Herriott cell spot imaging increases the performance of tunable laser spectrometers

Christopher R. Webster et al.

Summary: The new laser detection technology combines detector arrays and infrared lenses, improving sensitivity, increasing dynamic range, normalizing laser power, reducing optical interference, enhancing stability, and reducing instrument power consumption. By using multi-point imaging scans, it is possible to select and manipulate pixel output spectra to minimize optical interference fringes, thereby increasing sensitivity.

Parts-per-billion detection of carbon monoxide: A comparison between quartz-enhanced photoacoustic and photothermal spectroscopy

Davide Pinto et al.

Summary: This study compared two optical detection techniques based on QEPAS and PTS, which directly detect acoustic waves and probe refractive index variations to detect optical absorption phenomena in gases. Compact QEPAS and PTS detection modules were integrated into a gas sensor system for CO detection, achieving ultimate detection limits of -6 ppb and -15 ppb, respectively.

Comparison of laser-based photoacoustic and optical detection of methane

Thomas Strahl et al.

Summary: The article highlights the importance of using laser spectroscopy for measuring low methane concentrations, compares the detection performance of direct absorption spectroscopy and photoacoustic spectroscopy at different infrared wavelength ranges, and demonstrates that photoacoustic spectroscopy achieves lower detection limits and higher system stabilities in the long-wavelength infrared range.
