Abstract
An apparatus is provided for 3D imaging of an object comprising a scanning light beam encoded with position data corresponding to the spatial position of the scanning light beam, and an imaging system that images localized surface areas of the object illuminated by the scanning light beam, which imaging system records the position data coded into the scanning beam so that three spatial coordinates of the localized surface areas imaged are determinable using the recorded position data.
