Interference filter tilting to detect a polycyclic aromatic hydrocarbon at the second harmonic of wavelength modulation frequency

We present a practical implementation of the wavelength-modulation spectroscopy technique with second-harmonic detection (WMS-2f) for selective detection and concentration measurements of polycyclic aromatic hydrocarbons (PAHs) - common fossil fuel pollutants. The method is based on excitation light...
