A gas sensing system having a networked web of gas sensors having an ability to detect a chemical species in a gas sensor has a beam emitter that emits a first beam comprising laser, a beam-splitting interferometer, a spectrometer and a detector, wherein the first beam is to strike the gas that produces a second beam comprising a Raman signal, the beam-splitting interferometer is to create a phase delay in the second beam is disclosed. The gas sensing system could be used for spectroscopic detection of ethylene by generating a first beam comprising laser, striking the first beam to a gas comprising ethylene to produce a second beam comprising a Raman signal, creating a phase delay in the second beam, passing the second beam through a spectrometer and detecting a Raman signature of ethylene. The gas sensing system could be used for the determination of the extent of ripening in a specific field area. |
