English

Subject field(s)
  • Optical Telecommunications
  • Photoelectricity and Electron Optics
CONT

The mode field diameter is a measure of the radial intensity distribution of radiation propagating within a fibre. It is a key parameter for the specification of single-mode fibre and can be used to predict fibre properties such as splice loss, microbending loss, cut-off wavelength and waveguide dispersion.

French

Domaine(s)
  • Télécommunications optiques
  • Photo-électricité et optique électronique
DEF

Dispersion causée par la variation des vitesses de phase et de groupe relativement à la longueur d'onde; cette dispersion est liée aux propriétés géométriques de la fibre optique.

OBS

Dans une fibre optique, la dispersion est provoquée par différents mécanismes : la dispersion de matériau, la dispersion de guidage et la dispersion de profil.

Record 2 2004-09-17

English

Subject field(s)
  • Measuring Instruments (Engineering)
CONT

The optical extensometer is a robust and extremely accurate fiber-optic displacement transducer. Its compact design allows it to measure a wide range of length changes and displacements of up to 5 mm. The optical extensometer registers these mechanical variables with a sensing head and converts them internally into optical signals. Conversion is performed in accordance with a patented microbending principle. The optical extensometer is able to register static and dynamic measurement variable over periods ranging from brief to many years, in accordance with the users requirements.

PHR

bi-axial, computer assisted, electro, fast scanning, recording, non-contacting, long-base, multipoint, 3D optical extensometer

French

Domaine(s)
  • Instruments de mesure (Ingénierie)
DEF

Capteur d'allongement à fibres optiques robuste et particulièrement précis qui capte les déformations à l'aide d'un palpeur et les convertit en un signal optique. Il est en mesure de saisir des valeurs tant statiques que dynamiques sur le court ou le long terme.

PHR

extensomètre optique infra-rouge, temps réel, 3D
