New Publication on Applied Science

The PolySense team has just published  a new article on Applied Science reporting on the theoretical analysis and experimental investigation of the influence of gas pressure on resonance properties, namely, the quality factor and resonance frequency, of a T-shaped quartz tuning fork (QTF).  The results show that acoustic coupling is strongly influenced by air pressure, Leggi di piùNew Publication on Applied Science[…]

New Publication on Optics Express

The PolySense team has just published  a new article on OSA Optics Express Journal reporting on a novel an ultra-highly sensitive light-induced thermoelastic spectroscopy (LITES)-based carbon monoxide (CO) sensor exploiting custom quartz tuning forks (QTFs) as a photodetector, a multi-pass cell and a mid-infrared quantum cascade laser (QCL). At an integration time of 200 ms a minimum Leggi di piùNew Publication on Optics Express[…]

New Publication on Optics Letters

The PolySense team has just published  a new article on OSA Optics Letters Journal reporting on a novel multi-pass quartz-enhanced photoacoustic spectroscopy-based trace gas sensor . The multi-pass configuration allows the laser beam to pass through the QTF prong spacing six times. Compared to a conventional QEPAS measurement, the MP-QEPAS technique provided an enhancement of signal Leggi di piùNew Publication on Optics Letters[…]
