Thermal and mechanical piston influence on photoacoustic signal
Abstract
In this work, the influence of the thermal and mechanical piston effects over the frequency at which the amplitudes of the components of the photoacoustic signal resulting from these two effects are equalized. The analysis was done in the measuring range 10 to 20kHz. An aluminum sample illuminated with modulated light, whose thickness varies from 10 to 1000 microns, was considered. It is important for development reliable inverse procedures and determination various properties of samples from experimental measurement.
