Paper Abstract

In this work we analyze two aspects of our research towards a laser-based setup for open-path hydrogen sulfide detection. We demonstrate a compact and portable electronic part of the sensing system that can be constructed solely with commercially available, off-the-shelf components. Comparison with the setup that uses benchtop lock-in amplifier for signal demodulation is presented. We also discuss challenges in spectral modelling of H2S transitions in the near-IR spectral region using the data available in HITRAN base. We show that in order to perform correct spectral simulations (for both direct absorption spectroscopy and wavelength modulation spectroscopy) appropriate corrections to the data available in the database have to be applied.
