In this presentation, we provide a thorough overview of recent advances in 3D surface imaging technologies. We focus particularly on these non‐ contact 3D surface measurement techniques that require structured illumination. The high speed and high resolution pattern projection capability offered by the digital light projection (DLP) technology, together with the recent advent of imaging sensor technologies, may enable new generation systems for of 3D surface measurement applications that provide much better functionality and performance than existing ones, in terms of speed, accuracy, resolution, size, cost, and ease of use. Performance indexes of 3D imaging system in general are discussed and various 3D surface imaging schemes are categorized, illustrated, and compared. Numerous medical applications of 3D technologies are discussed with several examples.
