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 ...

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 ...

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 ...

Aerospace, automotive and airplane construction count on lightweight construction. But to make sure that lightening the load does not come at the cost of safety, Fraunhofer researchers are working on ...

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 ...

Everything has a quality control process to ensure its safety and integrity. Everyday items and large infrastructure are continually subjected to wear and tear, causing damage and erosion, while the ...

Aerospace, automotive and airplane construction count on lightweight construction. But to make sure that lightening the load does not come at the cost of safety, researchers are working on new quality ...

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 ...
