ABSTRACT
Presents a pulsed photoacoustic spectroscopy (PAS) technique for immediate measuring absolute optical absorption coefficient. Use of amplitude-time characteristics of photoacoustic (PA) signal generated in air surrounding the sample under investigation as basis of the technique; Derivation of the time dependence of PA signal for each PA cell chamber.
