Optical techniques are usually applied inside laboratories equipped with temperature, humidity and vibration control. These techniques are very suitable for fast measurements due to their noncontact nature and their capability to measure on surfaces without special, time-consuming preparation. Among them, optical methods based on the speckle phenomenon have developed substantially over the last two decades due tothe development of digital image processing, digital cameras, computers, lasers, and optical components. However, applying speckle methods outside of the laboratory becomes a challenging task. This book presents techniques and tools that will enable the development of robust measurement instruments to be used outside the laboratory for nondestructive structural-integrity-evaluation devices. Additionally, several technical solutions that combine mechanical systems to solve industrial measurement demands are described.Abstract: Presents techniques and tools that will enable the development of robust measurement instruments to be used outside the laboratory for nondestructive structural-integrity-evaluation devices.Additionally, several technical solutions that combine mechanical systems to solve industrial measurement demands are described.
