Intense Pulsed Light systems employ flash lamps as optical sources to provide the required light intensity with certain temporal profile for use in a large number of medical applications; namely, the aesthetic ones. Driving a flash lamp requires high voltage DC power supply, capacitive energy storage, and flash lamp triggering unit. Single and double-mesh discharge and triggering circuits were designed and built to provide intense light pulses of variable time durations. Variable energy and duration intense light pulses needed in aesthetic medical applications were obtained. The system was treated as circuit with a light pulse profile follows the temporal behavior of the exciting current pulse. Distributing the energy delivered to one lamp on to a number of LC meshes permitted longer current pulses, and consequently, increased the light pulse length and shortened its current rise time.
Driving a flash lamp in an intense pulsed light system requires a high-voltage DC power supply, capacitive energy storage and a flash lamp triggering unit. Single, double, triple and quadruple-mesh discharge and triggering circuits were constructed to provide intense light pulses of variable energy and time durations. The system was treated as [Formula: see text] circuit in some cases and [Formula: see text] circuit in others with a light pulse profile following the temporal behaviour of the exciting current pulse. Distributing the energy delivered to one lamp onto a number of LC meshes permitted longer current pulses, and consequently increased the light pulse length. Positive results were obtained when using the system to treat skin wrinkles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
