Abstract
A hand-held device for providing a dermatological treatment by scanning laser beams to form a pattern of treatment spots on the skin includes a laser source configured to generate an input laser beam, an automated scanning system, and a treatment spot control system. The automated scanning system includes a rotating multi-sector scanning element configured to repeatedly scan the input laser beam, each scan of the input laser beam providing an array of output laser beams corresponding to the multiple sectors of the scanning element and forming a scanned row of treatment spots on the skin. The rotating multi-sector scanning element is configured such that the each sector provides a constant-angular-direction output laser beam as that sector rotates through the input laser beam. The treatment spots of each scanned row are spaced apart from each other by areas of non-irradiated skin. The treatment spot control system is programmed to provide a defined minimum distance between adjacent rows of treatment spots in a direction of manual movement of the device.
