Abstract:
A concise description of models of a PA signal formation is presented, which can be used in determination of the vibrational relaxation time. A three-dimensional model of PA signal generation that describes the gas pressure onto a microphone membrane, located at the center of a side wall of a cylindrical cell, at pulsed excitation of the gas with allowance for diffusion of molecules from the illuminated volume, is proposed.
