Abstract
A photonic scanning and delivery system capable of controllable transmission of light energy to an irregularly shaped treatment area are disclosed. The desired uniformity (controllability) of light energy application is ensured by a tracking device, which monitors the position of the radiation applicator and thereby prevents over- or under-radiation. The system employs a light energy delivery hand-piece. By these means, structures in the lower dermis are irradiated. Because of the large size of the treatment area, damage to surface tissue is avoided. The hand-piece can operate while in contact with the treatment surface. Treatment surfaces include non-medical work sites. Alternatively, the hand-piece can operate in a non-contact mode. The system can also be used in non-medical applications such as UV curing.
