Response of piezoelectric transducers used in pulsed optoacoustic spectroscopy.
A general scaling relationship is derived for detector sensitivity in terms of the acoustic properties of the absorber, permitting the transfer of calibration among different materials. A limiting case of an exciting optical-pulse duration's being short compared with acoustic relaxation time is considered in detail. A strong temperature dependence of the detector response is predicted for several materials of technical interest.
