<p>A compact, hand-held device is provided for providing radiation-based dermatological treatments, e.g., skin resurfacing, skin rejuvenation, wrinkle treatment, pigmentation removal or reduction, hair removal, acne treatment, skin tightening, etc. The device may include one or more radiation sources (e.g., one or more lasers) and an automated scanning system for delivering an array of scanned beams to the skin, while the device is manually moved across the skin, to produce an ar¬ ray of discrete treatment spots on the skin, e.g., to provide a fraction¬ al treatment. The automated scanning system may include a rotating multi-sector scanning element configured to repeatedly scan an input beam, with each scan of the input beam 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.</p> |
