Record 1 2012-05-16

English

Subject field(s)
  • Medical Instruments and Devices
  • Ultrasonography
  • Cardiovascular System
CONT

Blood Velocity Meter. A continuous ultrasonic wave in the megahertz region is scattered as it passes through blood. The back-scattered part of the signal can be collected by a receiving transducer next to the transducer emitting the continuous waves, and the returning signal will be shifted in frequency in proportion to the velocity of the blood in the vessel. This Doppler frequency shift can be detected and applied to a frequency meter(e. g. zero crossing detector) or frequency analyzer to produce a signal proportional to blood velocity.

Key term(s)
  • blood-velocity meter

French

Record 8 1979-03-21

English

Subject field(s)
  • Scientific Instruments
  • Scientific Measurements and Analyses
  • Radio Waves
OBS

Microwave: An electromagnetic wave which has a wavelength between about 0.3 and 30 centimeters, corresponding to frequencies of 1-100 gigahertz; however, there are no sharp boundaries distinguishing microwaves from infrared and radio waves.

OBS

Spectrum analyzer. A device which sweeps over a portion of the radio-frequency spectrum, responds to signals whose frequencies lie within the swept band, and displays them in relative magnitude and frequency on a cathode-ray-tube screen. In essence, it is a superheterodyne receiver having a local oscillator whose frequency is varied cyclically, usually at the power-line frequency.

French

Domaine(s)
  • Instruments scientifiques
  • Mesures et analyse (Sciences)
  • Ondes radioélectriques
OBS

Analyse de spectres hyperfréquences. (...) Les analyseurs de spectres donnent directement une vue panoramique de l'amplitude en fonction de la fréquence sur l'écran d'un oscillographe. (...) Principe des analyseurs. (...) l'appareil (...) est essentiellement un récepteur superhétérodyne à bande passante très étroite. Ce récepteur explore automatiquement une bande de fréquences donnée grâce à un balayage linéaire, en dents de scie, de l'oscillateur local, synchronisé avec celui de l'oscilloscope.

OBS

Hyperfréquences. Ce terme désigne le domaine de fréquences des ondes électromagnétiques situé entre un gigahertz (...) et quelques centaines de gigahertz (...)
