1. Apparatus for mapping, comprising:

  • an illumination module, comprising;

    a radiation source, which is configured to emit a beam of radiation;

    a scanner, which is configured to receive and scan the beam over a selected angular range; and

    illumination optics, which are configured to project the scanned beam so as to create a pattern of spots extending over a region of interest;

    an imaging module, which is configured to capture an image of the pattern that is projected onto an object in the region of interest; and

    a processor, which is configured to process the image in order to construct a three-dimensional (3D) map of the object.
