Abstract:
Modular photoacoustic detection device comprising: a photoacoustic cell including at least two chambers connected by at least two capillaries and forming a Helmholtz type differential acoustic resonator; acoustic detectors coupled to the chambers; a light source capable of emitting a light beam having at least one wavelength capable of exciting a gas intended to be detected and which can be modulated to a resonance frequency of the photoacoustic cell; a first photonic circuit optically coupling the light source to an input face of a first of the chambers; wherein the first photonic circuit is arranged in a detachable manner in a first housing formed in the acoustic cell and emerging on the input face of the first chamber.

Claim (Index 16):
A method according to  claim 15 , wherein:\n the production of the photoacoustic cell comprises the production of at least one stack of a first and of a second layer of material in which are formed, by chemical etching implemented in a part of the thickness of each of the first and second layers, the chambers, the capillaries, the first housing, at least two openings each emerging in one of the capillaries and at least two locations each communicating with one of the chambers and in which the acoustic detectors are arranged, or the production of the photoacoustic cell comprises the production of at least one stack of a first, second, third and fourth layers of material in which are formed, by chemical etching or laser implemented in the entire thickness of each of the second, third and fourth layers, the chambers, the capillaries, the first housing, at least two openings each emerging in one of the capillaries and at least two locations each communicating with one of the chambers and in which the acoustic detectors are arranged, or the photoacoustic cell is formed of a monolithic part of sintered metal powders obtained by 3D printing.
