Dear aspearin1: Weld flaws and voids can be detected with laser optical inspection systems. This technique has proven success especially if composite materials and/or joints are concerned. You might have a look at www.dantec-ettemeyer.com and follow the link to the NDT product lines. They...

Dear feajob: I am with a company that manufactures measuring systems for optical full-field strain and stress analysis. This is a 3-D non-contact measurement. They enable fast acquisition of the strains and stress in the observed surface section with regard to magnitude and direction. In...

Dear gwolf: I am with a company that manufactures measuring systems for optical full field vibration analysis. They are into non-contact measurements of 3D deformations and strains. This technique might also make the use of strain gauges obsolete in your application. And the contactless...

Dear wongweiyew: I am with a company that manufactures shearography based systems for non destructive testing. Shearography has some advantages over traditional NDT technologies especially if composite materials and/or joints are concerned. They have performed a wealth of contract measurements...
