New Publication on Optics Letters

The PolySense team has just published  a new article on Optics Letters reporting on a side-excitation light-induced thermoelastic spectroscopy (SE-LITES) technique for trace gas detection. The mechanical stress distribution on the QTF surface was analyzed to identify the optimum thermoelastic excitation approach. A signal-to-noise ratio (SNR) improvement of more than one order of magnitude was Leggi di piùNew Publication on Optics Letters[…]

New Publication on Photoacoustics Journal

The PolySense team has just published  a new article on Photoacoustics Journal Elsevier (IF 9.94)  reporting on the development of a gas sensor based on light-induced thermo-elastic spectroscopy (LITES) capable to detect methane (C1) and ethane (C2) in a wide concentration range, from percent down to part-per-billion (ppb). Minimum detection limits of ∼650 ppb and Leggi di piùNew Publication on Photoacoustics Journal[…]
