of that found in Chapter 7 in I. Laser ultrasonic techniques have been investigated by many researchers and practitioners since the early work by White. The theory and application of laser ultrasonic NDE are presented here in a comprehensive manner with extensive references. Brillouin light scattering is also a noncontact technique to measure elastic properties of material. A comprehensive review of this technique, which
is particularly suited for measurements of elastic anisotropic bulk properties of small samples and anisotropic properties of thin films, is presented in Chapter 10 (by M.C. Beghi, A.G. Every, V.B. Prakapenka, and P.V. Zinin). This is an updated version of Chapter 10 in I. A brief review of bulk and surface waves in anisotropic solids is presented in this chapter. Exten- sive references are given to guide the readers to the published literature.
Chapter 11 (by P.V. Zinin, W. Arnold, W. Weise, and S. Berezina) provides a review of the theory and application
of scanning acoustic microscopy and imaging by acoustic microscopy. Since the development of acoustic microscopy for imaging near – surface microstructure of opaque materials and defects in the 1980s and 1990s, there have been many improvements in the technology that allow characteriza-
tion and imaging of two and three dimensional sub-surface features in isotropic and anisotropic materials. This review, which is an expanded version of the review in I, discusses the theory and applications of this technique for imaging of engi- neering and biological materials. This chapter contains many illustrative examples and figures. Extensive references are also given for the reader to learn and explore the technique.
Characterization of mechanical properties of biological mate- rials and their mechanical behavior have been investigated by many researchers since the 1970s. Ultrasonic characterization of biological materials, like cells and bones, has been under active investigation since the 1980s. The advances in acoustic microscopy have enabled researchers to measure mechanical properties and to image them. Chapters 12 (by C. Blase and J. Bereiter-Hahn) and 13 (by K. Raum) deal with these top- ics. Modeling and measurement issues are well reviewed with
many references in these chapters. Clinical applications of ul- trasound are also treated in Chapter 14 (by Y. Saijo). This is a good review of the developments in medical ultrasound since the 1940s. The readers of this book will find these chapters very informative and useful in their work.
Terahertz radiation and its uses have been the subject of intense investigation in the last two decades or so. A recent book by Y.-S. Lee gives a good description of terahertz science and technology. Chapter 15 (by E.K. Rahani and T. Kundu) reviews some applications of terahertz technology in non-de- structive evaluation of solid foam and heat–treated materials. Both time and frequency results are presented. Modeling by the DPSM (see Chapter 4) and applications to heat damaged block material are discussed. This review will be useful to stu- dents and researchers interested in this interesting technology.
Assessment of damage state and failure prediction of aeronau- tical/aerospace, civil, and mechanical structures in use have become critically important problems worldwide. There are many ongoing efforts to develop efficient sensing technolo- gies. Chapters 9 (by A. Rakow and F.-K. Chang) and 16 (by N. Takeda, Y. Okabe, and S. Minakuchi) describe develop- ments in two technologies: embedded eddy current sensors for bolted joints and fiber; optic sensors for fiber reinforced composites. The authors present theory and applications in details for the readers to appreciate the challenges involved and opportunities for significant advancement. Adequate references are included for further exploration.
Overall, some of the chapters in this book are a good refer- ence source of information on the state–of–the–art of current researches. They will be very useful to graduate students and researchers. But not all the chapters are equally comprehen- sive. Rather, they are specialized to particular techniques or problems and thus, are narrow in scope. This gives the book an uneven character. In spite of these deficiencies, though, the book is a valuable addition to the literature on nondestructive evaluation of materials and structures.
