Digital fringe projection (DFP) techniques are used for non-contact shape measurement of 3D images. In the rapidly expanding field of 3D high-speed imaging, the demand for DFP continues to grow due to the technology’s fast speed, flexibility, low cost, and high accuracy.
High-Speed 3D Imaging with Digital Fringe Projection Techniques discusses the generation of digital fringe with digital video projection devices, covering a variety of core technical aspects. The book begins by establishing the theoretical foundations of fringe pattern analysis, reviewing various 3D imaging techniques while highlighting the advantages of DFP. The author then:
Incorporating valuable insights gained during the author’s 15+ years of 3D imaging research, High-Speed 3D Imaging with Digital Fringe Projection Techniques illuminates the pathway to advancement in high-speed 3D optical imaging using DFP.
"… a timely publication that comprehensively describes digital fringe projection techniques for 3D surface measurement and guides you to the research frontier in a friendly manner. You will be eager to develop such a system or improve your own system by testing the exciting ideas presented in the book. The book also precisely 'measures' the author’s enthusiastic pursuit of research excellence."

"I have long awaited a textbook devoted to structured light illumination (SLI), and Song Zhang has fulfilled that wish with a well-written and thoughtful discussion of the theory, technology, and implementation of SLI. SLI has been the workhorse of precision non-contact industrial measurement, but has been overshadowed by the popularity of stereo vision in entertainment markets. I believe Song Zhang’s work will bring SLI to the forefront of non-contact measurement."

"… presents a solid background in the theory and many algorithms used for 3D fringe projection methods with the addition of very practical information on fringe projection hardware, system design, and calibration that are needed to make a reliable system. Many topics covered in the book are often overlooked in publications, but are essential for making a system that produces meaningful 3D data over just pretty pictures. … This book fills an important gap between the vast published material on phase shift analysis done primarily for interferometry and puts the tools in perspective for pattern projection triangulation methods."
—Kevin Harding, Fellow and Past President of SPIE
"Both the theoretical analysis and algorithm development proposed in this book are useful for researchers and engineers, and can serve as specialized topics for students in optical and computer engineering. In the book, the description and discussion are excellent. … The author has produced a comprehensive reference with a concentration on the principles, techniques, and applications. … This is one of the finest books on high-speed 3D imaging with fringe projection."
