Abstract

Eine Vorrichtung (10) zur Bestimmung der Absorption einer Probe, enthaltend eine Inkohärente Strahlungsquelle (12) zur Erzeugung eines Messlichtstrahls (20), einen Resonator (14) mit wenigstens zwei Spiegeln (30, 32), in welchen der Messlichtstrahl einkoppelbar ist, ein Probenvolumen (38) zur Aufnahme einer absorbierenden Probe innerhalb des Resonators (14) und einen Detektor (18) zur Aufnahme der Strahlung, welche aus dem Resonator (14) auskoppelbar ist, ist dadurch gekennzeichnet, dass zwischen der Strahlungsquelle (12) und dem Detektor (18) spektrometrische oder interferometrische Mittel (16) zur spektralen Zerlegung des Messlichtstrahls vorgesehen sind und Mittel zur Erzeugung eines Signals vorgesehen sind, welches phasenunabhängig die Amplitude des Messlichtstrahls repräsentiert.
