1. A device for three-dimensional imaging, the device comprising:

  • a structured light illuminator having one or more movable illuminator lenses positioned proximate an output of the illuminator, the one or more movable illuminator lenses configured to vary a field of illumination of the illuminator; and

    an imaging sensor having one or more movable imaging lenses positioned proximate an input of the imaging sensor, the one or more movable imaging lenses configured to vary a field of view of the imaging sensor, the field of view of the imaging sensor and the field of illumination of the illuminator being linked, such that the field of view of the imaging sensor is the same as the field of illumination of the illuminator at a short throw field of view and a long throw field of view.
