1. A compact scanner, comprising:

  • (a) a waveguide that conveys light between a proximal and a distal end, said waveguide having an effective light source position proximate to the distal end;

    (b) an optical component that is attached to the distal end of the waveguide, said optical component reducing a numerical aperture of the lensed waveguide; and

    (c) an actuator for exciting a portion of the waveguide that is adjacent to the distal end and is cantilevered from the actuator to vibrate at a desired frequency and in a desired pattern, excitation of the portion of the waveguide that is cantilevered from the actuator causing a rotation to occur for scanning a region with light from the optical component.
