical interferometric technique that measures surface strain by comparing two speckle patterns displaced laterally relative to one another. By analysing the phase ...

Before non-destructive testing came on the scene some years ago, the best and most dedicated inspectors in a retread plant could only inspect tires visually. While they might have had the brightest ...

Shearography equipment well suited to composites NDT CAMX 2025: Laser Technology Inc. features analysis tools like the LTI-2100 and LTI 5200, which are optimal for detecting subsurface composite flaws ...

As the newest generation of composites-intensive aircraft comes online — notably Boeing's 787, and Airbus' A380 and A350 — nondestructive testing (NDT) of composites will assume unprecedented ...

CREECH AIR FORCE BASE, Nevada — Nondestructive inspection technicians assigned to the 432nd Maintenance Squadron at Creech Air Force Base, Nevada, are among the first Airmen to receive training on a ...

ST. LOUIS (April 13, 2009)—Community Tire Retreading is beefing up its OTR tire retreading capabilities, adding the world's largest shearography inspection unit and a curing press capable of handling ...
