Abstract

Selon ce procédé de détection optique d'une variable électrique (I), une dépendance périodique est établie entre le signal de mesure optique et la variable électrique à mesurer (I). Afin d'obtenir un signal de mesure univoque, il est prévu d'utiliser deux signaux de mesure optiques présentant une dépendance périodique. Les valeurs mesurées servent de paire de valeurs pour affecter de façon univoque une valeur absolue de la variable électrique (I).
