Yuav Ua Li Cas Xaiv Txoj Cai Tus Ntsuas Kub Khoom Taw Qhia
Tus ua haujlwm ua haujlwm ntawm infrared thermometers tau piav qhia txog kev ua haujlwm hauv chav tsev kawm ntawv qib siab, ib txoj kev rau xaiv cov ntsuas hluav taws xob tsis tsim nyog.
Qhov ntsuas kub ntsuas ntawm tus pas ntsuas kub infrared yog hloov hluav taws xob hluav taws xob tawm los ntawm cov khoom (xws li molten hlau) mus rau hauv lub cim hluav taws xob. Qhov ntau ntawm cov hluav taws xob hluav taws xob hluav taws xob sib raug zoo rau qhov kub ntawm cov khoom (xws li Molten Hlau) nws tus kheej. Raws li qhov ntau ntawm cov teeb liab hloov dua siab tshiab, qhov kub ntawm cov khoom (xws li Molten Hlau) tuaj yeem txiav txim siab.
Tus pas ntsuas kub infrared muaj cov qauv siv kho qhov muag, lub teeb liab amplifier, teeb liab kev ua, tso tawm cov zis, thiab lwm yam. Lub cev kho qhov muag pom zoo ntawm lub zog hluav taws xob infriation lub zog ntawm lub hom phiaj hauv nws qhov kev pom, thiab qhov loj ntawm kev pom yog txiav txim siab los ntawm kho qhov muag. Lub zog infrared yog tsom rau lub photodetector thiab hloov mus rau hauv cov cim hluav taws xob sib xws, thiab ntsuas pom tau raws li lub teeb liab thiab lub hom phiaj emissivity ntawm lub ntsuas
Nyob rau hauv xwm, txhua yam khoom nrog kub saum toj kawg nkaus xee yog tas li tsis tu ncua hluav taws xob lub zog mus rau qhov chaw ib puag ncig. Qhov loj me thiab wavelength faib ntawm infrared hluav taws xob lub zog ntawm ib qho khoom muaj feem cuam tshuam nrog nws qhov kub. Yog li ntawd, los ntawm kev ntsuas lub zog infrared los ntawm ib qho khoom nws tus kheej, nws qhov chaw kub tuaj yeem txiav txim siab tau, uas yog lub hom phiaj ncaj qha rau kev ntsuas ntsuas kub infriation infriation.
Ib tug neeg dub yog qhov zoo tshaj plaws radiator uas nqus hluav taws xob muaj zog ntawm txhua lub zog lossis cov khoom siv tiag tiag uas muaj nyob rau hauv qhov xwm txheej yog yuav luag tsis yog blackbodies. Txhawm rau kom hais meej thiab tau txais kev faib tawm txoj cai ntawm kev ntsuas hluav taws xob infriation, ib tus qauv tsim nyog yuav tsum raug xaiv hauv theoretical kev tshawb fawb. Qhov no yog cov Quantized oscillator qauv ntawm lub cev kab noj hniav hluav taws xob tau npaj los ntawm Dub Mirdians ntawm Blackbody Radiation qhia nyob rau hauv wavelength. Qhov no yog qhov pib ntawm txhua qhov hluav taws xob ntsuas hluav taws xob theoriariation, li no nws yog hu ua Blackbody Browiay txoj cai lij choj. Kev ntsuas hluav taws xob ntawm txhua qhov khoom siv hluav taws xob nyob ntawm tsis tsuas yog nyob ntawm cov khoom siv hluav taws xob thiab kub, tab sis kuj tseem muaj cov txheej txheem, thiab ib puag ncig lub xeev, thiab ib puag ncig cov mob uas ua rau cov khoom. Yog li ntawd, txhawm rau ua kom tus Dub Tsis Muaj Peev Xwm Hluav Taws Xob uas muaj feem xyuam nrog cov khoom siv thiab cov xeev tau xwm txheej, yuav tsum tau ua qauv. Qhov no coefficent sawv cev rau cov qib uas lub thermal hluav taws xob ntawm cov khoom siv hluav taws xob zoo nkauj, muaj nuj nqis ntawm cov khoom muaj txiaj ntsig ntawm 1. Lub ntsiab tseem ceeb cuam tshuam nrog kev ua emissivity suav nrog cov khoom siv, nto roughness, lub cev thiab cov ntaub ntawv tuab.
