The common functional brain imaging modalities, including functional magnetic resonance imaging (fMRI) and positron emission tomography, have excellent depth penetration but do not provide good ...

WEST LAFAYETTE, Ind. — Doppler radar improves lives by peeking inside air masses to predict the weather. A Purdue University team is using similar technology to look inside living cells, introducing a ...

Though Doppler seems relatively simple to implement in ultrasound, analog performance in the latest systems has much higher, more-difficult-to-achieve specifications than standard black-and-white ...

You must have noticed the sudden change in pitch of a siren on a police car zooming past. That’s the Doppler effect. Scientists at Purdue University have now used the Doppler effect to look inside ...

For years now, we’ve though of Augmented Reality in the context of our vision — Google Glass started the trend, and the Microsoft HoloLens enforced it. But the folks at Doppler Labs believe the future ...

New measuring methods of diesel spray characteristics were investigated by using laser Doppler signals, when diesel spray was injected into a high pressure vessel at ...

The Indus Doppler Flow Velocity System is a high-frequency, real-time pulsed Doppler measurement tool with built-in data processing software intended to assess small animals' cardiovascular health.

A novel method using signals of opportunity from Low Earth Orbit (LEO) satellites is redefining what’s possible in satellite-based navigation. Researchers have developed a joint pseudo-range and ...
