“…As an example, the study of the PA response near Vickers-indented areas in ceramics demonstrated the significant dependence of acoustic signals on internal and external stresses at the tips of near-surface cracks. The PA signal's formation inside Vickers indents in metals showed the same behavior in [54]. PA imaging close to the indented areas was obtained by scanning the sample's surface using the laser beam.…”

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, photoacoustic-based sensing approaches are essential. The photoacoustic effect relies on the generation of light-induced deformation (pressure) perturbations in media, which is essential for sensing applications since the photoacoustic response is formed due to a contrast in the optical, thermal, and acoustical properties. It is also particularly important to mention that photoacoustic light-based approaches are flexible enough for the measurement of thermal/elastic parameters. Moreover, the photoacoustic approach can be used for imaging and visualization in material research and biomedical applications. The advantages of photoacoustic devices are their compact sizes and the possibility of on-site measurements, enabling the online monitoring of material parameters. The latter has significance for the development of various sensing applications, including biomedical ones, such as monitoring of the biodistribution of biomolecules. To extend sensing abilities and to find reliable measurement conditions, one needs to clearly understand all the phenomena taking place during energy transformation during photoacoustic signal formation. Therefore, the current paper is devoted to an overview of the main measurement principles used in the photoacoustic setup configurations, with a special focus on the key physical parameters.

“…Для металлов же детального экспериментального и теоретического исследования поведения ФА-сигналов в металлических образцах в условиях с хорошо известным характером распределения напряжений до настоящего времени не проводилось. В работах [9][10][11] было экспериментально показано, что внут-ренние и внешние механические напряжения в металлах существенно влияют на характеристики ФА-сигналов в зонах индентации по Виккерсу. Однако сложность структуры отпечатков по Виккерсу не позволила оценить степень влияния напряжений в металлах на параметры ФА-сигналов.…”

Из теории образования лазерных ФА-сигналов по термоупругому механизму известно, что в квазистатическом приближении [9][10][11] величина сигнала определяется коэффициентом теплового расширения материала в зоне воздействия лазерного излучения и может быть представлена в виде…”

The nature of the change in the photoacoustic signal around the hole in samples of duralumin is studied. A com- parison of the experimental results with the solution of the classical problem for stress distribution around a circular hole in a prestressed plate is made. A good correspondence between the behavior of the photoacoustic signal with piezoelectric recording and the distribution of stresses around the hole is demonstrated. The possibility of estimating the internal stresses by the photoacoustic method in combination with the hole drilling method is shown.
