Infrared thermography as contactless method for determining the temperature distribution on the surface is used for analyzing the impact of intense pulsed light hair removal device (IPL) on the skin. Depth of light penetration depending of wavelength is described as well as absorption curves and IPL impulse shapes. Energy balance and IPL impulse influence on the skin is analyzed. Melanin temperature rise by different fluence operation and temperature distribution in the modeled hair is used in order to determine overall skin temperature rise. Estimated energy balance provided by mathematical model has been confirmed with experimental results. Performed measurements, beside determination of the right emissivity, required the identification of most significant parameter in the process which proved to be the skin reference temperature and real temperature rise. Practical IPL application with detailed body temperature analysis is comprehensively described and thermal imaging interpretation problem and determination of the temperature rise is observed.
红外热成像作为一种用于确定表面温度分布的非接触式方法，被用于分析强脉冲光脱毛设备（IPL）对皮肤的影响。文中描述了光穿透深度与波长的关系、吸收曲线以及IPL脉冲形状。分析了能量平衡和IPL脉冲对皮肤的影响。通过不同能量密度操作下黑色素的温度升高以及模拟毛发中的温度分布，来确定皮肤的整体温度升高。数学模型提供的估计能量平衡已得到实验结果的证实。所进行的测量，除了确定正确的发射率外，还需要识别该过程中最重要的参数，事实证明该参数是皮肤参考温度和实际温度升高。文中全面描述了具有详细体温分析的实际IPL应用，并观察了热成像解释问题和温度升高的确定。
