Significant advances in optical metrology have fueled the development of new, innovative techniques for the technology in a wide range of applications. Now you can better understand these highly accurate and versatile new methods, and gain insight into applying the technology to solve specific measurement problems. Optical Measurement Techniques and Applications does much more than just cover the underlying principles behind the latest optical measurement techniques. With the help of hundreds of example diagrams and step-by-step equations, sixteen of the industry's leading experts quickly bring you up to speed on how these methods are used in dozens of real-world applications - from laser remote-sensing, to vibration measurement, to providing the data necessary to develop computer models, and more. The book also prepares you to meet future optical measurement challenges by identifying what areas of research are on the horizon. And each chapter concludes with an extensive list of references for more advanced research. This is an invaluable reference for optical researchers and practicing engineers who need sharp insight into the key optical measurement techniques and systems in use today. It's also a powerful learning resource for upper-level undergraduate and postgraduate students.
