Paper Abstract

In this paper, for an inhomogeneous material in which the thermal conductivity is varied as a function of depth, we propose an efficient method to inversely compute the depth distribution of optical-absorption coefficient by the surface temperature of the material. The results of inverse computation by a group of surface temperature data show that some more accurate optical- absorption coefficients can be obtained.
