We present the temperature distribution predictions for photothermal systems by considering
an extension of dual-phase lag. It is an extension of the GCE-II and GCE-III models with a …

In order to make the photothermal effect detectable from a sample with low optical
absorption, an optically opaque layer must be applied on its surface. A model of optically …

The model of a photoacoustic gas-microphone signal in the time domain recorded in a
transmission configuration using a minimum volume cell is derived. This model takes into …

This paper analyzes the influence of the anomalous diffusive effects caused by micro-scale
heterogeneity and kinetic and inertial thermal relaxations on the optically induced …

The photoacoustic effect was explained more than half a century ago and has since been
used to develop non-destructive and non-contact techniques for testing materials. Most …

In this paper, the influence of the measurement range on the prediction of thermoelastic and
geometric properties of a thin aluminum sample obtained by solving the inverse …

Photoacoustic spectroscopy is a powerful, non-destructive, ultrasensitive technique that
covers a wide range of applications including atmospheric monitoring, industrial …

Photoacoustic spectroscopy achieves high sensitivity and selectivity using high-power
lasers. Variations of parameters such as laser beam spatial profile and fluence Φ can alter …

In this paper, the time-resolved model of the photoacoustic signal for samples with a
complex inner structure is derived including local non-equilibrium of structural elements with …

A development of simulated data and discussion on potential use in processing
photoacoustic measurement data, as well as in solving of an inverse problem are presented …
