Laser vibrometry is used for research and diagnostics on the inner and middle ear. Vibrometers have also been used for measuring vibration on artificial heart valves to analyze vibrations during ...

DIFFERENTIAL Doppler measurements on radio waves emitted from artificial satellites have been successfully used to obtain data of the ionospheric electron content. Uncertainties inherent in the ...

Doppler ultrasound blends physics and medical imaging to reveal the movement of blood through vessels and the heart. From diagnosing clots to assessing heart valve function, it’s a non-invasive tool ...

Analog Devices has released the AD8333, which it claims is the first dual-channel I/Q (in-phase and quadrature) demodulator and phase-shifter for CW (continuous wave) Doppler ultrasound applications.

Radar is quite spectacular in telling us exactly where rain is falling by pinging precipitation with radio waves! Our weather radar can determine more than just a storm’s location, but its movement as ...

The Doppler Effect is physics that is so ingrained in our brain that even the movies get it right. Any time some character is walking down a street and a car or train rushes past, the sound of the ...

On today’s episode of “For Science!” we invite a very special guest to the lab, 9 & 10 chief meteorologist Michael Stevens to discuss the often misunderstood concept of Doppler. Many believe that the ...

The purpose of a Doppler ultrasound is to check blood flow. Doctors use the findings to help determine whether there is a blockage, narrowing, or leakage in a blood vessel. Healthcare professionals ...
