摘要：
A hand-held device for providing a dermatological treatment by scanning a laser beam to form a pattern of treatment spots on the skin includes a laser source that generates an input 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 beam, each scan providing an array of output beams corresponding to the multiple sectors of the scanning element and forming a scanned row of treatment spots on the skin. The scanning element is configured such that each sector provides a constant-angular-direction output beam as that sector rotates through the input 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 provides a distance between adjacent rows of treatment spots in a direction of manual movement of the device.
