    Notes: An analytical solution for the photothermally measurable surface temperature of a sample with piecewise linearly inhomogeneous depth profile of the thermal conductivity k is presented. Based on this solution an inversion algorithm using a sequence of one-parameter fits is suggested in order to estimate the k profile. Numerical simulations demonstrate the performance of the approach and its insensitivity to random errors. © 1995 American Institute of Physics.

    Notes: Surface problems in photothermal depth profiling of technical surfaces arise from the intrinsic optical absorptivity; therefore, it is not appropriate to use amplitude values for profile reconstruction. We report a reconstruction technique based only on phase data. The performance of this approach was tested successfully by measuring the thermal conductivity profiles of laser hardened steel samples. © 1996 American Institute of Physics.

    Notes: Experimental results of thermal conductivity depth profiling of case-hardened steel and mechanically loaded ceramics are presented, based on an inversion algorithm for a sample with piecewise linearly inhomogeneous depth profile of the thermal conductivity. The photothermally obtained profiles are interpreted or compared with results from conventional or destructive measuring techniques. © 1995 American Institute of Physics.
