Abstract
A method comprises a) radiating at least one measurement light pulse having a pulse duration and intensity onto a measurement area of the inhomogeneous sample; b) detecting at least one pressure transient at the measurement area; and c) calculating a value for the energy density absorbed by the sample during the pulse duration from a curve of the at least one pressure transient at the start and at the end of the at least one measurement light pulse. The method further includes: repeating steps a) to c) for different angles of incidence of the measurement light; modelling the inhomogeneous sample as a stack of layers, each layer being assigned at least a layer thickness and an absorption coefficient, at least one absorption coefficient of a layer being a fitting parameter; and performing a fitting procedure for the fitting parameters; outputting the fitted fitting parameters.
