High-Speed 3D Imaging with Digital Fringe Projection Techniques

Song Zhang earned his BS from the University of Science and Technology of China, and his MS and PhD in mechanical engineering from Stony Brook University. He then spent three years in the Mathematics Department at Harvard University before joining Iowa State University as an assistant professor of mechanical engineering. He recently moved to Purdue University, where he is currently an associate professor of mechanical engineering. A widely published and highly decorated SPIE fellow, Professor Zhang is often credited with developing the first-ever high-resolution, real-time 3D optical imaging system. Besides being extensively utilized in academia, the technologies Professor Zhang has developed have been used by the rock band Radiohead to create a music video for the 2007 song "House of Cards," and by Zaftig Films to produce the 2015 movie Focus.

"... 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."—Qian Kemao, Nanyang Technological University, Singapore"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."—Laurence G. Hassebrook, University of Kentucky and Huntsbrook Inc., Lexington, USA"... 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."—Xianyu Su, Sichuan University, Chengdu, China
