A hammer impact must be repeated for each scan point to measure points consecutively with a Polytec Scanning Laser Vibrometer. As a result, automated modal hammers such as the SAM, developed by ...

Researchers have introduced an innovative two-step excitation approach that makes it possible to efficiently generate and clearly separate different modes of hyperbolic polaritons. An international co ...

SRL has a linear relation to the molecular concentration and the Raman cross section, and it can be detected by classical heterodyne detection method to achieve the same shot-noise-limited sensitivity ...

A new two-step excitation technique efficiently generates and separates different modes of hyperbolic polaritons - directional nanoscale light-matter modes with extreme electromagnetic field ...

SAE Transactions, Vol. 110, Section 6: JOURNAL OF PASSENGER CAR: MECHANICAL SYSTEMS JOURNAL (2001), pp. 1944-1948 (5 pages) In order to engineer Squeak & Rattle (S&R) free vehicles it is essential to ...

Laser shearography as a nondestructive testing (NDT) method has been used in a production environment for composite structures for two decades and on a variety of aircraft, including the F-22 stealth ...

"18-Weldt" project develops method to inspect welds in difficult-to-access industrial parts. A novel thermographic method for automatic inspection of welds in hard-to-reach areas has been developed In ...

Although the composites industry was still in its infancy in the late 1960s, it was among the earliest to recognize thermography’s potential in nondestructive testing (NDT), when the first commercial ...

Stimulated Raman Scattering (SRS) has been developed as an essential quantitative contrast for chemical imaging in recent years. However, the spectral resolution of the mainstream SRS modalities is ...

Illustration of nanolight pseudo-birefringence. Two-step excitation via a light-illuminated antenna and a sharp boundary efficiently excites higher-order light-matter waves (hyperbolic phonon ...
