Abstract

Verfahren zur Bestimmung des Phasenunterschiedes zwischen zwei Frequenzbändern im Frequenzspektrum einer elektromagnetischen Probestrahlung (5) aufweisend folgende Schritte: - Die Probestrahlung (5) wird in mindestens einen Lichtleiter (3, 4) eingekoppelt, in dem oder denen sie sich jeweils in Ausbreitungsrichtung ausbreitet. - In den oder die Lichtleiter (3, 4) wird jeweils eine Pumpstrahlung A, B einer bekannten Frequenz entgegen der Ausbreitungsrichtung der Probestrahlung (5) eingekoppelt. - Die Frequenz der einen ersten Pumpstrahlung A wird derart gewählt, dass ein schmales erstes Frequenzband der Probestrahlung (5) durch stimulierte Brillouin Streuung verstärkt (SBS-Gewinn) wird. - Die Frequenz der anderen zweiten Pumpstrahlung B wird derart gewählt, dass ein schmales zweites Frequenzband der Probestrahlung (5) durch SBS verstärkt wird. - Die Frequenz des ersten Frequenzbandes wird durch eine Modulation so verändert, dass sie mit der Frequenz des zweiten Frequenzbands übereinstimmt. - Die beiden verstärkten Frequenzbänder werden in einem gemeinsamen Strahl vereint, wobei die Amplitude der entstehenden Überlagerung in einem Detektor (11) registriert wird.
