    Abstract: Disclosed is an optical coherence tomography scanner and a method for recording sub-surface scans of an object, wherein a position encoder is arranged in the path of the probing beam of an interferometric system. The encoder pattern is detected in a sequence of A scans at generated for different probing beam positions on the scanned object, the probing beam position and/or inclination for at least one A scan of said sequence of A scans is deducing based on the detected encoder pattern, and the sub-surface scan of the object is generated based on the sequence of A scans taking into account the deduced probing beam position and/or inclination.

    Abstract: Disclosed is a structured light 3D scanner based on the principle of triangulation with a light source for generating a light pattern, two cameras with two-dimensional sensors recording the reflection of the light pattern from a target object, and one axis moving the cameras. Wherein the cameras are arranged with at least partly overlapping fields of view and where the sensors in the cameras are read out partially and concurrently during at least some period of the scanning process, thus providing partial images and where the partial images are merged prior to performing the triangulation calculations.
