Compact all-fiber photoacoustic spectrometer for intravascular gas detection comparable to laboratory-based systems

Fiber photoacoustic spectrometer allows continuous intravascular gas monitoring. Credit: Jun Ma (Jinan University) Compact spectroscopic systems capable of detecting trace concentrations at parts per billion (ppb) levels are of paramount importance in applications ranging from environmental monitoring and industrial process control to biomedical diagnostics. However, existing benchtop spectroscopy systems are too large, complex, and impractical for use in confined spaces.…
