C. Glorieux et al., Depth profiling of thermally inhomogeneous materials by neural network recognition of photothermal time domain data, J APPL PHYS, 85(10), 1999, pp. 7059-7063
Thermal conductivity depth profiles of thermally inhomogeneous materials ar
e retrieved from the time dependence of the surface temperature after a fla
sh illumination. A neural network method, which is trained to recognize the
correlation between depth profiles and the surface temperature on the basi
s of many examples, is employed. Depth profiles retrieved from simulated no
isy signals are shown and the average reconstruction errors are analyzed fo
r different circumstances. (C) 1999 American Institute of Physics. [S0021-8
