This comprehensive guide presents the latest advancements in Digital Fringe Projection (DFP) technology for non-contact 3D shape measurement. Building upon the foundational knowledge established in the first edition, this expanded volume incorporates significant technological developments from nearly three decades of the author's research. High-Speed 3D Imaging with Digital Fringe Projection Techniques, Second Edition serves as both a theoretical reference and practical implementation guide, featuring detailed illustrations, mathematical frameworks, and step-by-step procedures for building complete 3D imaging systems from scratch. Readers will gain mastery of cutting-edge DFP techniques through newly introduced topics including advanced phase unwrapping methods, binary pattern optimization, pixel-wise calibration for superior accuracy, and innovative approaches to autofocusing using electrically tunable lenses (ETLs). The second edition also covers practical solutions for auto-exposure control and high dynamic range (HDR) imaging, enabling measurement across challenging surface conditions. Each chapter provides theoretical foundations alongside practical implementation guidance, allowing readers to apply these techniques immediately in their own research or industrial applications. This book is ideal for researchers, engineers, and graduate students working in optical metrology, computer vision, mechanical engineering, and industrial quality control. Professionals seeking to implement high-speed, high-accuracy 3D measurement systems will find particular value in the practical calibration methods and system optimization techniques.
