“…A espectrofotometria fotoacústica (ou optoacústica) explora a expansão térmica da amostra irradiada e pode ser aplicada a gases, sólidos e líquidos. Descrições detalhadas dos conceitos, instrumentação e aplicações destas técnicas podem ser encontradas em artigos de revisão [73][74][75] .…”

“…The harnessing of the photoacoustic effect for gathering spectroscopic (photoacoustic spectroscopy (PAS)) and spectrometric (thermal-wave imaging, thermal diffusivity) information from opaque and light-scattering materials is established and well documented (1,2). By exploiting the relationship between thermal-diffusion length in samples and source-modulation frequency, one can obtain depth-related information about the distribution of chromophores (2)(3)(4).…”

“…The autocorrelation function R, (see [I]) yields the degree of correlation for a single variable ( fl(t)), while the cross-correlation function R, (see [2]) describes the similarity between two variables (f (t) and f2(t)).…”
