Abstract
Cross-correlation photoacoustic spectroscopy (CPAS) of condensed matter carries spectroscopic information related to the optical absorption coefficient of solids in both signal magnitude and time delay channels. A one-dimensional theoretical model is presented in which the cross-correlation photoacoustic response to pseudo-random-binary-sequence (PRBS) optical excitation is evaluated for systems of variable optical absorption coefficients. The model is further compared to CPAS data from powders of Ho2O3 in the visible spectral range.Keywords
