Abstract
A great deal has been written about holography, especially in the years since Gabor won the Nobel Prize (1971) for his "invention and development" of the method. While it is fairly safe to state that the movie and T.V. industries are not on the verge of a revolution as a result of the highly touted three-dimensional characteristics of the process, it can be said that holography may offer considerable scientific potential in such diverse areas as computer storage, display systems, correlation techniques, medical diagnostics (acoustical holography) and radar (microwave holography), to mention just a few. Another promising application of holography, and one that has been given considerable attention at United Technologies Corporation and other industrial laboratories, is nondestructive testing. Consideration shall be given to this subject in the present paper by starting with a very brief review of holography (The Basic Tool), followed by a description of interferometric hologra-phy (Preparing the Tool for Use), and how it can be employed to nondestructively identify defects (Applying the Tool). This sets the stage for two final topics which establish the holographic process as a viable NDT technique: pulsed holography (Adapting the Tool to the Industrial Environment) and special HNDT techniques (Simplifying and Diversifying Tool Application).
