H2S photoacoustic detection with an integrated THz gas sensor for food quality control

Résumé

THz photoacoustic (PA) detection of H 2 S gas concentrations on the order of 200 ppm using a Poly-Si membrane as a PA microphone is reported. This result is a first step towards the demonstration of a fully integrated THz PA gas sensor with an expected sensitivity of 10’s of ppb.
