Photoacoustic spectroscopy detection based on complementary interdigital cantilever enhanced Fabry-Perot acoustic sensor
Year: 2025
Type: article
Abstract: at 1 kHz. In the concentration range of 20 ppm to 100 ppm, the sensitivity of PAS to C₂H₂ gas was 3.02 pm/ppm and the detection limits of C₂H₂ in N₂ background was 30.17 ppb. This design employs highly sensitive cantilevers with tunable resonance, enhancing the gas detection sensitivity of the PAS system by leveraging resonant frequency matching and signal amplification.
