Abstract

A technique for computer retrieval of the pressure signal form from a pulse microphone signal is proposed. It is shown that the time of collisional relaxation of molecules from the excited state to the ground state can be measured on the basis of this technique with the use of a time-resolved photoacoustic spectrometer.
