Voids, the most studied type of manufacturing defects, form very often in processing of fiber-
reinforced composites. Due to their considerable influence on physical and …

Originally developed for diagnostic ultrasound imaging, piezoelectric transducers are the
most widespread technology employed in optoacoustic (photoacoustic) signal detection …

Objective: Photoacoustic (PA) imaging emerges as a unique tool to study biological samples
based on optical absorption contrast. In PA imaging, piezoelectric transducers are …

Abstract The Synthetic Aperture Focusing Technique (SAFT) is an imaging algorithm used in
laser ultrasonics (LU) to visualise the appearance of defects. However, ultrasound excited …

In this article, we present an overview of recent progress in non-contact remote optical
detection of ultrasound in application to nondestructive testing and evaluation of materials …

Impact damage of laminated composite structures continues to be a challenging problem.
The complexity of damage morphology, the sequence of damage events, and multiple …

Inspection of adhesively bonded metallic plates, commonly used in aircraft structures,
remains challenging for modern non-destructive testing (NDT) techniques. When a probing …

Damage induced in polymer composites by various impacts must be evaluated to predict a
component's post-impact strength and residual lifetime, especially when impacts occur in …

Adhesively bonded metals are increasingly used in many industries. Inspecting these parts
remains challenging for modern non-destructive testing techniques. Laser ultrasound (LU) …

Numerous nondestructive testing (NDT) methods have been developed to perform
inspections of engineered structures. Frequently, increased precision of a given method is …
