Abstract
Holography is basically a two-step process for creating a whole three dimensional image of a diffusely reflecting object having some arbitrary shape. This article discusses the advantages, disadvantages and applications of using the optical holography method in nondestructive evaluation. It also discusses the types of acoustical holography, including liquid-surface acoustical holography and scanning acoustical holography. The article concludes by comparing liquid-surface and scanning systems.
