Abstract[English]
), arranged such that an optical delay-line beam (11) coupled into the delay line assembly (1) is able to propagate along a rotation-dependent delay path between a spatially fixed input point (IN) and a spatially fixed output point (OUT), wherein the rotation-dependent delay path comprises at least two reflections off the first plane mirror surface of each mirror pair offset from each other in a direction parallel to the rotation axis, at least two reflections off the second plane mirror surface of each mirror pair offset from each other in a direction parallel to the rotation axis, and at least two reflections off each fixed reflector device offset from each other in a direction parallel to the rotation axis (A).[French]
), agencés de telle sorte qu'un faisceau de ligne à retard optique (11) couplé dans l'ensemble ligne à retard (1) peut se propager le long d'un chemin de retard dépendant de la rotation entre un point d'entrée (ENTRÉE) spatialement fixe et un point de sortie (SORTIE) spatialement fixe, le chemin de retard dépendant de la rotation comprenant au moins deux réflexions sur la première surface de miroir plan de chaque paire de miroirs décalées l'une de l'autre dans une direction parallèle à l'axe de rotation, au moins deux réflexions sur la seconde surface de miroir plan de chaque paire de miroirs décalées l'une de l'autre dans une direction parallèle à l'axe de rotation, et au moins deux réflexions sur chaque dispositif réflecteur fixe décalées l'une de l'autre dans une direction parallèle à l'axe de rotation (A).
