International audience; We report on the use of a radial acoustic resonator to increase the acoustic signal of a quartz enhanced photoacoustic spectroscopy (QEPAS) sensor. This approach is an attractive alternative to usual configurations based on mi

Photoacoustic spectroscopy is a detection method enabling a strong multi-gas capacity. Instead of using photodetectors, the detection is realised in the acoustic domain by using microphones, making the detection independent from the optical wavelengt

Nouvelles approches pour l'imagerie photoacoustique des vaisseaux sanguins : imagerie quantitative 3D de fluctuations et reconstruction assistée par apprentissage profond

Autor: Godefroy, Guillaume

Vascular imaging is of considerable interest for many health applications, including pathology diagnosis, surgical guidance, medical monitoring and biomedical research. While several modalities are currently used to image blood vessels, bimodal devic

Imagerie photoacoustique au-delà de la limite de diffraction acoustique

Publikováno v: Instrumentation and Detectors [physics.ins-det]. Université Grenoble Alpes, 2019. English. ⟨NNT : 2019GREAY035⟩

Wave imaging remained diffraction-limited for centuries, until methods, such as PALM, STORM and STED were proposed in optics. Thanks to such methods, imaging with a precision much better than the wavelength became possible.Inspired by these super-res

International audience; In this paper, we report the first analytical model for quartz-enhanced photoacoustic spectroscopy in combination with an acoustic resonator. A generalized fundamental equation is proposed to model the photoacoustic effect, ta
