End-face image analysis procedure for the calibration of optical fibre geometry test sets

IEC 61745:2017 describes the calibration of test sets that perform end-face image analysis, also known as "near-field" or "grey-scale" analysis. The principles, however, can be applied to test sets of a different type. The procedures outlined are performed by calibration laboratories and by the manufacturers or users of geometry test sets, for the purpose of calibrating geometry test sets and for evaluating the uncertainties in measurements made on calibrated test sets. The calibration of fibre coating or cable measurement test sets is not covered by this document. This second edition cancels and replaces the first edition, published in 1998, and constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition: a) removal of the limitation of single mode optical fibre geometry test sets to include multimode; b) addition of a new annex as mathematical basis. Keywords: end-face image analysis, optical fibre geometry test sets

Endflächen-Bildanalyseverfahren für die Kalibrierung von Prüfeinrichtungen für die Geometrie von Lichtwellenleitern

Procédure d'analyse d'image d’extrémité pour l'étalonnage de dispositifs d'essais de géométrie des fibres optiques

IEC 61745:2017 décrit l'étalonnage de dispositifs d'essais qui effectuent une analyse d'image d’extrémité, également appelée "analyse de champ proche" ou "analyse d'échelle de gris". Les principes peuvent toutefois être appliqués à des dispositifs d'essais d'un type différent. Les procédures indiquées sont réalisées par des laboratoires d'étalonnage et par les fabricants ou les utilisateurs de dispositifs d'essais de géométrie, à des fins d'étalonnage de dispositifs d’essais de géométrie et d'évaluation des incertitudes des mesures effectuées sur des dispositifs d'essais étalonnés. Le présent document ne couvre pas l'étalonnage de dispositifs d’essais de mesure de câbles ou de revêtements de fibres. Cette deuxième édition annule et remplace la première édition parue en 1998, dont elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) retrait de la restriction des dispositifs d'essais de géométrie aux fibres optiques unimodales pour inclure les fibres optiques multimodales; b) ajout d'une nouvelle annexe portant sur les bases mathématiques. Mots clés: analyse d’image d’extrémité, essais de géométrie des fibres optiques

Postopek analize čelne slike za umerjanje pribora za preskušanje geometrije optičnih vlaken (IEC 61745:2017)

Ta dokument opisuje kalibracijo kompletov preskusov, ki izvajajo analizo čelne slike, imenovano tudi analiza bližnjega polja (»near-field«) oziroma analiza lestvice sivih tonov (»grey-scale«). Načela se lahko uporabijo za različne vrste kompletov preskusov.
Opisane postopke izvajajo kalibracijski laboratoriji in proizvajalci ali uporabniki geometrijskih kompletov preskusov za namene kalibriranja geometrijskih kompletov preskusov in ocenjevanja negotovosti pri meritvah, izvedenih v okviru kalibriranih kompletov preskusov. Dokument ne zajema kalibracije kompletov preskusov za premaz vlaken ali meritve kablov.
