Beschreibung:
This book begins by establishing the theoretical foundations of fringe pattern analysis, reviewing various 3D imaging techniques while highlighting the advantages of digital fringe projection. The author then describes the differences between digital light processing, liquid crystal display, and liquid crystal on silicon. He explains how to unwrap phase maps temporally and spatially, how to generate fringe patterns with video projectors, and how to convert phase to coordinates through system calibrations. A detailed example of a built-from-scratch 3D imaging system are provided.
