The dynamics of volcanic eruption columns involve the two-phase interaction of hot fragmented ash and pumice with volcanic gases and entrained air. There has been a very substantial literature about ...

Researchers have developed a new type of lidar system that can do much more than traditional versions. In a single ...

Researchers have developed a new kind of lidar system that simultaneously measures the location, speed and material ...

Researchers have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum of the light by ...

In an attempt to speed up quantum measurements, a new Physical Review Letters study proposes a space-time trade-off scheme that could be highly beneficial for quantum ...

With the Speetec, Sick is expanding its product range for speed and length measurement of objects moving in a linear path to include technology that measures directly on the material surface. The ...

Measuring the velocity field of a fluid flow, such as air or water, allows for greater feedback and control, something that could boost the performance and fuel-efficiency of aircraft. A research ...

Researchers have developed a faster and more accurate method for acquiring and reconstructing high-quality 3D surface measurements. The approach could greatly improve the speed and accuracy of surface ...

On one hand, the speed of light is just a number: 299,792,458 meters per second. And on the other, it’s one of the most important constants that appears in nature and defines the relationship of ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

A research group has developed, and now successfully tested, a new method to measure fluid flow velocities. Sparse processing particle image velocimetry (SPPIV) optimizes conventional measurement ways ...

Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the colour of a pulsed laser, the team can ...
