Nondestructive testing (NDT) of historic structures can be used for architectural archaeology, structural stability analysis, or materials characterization. Four types of physical probes are available: sound, penetrating radiation, visible light, and electromagnetism. Each of these can be utilized in several ways. Additional options involve hybrid techniques that combine probe methods. Widespre...

Radiation damage is considered to be the major problem that still prevents imaging an individual biological molecule for structural analysis. So far, all known mapping techniques using sufficient short wavelength radiation, be it x rays or high energy electrons, circumvent this problem by averaging over many molecules. Averaging, however, leaves conformational details uncovered. Even the antici...

With the electronic industry being one of the most dynamic, in terms of new technologies, electronic packages have to be designed and optimized for new and ever more demanding applications in relatively short periods of time. This, in turn, indicates a need for effective quantitative testing methodologies. In this paper, a novel hybridized use of nondestructive, noninvasive, remote, full field ...

In this article, the state-of-the-art multi-wave and hybrid imaging techniques in the field of nondestructive evaluation and structural health monitoring were comprehensively reviewed. A new direction for assessment and health monitoring of various structures by capitalizing the advantages of those imaging methods was discussed. Although sharing similar system configurations, the imaging physic...

This paper presents design, construction and control of a quadruped robot, capable to maneuver on vertical surfaces. A nondestructive system integrated with the robot enables location and tracking of rebars in concrete structures. This paper illustrates robot manipulation in the kinematic approach and practical application of the platform dedicated for nondestructive testing. Streszczenie. W ar...

In the modern motorcar production, more than 300 deep-drawn sheet metal parts are joined together by more than 3,000 spot welds on each car body. To check the spot welds within the framework of the quality assurance, different nondestructive test methods are available in addition to the destructive methods (tear down test, metallographic inspection): the chipping test and the ultrasonic test, w...

Nondestructive quantum measurements are central for physics applications ranging from sensing to computing and communication. Employing the toolbox of cavity electrodynamics, we here concatenate two identical nondestructive photon detectors repeatedly detect track a single propagating through $60\,\mathrm{m}$ long optical fiber. By demonstrating that combined signal-to-noise ratio surpasses eac...

There is an ancient saying that "A picture is worth a thousand words". Never is this more true than when applied to nondestructive characterization of materials. It is also true that it was the very first nondestructive test. After God created the universe, he stopped and "saw that it was good". Visual inspection is still the nondestructive testing technique most often used in practical applica...

The extreme operational environmental conditions and aging of subsea structures pose a risk to their structural integrity is critical safety. Nondestructive testing essential identify defects developing within the structure, allowing repair in timely manner mitigate against failures that cause damage environment hazard human operators. However, be cost effective, inspections must carried out wi...
