Description

Speckle Metrology presents a diverse and wide collection of metrological speckle techniques and applications. The book discusses both theoretical concepts and experimental methods in speckle-based measurements. Some chapters introduce speckle terminology and the physical characteristics of speckle. Other aspects also covered in the book include methodology, system geometries, data reduction procedures, and specific applications. These applications are discussed in detail in individual chapters, such as structures inspection. Adaptation of speckle measurement techniques in video recording and processing technology is also given emphasis in one chapter. Finally, one chapter is dedicated to a discussion on the speckle interferometer as one of the most used instrument in metrological speckle application. This text is a valuable reference to students in the fields of engineering and applied science.
