Abstract
A scanning optical system for delivering electromagnetic radiation onto tissue to be treated is cooperative with a lightguide or optical fiber. Radiation to be delivered is provided by a source thereof via the optical fiber. The optical system includes an optical projection arrangement comprising a plurality of lenses cooperatively arranged with the lightguide. A first of the lenses is arranged to receive radiation emerging from the lightguide. The beam of radiation is passed through the projection arrangement to form a treatment spot the radiation on the tissue. Scanning is effected by causing relative motion between the exit-end of said lightguide and at least the first lens, transverse to the optical axis of the projection arrangement. The treatment spot undergoes a related transverse motion over the tissue. In one example scanning is effected by moving the first lens with the lightguide fixed. The first lens is moved using an arrangement of piezo-electric actuators.
