42Transcranial doppler — (TCD) is a test that measures the velocity of blood flow through the brain s blood vessels. Used to help in the diagnosis of emboli, stenosis, vasospasm from a subarachnoid hemorrhage (bleeding from a ruptured aneurysm), and other problems, this… …
43Laser 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… …
44Transverse 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… …
45Lamb shift — In physics, the Lamb shift, named after Willis Lamb (1913 2008), is a small difference in energy between two energy levels ^2S {1/2} and ^2P {1/2} of the hydrogen atom in quantum mechanics. According to Dirac and Schrödinger theory, hydrogen… …
46Bistatic Doppler shift — is a specific example of the Doppler effect that is observed by a radar or sonar system with a separated transmitter and receiver. The Doppler shift is due to the component of motion of the object in the direction of the transmitter, plus the… …

49Blue shift — is the shortening of a transmitted signal s wavelength, and/or an increase in its frequency, due to the Doppler Effect, which indicates that the object is moving toward the observer. The name comes from the fact that the shorter wavelength end of …
50Bathochromic shift — is a change of spectral band position in the absorption, reflectance, transmittance, or emission spectrum of a molecule to a longer wavelength (lower frequency).This can occur because of a change in environmental conditions: for example, a change …
