Abstract

L'invention porte sur un verrou de longueurs d'onde pouvant agir sur plusieurs longueurs d'onde comportant des filtres de différentes caractéristiques par détecteur correspondant. Les filtres peuvent être des étalons de différentes plages spectrales libres, par exemple présentant différentes épaisseurs apparentes ou réelles. Si plus de trois de ces filtres émettent des signaux périodiques de décalage, on peut éliminer un détecteur de référence et effectuer une opération continue sur une plage de longueurs d'onde.
