Paper Abstract

Holographic interferometry and speckle interferometry are currently used in the field of non-destructive testing. More particularly, they permit to detect defects in structures by analysis of their behavior under stresses. In this work we have studied the possibility of using these techniques for the detection of cracks in reinforced concrete structures. We present some results with classical double-pulse holography and with the double reference technique. We also present some results with speckle interferometry on CCD camera.
