多层不均匀材料中光吸收系数深度分布计算的理论处理

A Theoretical Treatment for Computation on Depth Distribution of Optical Absorption Coefficient in Multilayer Inhomogeneous Material

提出了一种通过光热法测定与样品表面温度有关的光热信号，重构反映多层不均匀材料中光吸收系数深度分布的理论处理和新的有效数值计算方法。数值模拟显示了较好的逼近效果。

A theoretical treatment and a new effective numerical method are proposed to reconstruct the depth distribution of optical absorption coefficient in multilayer inhomogeneous material by the optical and thermal signals, which are related to the surface temperature of the sample measured with the optical and thermal method. Numerical simulations demonstrate the performance of the approach is better.
