A new generation of sensors can be engineered based on the sensing of several markers to
satisfy the conditions of the multimodal detection principle. From this point of view …

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 this paper, a self-consistent inverse procedure is developed for the estimation of linear
thermal expansion coefficient and thermal diffusivity of solids from transmission …

The photoacoustic method with piezoelectric detection for the simultaneous evaluation of the
thermophysical properties is proposed. The approach is based on the settling of an …

In this paper, a simple multilayer perceptron neural network with forward signal propagation
was designed and used to simultaneously determine the main physical parameters, such as …

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 …

In this work was used infrared imagery to estimate thermal properties of solid materials. The
Two Superficial Hot Points Technique (TSHP) was proposed and it uses heat flux and …

In this work, theoretically/mathematically simulated models are derived for the photoacoustic
(PA) frequency response of both volume and surface optically-absorbing samples in a …

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 engineering application, analyzing the temperature field of structures is often necessary.
The contact surface is constituted by the superposition of different scales of rough surfaces …
