 Context examples 

The method used for detection of planets is known as the Doppler technique.

(Researchers find two new planets with masses similar to Earth’s near a small neighbouring star, University of Granada)

A technique that combines laser Doppler velocimetry and phase analysis light scattering to determine the zeta potential of a sample.

(Laser Doppler Velocimetry-Phase Analysis Light Scattering, NCI Thesaurus)

An instrument that can perform laser Doppler velocimetry and phase analysis light scattering to determine the zeta potential of a sample.

(Laser Doppler Velocimetry-Phase Analysis Light Scattering System, NCI Thesaurus)

A classic Doppler effect example is how the pitch of a police siren drops once it passes.

Subtle changes in the wavelength of this light due to the Doppler effect reveal the motions of the gas in the disc.

(ALMA Discovers Trio of Infant Planets around Newborn Star, ESO)

Because of the Doppler Effect, this means that different slices of the data cube show images of gas moving at different speeds towards or away from the observer.

(Ageing Star Blows Off Smoky Bubble, ESO)

Diagnostic imaging that uses sound waves (ultrasound) applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow.

(Doppler Ultrasound, NCI Thesaurus)

The SJSU researchers mounted Doppler LiDAR (Light Detection and Ranging, a remote-sensing method that uses light in the form of a pulsed laser to measure distances) instruments onto a pickup truck, which they placed near wildfires.

(Researchers discover how wildfires create their own weather, National Science Foundation)

The researchers used the Doppler effect to measure these lines and observe the velocity of gas feeding into the disk, toward the black hole.

(Astronomers Study How Quasars Are Powered by Accretion Disks, The Titi Tudorancea Bulletin)

This shift creates a very subtle Doppler effect in the light dispersed by stars, which, by using CARMENES, can be measured with an accuracy of 1 metre per second—equivalent to walking speed, or, 3.6km per hour.
