Pulse Shapes Techniques Application to Intense Pulsed Light for skin lesions
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 6
Abstract
Intense pulsed light causes changes in the blood vessels inside the corium after passing through the skin. In addition, it affects fibroblasts, imparts elasticity to skin collagen and induces filling of the skin epidermis. According to several diagnostic purposes, a method for controlling the operating time due to the output pulse can be applied by changing the control pulse. Various output pulses are needed for different treatment methods of Intense Pulsed Light(IPL) in accordance with the skin color and lesion. Since the heating pulse intensity, pulse width and pulse shape need to be tailored to the skin condition, there is some restriction in terms of the range of treatments as well as the diagnosis with the existing pulse techniques. A population inversion was induced by heat pumping a Xe Lamp through a Variable Pulse Beam Shapes. The necessary discharge energy was charged through the network to produce various current pulses. By grafting a one chip Microprocessor and Variable Pulse Beam Shapes of an AVR affiliation, a circuit was designated from the 1st to 8th levels. Xenon gas was used as the medium. The output, pulse width and pulse count was 15J/㎠～45J/㎠, 0.5ms～15ms, and 1 ㎐～3 ㎐, respectively. As a result, the corresponding current waveform could be recognized through a PSPICE simulation and the experimentally determined waveform. Moreover, both the efficiency and maximum output changed according to the results of the Discharging Light of Variable Pulse Beam Shapes.
