Description

Holographic Nondestructive Testing presents a unified discussion of the principles and methods of holography and its application holographic nondestructive testing. The book discusses in detail the basic theoretical concepts, the experimental methods for recording holograms, and different specialized holographic techniques. Several kinds of holography are discussed in the beginning chapters such as continuous-wave holography, pulsed holography, and interferometric holography. Other topics covered in the book are holographic surface contouring, holographic correlation, and holographic vibration analysis. Microwave and acoustical holography are the major areas of interest in Chapters 9 and 10. The text serves as an important reference to both engineers and optical scientists.
