' ... the book offers a unique user-oriented approach that will appeal to students, researchers, and practising engineers. It is written very clearly, contains a lot of practical examples, is well illustrated with diagrams and photographs, and each chapter is followed by references. The book is a classical one, but is a welcomed and needed addition to the literature.' International Journal for Light and Electron Optics Cloud has succeeded in developing a single unified text covering the relevant topics in optical metrology...a welcomed and needed addition to the literature and will certainly find a place on the bookshelf of many teachers and researchers working in the area of applied optical measurements in engineering. As intended, a void has been filled. Optical Engineering Cloud's book integrates topics dedicated to both coherent and white light techniques in one volume. Applied Mechanics Reviews
