Abstract
A self-contained, hand-held device for providing a dermatological treatment includes a handheld device body, a radiation source supported in the device body, an automated scanning system, an application end, and a displacement control system. The automated scanning system is configured to receive an input beam generated by the radiation source and scan the received input beam to provide a series of output beams for delivery to the skin via the application end of the device to form a pattern of treatment spots on the skin. The application end is configured to be manually moved across the surface of the skin during a treatment session. The displacement control system includes a displacement sensor configured to determine a displacement of the device relative to the skin, and electronics configured to control at least one operational parameter of the device based on the determined displacement of the device relative to the skin.
