Use of holographic interferometry for nondestructive testing of materials and components . Holographic interferometry represents a useful tool for measurement of deformations over large surface areas of any constructional or plant components. Application of the stresses encountered in operation reveal weak spots endangering the component owing to improper production methods or to material defects. Furthermore, particularly small material defects can be detected on generation of waves by an impact loading; interference at cracks is clearly displayed in the holographically stored interference picture.
