基于激光干涉测温技术的火焰温度场研究 Title:ResearchonFlameTemperatureFieldBasedonLaserInterferometricTemperatureMeasurementTechnique Abstract: Flametemperatureisacriticalparameterinvariousfields,includingcombustion,energyconversion,andenvironmentalengineering.Accuratemeasurementandunderstandingoftheflametemperaturefieldcanhelpoptimizecombustionprocesses,improveenergyefficiency,andminimizepollutantemissions.Thispaperfocusesonthestudyofflametemperaturefieldusinglaserinterferometrictemperaturemeasurementtechnique. Introduction: Themeasurementofflametemperaturehastraditionallybeenachallengingtaskduetotheharshanddynamicnatureofcombustionenvironments.Conventionaltemperaturemeasurementmethods,suchasthermocouplesandpyrometry,oftensufferfromlimitedspatialandtemporalresolution.Inrecentyears,laserinterferometrictemperaturemeasurementtechniqueshaveemergedasapromisingapproachtoovercometheselimitations.Thispaperaimstoexplorethecapabilitiesandpotentialapplicationsoflaserinterferometryinstudyingtheflametemperaturefield. PrincipleofLaserInterferometricTemperatureMeasurementTechnique: Laserinterferometrictemperaturemeasurementtechniqueisbasedontheprincipleofinterferometry,whichutilizestheinterferencepatternsoflaserbeamstomeasuretemperaturevariations.Inthistechnique,twocoherentlaserbeamsaregeneratedanddirectedtowardstheflame.Onebeampassesthroughtheflamewhiletheotherservesasareference.Theinterferencepatternbetweenthetwobeamsiscapturedusingahigh-resolutioncamera,andchangesintheinterferencefringesareanalyzedtodeterminetheflametemperature.
