English term

mode converted signal

English to French Tech/Engineering Science (general) Analyse de défauts dans soudure
Bonjour,

Comment traduire 'mode converted signal' ?
Le texte concerne l'analyse de soudures à la recherche de défaut à l'aide d'un scanner pour tube soudés.

This allowed us to view each indication along the scan access, the A-scan where the cursor is placed, and the R/S scan showing where the indications are positioned* within the weld.
We observed the data in the A gate to verify whether it plotted accurately, keeping in mind that additional indications appear from mode converted signal.

Merci

@ Asker Working from Marielle's suggestion, I'd say it is more like a 'signal ayant subi une conversion de mode'.
Tony M Dec 3, 2018:
@ Asker: Context? I'm afraid only more details of your context will probably help us here; in particualr, we need to know between which 'modes' this signal / data might be being converted.
This EN has a curious ring to it, I'm suspecting a non-native writer and/or prior translation.
In certain contexts involving Fourier transforms, we can find analysis signals being converted between domains: the time and the frequency domains; but it's not clear to me from the available context whether a) this analysis is in any way related to this field, and b) whether 'mode' is an error for 'domain' or not?

signal généré par conversion de mode

Il s'agit de contrôle par ultrasons.

cf. p. 6 dans http://perso.univ-lemans.fr/~cpotel/lefebvre_potel_A&T_02200...
"Si grâce à l’interaction avec l’interface, une onde de nature différente (TV par exemple) de celle de l’onde incidente (L par exemple) est générée, on dit qu'il y a conversion de mode"

cf. https://www.iso.org/obp/ui/#iso:std:iso:5577:ed-2:v1:en + https://www.iso.org/obp/ui/#iso:std:iso:5577:ed-2:v1:fr:term...
"wave mode conversion" = "conversion du mode de transmission d'onde"
Peer comment(s):

neutral Tony M : Yes, but it isn't the 'mode conversion' that generates the signal: it is the signal being generated from one form to another that is referred to as 'mode conversion'; so although your explanations are correct, I think your inferred translation is wrong.

si "généré" est problématique (bien qu'utilisé, cf. réf) : "signal résultant de la conversion de mode" ou "signal issu de la conversion de mode"
