Abstract: A device includes an optical scanner that comprises a mirror, a first actuator that rotates the mirror around a first axis of rotation, a first angular position sensor that senses an angular position of the mirror around the first axis of rotation, a second actuator that rotates the mirror around a second axis of rotation, a second angular position sensor that senses an angular position of the mirror around the second axis of rotation, and a controller coupled to the first and second drivers to drive the respective first and second actuators to rotate the mirror into respective angles around the first and second axes of rotation.

Abstract: A handpiece for treatment of the surface of a target tissue with at least one light beam is provided, the handpiece including a housing, at least one light source for generating at least one light beam, an opening for allowing the emission of the at least one light beam out of the housing and towards the target surface, a mechanism for controlled displacement of the at least one light source to move the at least one light beam across the target surface; and a controller for controlling the mechanism. A method is provided for treating a tissue surface with a light beam that includes directing a light beam towards the tissue surface, focusing the light beam at the tissue surface so that the focal point is positioned proximate the surface of the tissue so that the diameter of the light beam is smaller at the surface of the tissue than below the surface.
