  • Gas-detecting device with very high sensitivity based on a Helmholtz resonator
    Patent number: 10876958
    Abstract: The invention relates to a device comprising: a resonant tank (100) consisting of two primary tubes (105, 106) which are closed on the ends thereof and interconnected, close to each of the ends thereof, by two secondary tubes (109, 110), and provided with a gas-introducing means (118, 119); a first laser source (112) modulated to a first resonance frequency of the tank, which supplies an excitation energy in at least one of the primary tubes, with an emission wavelength corresponding to a local maximum absorption wavelength for a first gas, for generating a first stationary wave propagating along the secondary tubes; a second laser source (117) modulated to a second resonance frequency of the tank, which supplies an excitation energy in at least one of the secondary tubes, with an emission wavelength corresponding to a local maximum absorption wavelength for a second gas, for generating a second stationary wave propagating along the primary tubes; at least one acoustoelectric transducer (103, 104, 123, 124) a
