Damage Detection Using Holography and Interferometry

  • Arthur J. Decker


Some major goals of structural testing are the detection of local damage and, more recently, the general evaluation of structural health. Detection of local damage calls to mind several specialized practices. The most direct is simple visual inspection for cracks or visual inspection perhaps enhanced by dye penetration. This simplest of approaches is augmented by a variety of visualization techniques. These include,1 for example, X-ray radiography; neutron radiography; ultrasonic techniques including C-scan imaging; optical, electron and scanning probe microscopy; eddy currents; both optical and non-optical thermography and the interferometric methods to be discussed in this chapter.
