Abstract

Un élément 9 mobile avec l'organe présente deux pistes différentes en partie réfléchissante à l'égard desdites impulsions, une première 11 desdites pistes étant réfléchissante sauf pour une zone restreinte témoin d'une première des deux positions normales de l'organe, une seconde 12 desdites pistes étant réfléchissante sauf pour une zone restreinte témoin d'une seconde desdites deux positions normales. Un système de fibres optiques 3, 7, 8 conduit des impulsions lumineuses de moyens d'émission 1 à des extrémités fixes de couplage optique avec respectivement chacune desdites pistes et les impulsions résultant d'une réflexion éventuelle en retour jusqu'à des moyens de réception 2. Il impose des trajets optiques de longueurs différentes pour respectivement chacune desdites pistes. On recueille les impulsions éventuellement réfléchies par l'une et l'autre pistes dans un signal comportant en outre une impulsion d'écho indépendante de la différence des trajets.
