Abstract
The system includes an illumination system, a scanner, a non-linear optical element, and a pumping light source. The illumination system emits imaging beam and the scanner scans the beam incident from the illumination system. The non-linear optical element is made of a material having a Kerr effect or the like and forms a lens automatically aligned while following a path of the imaging beam scanned from the scanner. The pumping light source actives the non-linear optical element to cause a non-linear refractive index change of the non-linear optical element.

An optical scanning imaging system comprising:
- an illumination system emitting an imaging beam;
- a scanner scanning the beam incident from the illumination system;
- a non-linear optical element made of a material having a Kerr effect and forming a lens automatically aligned while following a path of the imaging beam scanned by the scanner;
- and
- a pumping light source causing non-linear optical refractive index change that forms the lens in the non-linear optical element while following the path of the imaging beam by activating the non-linear optical element.
