Abstract: Une source lumineuse produit des faisceaux laser qui sont soumis à la modulation de fréquence dont la fréquence peut être adéquatement définie ou modifiée. Un modulateur de lumière module les faisceaux laser par rapport à la longueur d'onde du centre, afin que la bande latérale inférieure soit utilisée comme entrée de sonde lumineuse dans une extrémité de la fibre optique mesurée. Un modulateur d'impulsions produit des impulsions laser basées sur des faisceaux laser en tant que lumière de pompage, qui est communiquée à l'autre extrémité de la fibre optique mesurée, les pics de corrélation apparaissant à des positions différentes de sa longueur. La lumière de sortie est extraite de l'autre extrémité de la fibre optique mesurée et est fournie à un dispositif de réglage de synchronisation, qui permet de régler un moment de transmission pour permettre la transmission de la lumière proche d'un point de mesure dans la fibre optique mesurée passant par celui-ci. Ainsi, il est possible de mesurer de façon fiable les caractéristiques de la fibre optique mesurée sur toute la distance relativement longue avec des résolutions spatiales élevées.
