2Doppler ultrasound — n ultrasound that utilizes the Doppler effect to measure movement or flow in the body and esp. blood flow called also Doppler ultrasonography * * * a diagnostic technique that utilizes the fact that the frequency of ultrasound waves changes when… …
3Doppler ultrasound — a diagnostic technique that utilizes the fact that the frequency of sound or light waves changes when they are reflected from a moving surface (the Doppler effect). It is used to study the flow in blood vessels and the movement of blood in the… …
4Doppler, Christian — ▪ Austrian physicist born Nov. 29, 1803, Salzburg, Austria died March 17, 1853, Venice Austrian physicist who first described how the observed frequency of light and sound waves is affected by the relative motion of the source and the… …
5Bat detector — The term bat detector is usually used to describe a device used to detect the presence of bats by converting their echolocation ultrasound signals to audible frequencies as they are emitted by the bats. There are other types of detector which… …
6Radar detector — A radar detector, sometimes called a fuzz buster, is a passive electronic device used by motorists to determine if their speed is being monitored by law enforcement agencies via a radar unit, and thereby, potentially avoiding prosecution for… …
7Laser Doppler Vibrometer — A Laser Doppler Vibrometer (LDV) is a scientific instrument that is used to make non contact vibration measurements of a surface. The laser beam from the LDV is directed at the surface of interest, and the vibration amplitude and frequency are… …

9Transverse Doppler effect — In special relativity, the transverse Doppler effect is the nominal redshift component associated with transverse (i.e. lateral) observation, and is important both theoretically and experimentally.OverviewIf the predictions of special relativity… …
10Laser Doppler velocimetry — (LDV, also known as laser Doppler anemometry, or LDA) is a technique for measuring the direction and speed of fluids (or any other material that is processed like metal, paper etc) like air and water. In its simplest form, LDV crosses two beams… …
