Continuous development of new coherent light sources operating especially in the Mid-IR spectral band (QCL-Quantum Cascade Lasers, ICL-Interband Cascade Lasers, OPO-Optical Parametric Oscillator, DFG-Difference Frequency Generation, optical frequency combs, etc.) stimulates new, sophisticated methods and technological solutions in this area. The development of clever techniques in gas detection based on new mechanisms of sensing (photoacoustic, photothermal, dispersion, etc.) supported by advanced applied electronics and huge progress in signal processing allows us to introduce more sensitive, broader-band and miniaturized optical sensors. Additionally, the substantial development of fast and sensitive photodetectors in MIR and FIR is of great support to progress in gas sensing. Recent material and technological progress in the development of hollow-core optical fibers allowing low-loss transmission of light in both Near- and Mid-IR has opened a new route for obtaining the low-volume, long optical paths that are so strongly required in laser-based gas sensors, leading to the development of a novel branch of laser-based gas detectors. This Special Issue summarizes the most recent progress in the development of optical sensors utilizing novel materials and laser-based gas sensing techniques.Optical Gas SensingHistory of engineering & technologybicsscTechnology: general issuesbicsscabsorption spectroscopyair pollution monitoringanalytic modelantiresonant hollow core fiberscantilevercapacitive detectionCO2combined NIR/MIR laser absorptionderivative absorption spectroscopydilution methodeddy covariance methodFabry-Perot cavityfemtosecond laser micromachiningfiber gas sensorsflow simulationflow speedflow turbulenceflux measurementfourier transformfrequency combgas modulationgas sensinggas sensing applicationsgas sensorgas sensorsheterodyne detectionhigh-resolution spectroscopyhigh-speed operationimage processinginfrared imagingintegrated sensorsisotopic ratiolaser flow meterlaser gas analyzerlaser multiplexing in a mid-IR single-mode fiberlaser spectroscopyMEMSmetrologymicrochannel fabricationmicrostructured fibersmid-infraredmodulation techniquesmultispectral and hyperspectral imagingphotoacousticphotoacoustic spectroscopyphotoacousticsphotothermal spectroscopyPitot tubepressurepressure transducerquantum cascade detectorRaman spectroscopyrefractometryremote sensing and sensorsshort-term performancesimultaneous multispecies (CO, CO2, H2O) in situ measurementsspectroscopytime of flighttunable diode laser absorption spectroscopyVernier spectroscopywafer-levelwaveguideswavelength modulation spectroscopyHistory of engineering & technologyTechnology: general issuesAbramski Krzysztof Medt1319553Jaworski PiotredtAbramski Krzysztof MothJaworski PiotrothBOOK9910566467103321Optical Gas Sensing: Media, Mechanisms and Applications3033958UNINA
