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 ...

This paper describes a new method of measuring the absolute speed of moving objects such as people who are walking or running, running animals, vehicles, sailing boats and the like. The method ...

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 ...

While today's law enforcement officers don't wear utility belts full of crimefighting gadgets like Batman, they do rely on a variety of state-of-the-art technologies to do their jobs efficiently and ...

Scientists have demonstrated the fastest distance measurement so far. The researchers demonstrated on-the-fly sampling of a gun bullet profile with micrometer accuracy. The experiment relied on a ...
