Abstract (English)

This thesis provides a detailed theoretical discussion about common absorption spectroscopy (AS) and, in particular, about photoacoustic spectroscopy (PAS). The physical concepts of signal generation are illustrated in view of amplitude modulation (AM) and wavelength modulation (WM). Furthermore the advantages and disadvantages of the techniques are presented. As a result, PAS was identified to ...

Translation of the abstract (German)

Die vorliegende Arbeit präsentiert eine detaillierte Beschreibung des Messprinzips der Absorptionsspektroskopie (AS) und im Speziellen der photoakustischen Spektroskopie (PAS). Die Vor- und Nachteile beider Prinzipien werden sowohl auf Grundlage der Amplitudenmodulation (AM) als auch der Wellenlängenmodulation (WM) herausgearbeitet. Darüber hinaus werden mögliche Ansätze zur Signaloptimierung (z. ...
