Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-53: Examinations and measurements - Encircled angular flux (EAF) measurement method based on two-dimensional far field data from step index multimode waveguide (including fibre)
IEC 61300-3-53:2015(E) is intended to characterize the encircled angular flux of measurement step index multimode waveguide light sources, in which most of the transverse modes are excited. The term waveguide is understood to include both channel waveguides and optical fibres but not slab waveguides in this standard. Encircled angular flux (EAF) is the fraction of the total optical power radiating from a step index multimode waveguide's core within a certain solid angle. The EAF is measured as a function of the numerical aperture full angle. The basic approach is to collect, for every measurement, two dimensional far field data using a calibrated camera and to convert them mathematically into encircled angular flux. Keywords: encircled angular flux (EAF), measurement step index multimode waveguide light sources

IEC 61300-3-53:2015 cette publication est destinée à caractériser le flux angulaire inscrit lors de mesures portant sur des sources de rayonnement lumineux dotées d’un guide d’ondes multimodal à saut d’indice, où la plupart des modes transversaux sont excités. Dans la présente norme, le terme « guide d’ondes » est à considérer comme incluant à la fois des guides d’ondes de canal et des fibres optiques, mais pas les guides d’ondes rectangulaires rigides. Le flux angulaire inscrit (EAF) est la fraction de la puissance optique totale rayonnée par le cœur d’un guide d’ondes multimodal à saut d’indice dans un certain angle solide. L’EAF est mesuré en fonction de l’angle d’ouverture numérique complet. L’approche fondamentale consiste à recueillir pour chaque mesure des données bidimensionnelles de champ lointain en utilisant une caméra étalonnée et à les convertir mathématiquement en flux angulaire inscrit. Mots clés: flux angulaire inscrit (EAF). mesures portant sur des sources de rayonnement lumineux dotées d’un guide d’ondes multimodal
Optični spojni elementi in pasivne komponente - Osnovni preskusni in merilni postopki - 3-53. del: Preiskave in meritve - Merilna metoda obdanega koničastega pretoka (EAF), osnovana na dvodimenzionalnih podatkih daljnega polja iz večrodovnega valovoda (vključno z optičnim vlaknom) s stopničastim lomnim likom (IEC 61300-3-53:2015)
Ta del standarda IEC 61300 je namenjen opredelitvi obdanega koničastega pretoka svetlobnih virov večrodovnega valovoda s stopničastim lomnim likom, v katerem je vzbujena večina transverzalnih rodnih tipov. Izraz valovod zajema kanalske valovode in optična vlakna, ne pa tudi ploščatih valovodov v tem standardu.
Obdani koničasti pretok (EAF) je delež skupne optične moči, ki seva iz sredice večrodovnega valovoda s stopničastim lomnim likom v določenem prostorskem kotu. Obdani koničasti pretok se meri kot funkcija celotnega kota numerične aperture. Osnovni pristop temelji na zbiranju dvodimenzionalnih podatkov daljnega polja pri vsakem merjenju z umerjeno kamero ter njihovi matematični pretvorbi v obdani koničasti pretok.
