    Abstract: Apparatus (20) for mapping includes an illumination module (30), which includes a radiation source (32), which is configured to emit a beam of radiation. A scanner (34) receives and scans the beam over a selected angular range. Illumination optics (35) project the scanned beam so as to create a pattern of spots extending over a region of interest. An imaging module (38) captures an image of the pattern that is projected onto an object (28) in the region of interest. A processor (46) processes the image in order to construct a three-dimensional (3D) map of the object.
