Title: Novel micro-nano fiber evanescent wave quartz-enhanced photoacoustic spectroscopy
In this paper, a long distance, distributed gas sensing system was reported based on a new technique of micro-nano fiber evanescent wave quartz enhanced photoacoustic spectroscopy (FEW-QEPAS). Such a sensor scheme has the advantages of higher detection sensitivity, distributed gas sensing ability, lower cost and a simpler fabrication procedure compared to conventional FEW gas sensors using photonic crystal fibers or tapered fibers with chemical sputtering. A fiber with multiple tapered detection units in FEW-QEPAS system was used to investigate long distance and distributed sensing based on multi-point, spatially resolved trace gas concentration measurements.
