Lub hauv paus ntsiab lus thiab kev siv cov ntsuas kub infrared
Tus pas ntsuas kub infrared hloov lub zog hluav taws xob ntawm cov kab hluav taws xob infrared tawm los ntawm cov khoom mus rau hauv cov teeb liab hluav taws xob. Qhov loj ntawm lub zog infrared radiant sib haum rau qhov kub ntawm qhov khoom nws tus kheej. Raws li qhov loj ntawm lub teeb liab hloov hluav taws xob, qhov kub ntawm qhov khoom tuaj yeem txiav txim siab.
1. Lub hauv paus ntsiab lus ntawm infrared tus pas ntsuas kub
Tus pas ntsuas kub infrared yog tsim los ntawm optical system, photoelectric detector, teeb liab amplifier, teeb liab ua, tso zis tso zis thiab lwm yam. Lub tshuab kho qhov muag sib sau ua ke lub hom phiaj infrared hluav taws xob hluav taws xob hauv nws qhov chaw saib, thiab qhov loj ntawm qhov kev pom yog txiav txim los ntawm qhov chaw kho qhov muag ntawm tus pas ntsuas kub thiab nws txoj hauj lwm. Lub zog infrared yog tsom rau lub photodetector thiab hloov mus rau hauv cov teeb liab hluav taws xob sib xws. Lub teeb liab dhau los ntawm lub amplifier thiab teeb liab ua Circuit Court, thiab hloov mus rau hauv tus nqi kub ntawm qhov ntsuas lub hom phiaj tom qab raug kho raws li algorithm ntawm kev kho sab hauv ntawm lub ntsuas thiab emissivity ntawm lub hom phiaj.
Nyob rau hauv qhov xwm txheej, txhua yam khoom uas muaj qhov kub siab tshaj xoom yog tas li emitting infrared hluav taws xob hluav taws xob mus rau qhov chaw nyob ib puag ncig. Qhov loj ntawm lub zog hluav taws xob infrared ntawm ib yam khoom thiab nws qhov kev faib tawm raws li lub wavelength - muaj kev sib raug zoo nrog nws qhov kub thiab txias. Yog li, los ntawm kev ntsuas lub zog infrared radiated los ntawm cov khoom nws tus kheej, nws qhov kub thiab txias tuaj yeem txiav txim siab, uas yog lub hauv paus rau kev ntsuas kub ntawm infrared radiation.
Lub hauv paus ntsiab lus ntawm Infrared Thermometer Blackbody yog lub tshuab hluav taws xob zoo tshaj plaws, uas absorbs tag nrho cov wavelengths ntawm lub zog hluav taws xob, tsis muaj kev xav thiab kev xa tawm ntawm lub zog, thiab muaj emissivity ntawm 1 ntawm nws qhov chaw. Txawm li cas los xij, cov khoom siv hauv qhov xwm txheej yuav luag tsis yog lub cev dub. Txhawm rau kom paub meej thiab tau txais kev faib tawm ntawm cov hluav taws xob infrared, ib qho qauv tsim nyog yuav tsum raug xaiv hauv kev tshawb fawb theoretical. Qhov no yog qhov quantized oscillator qauv ntawm lub cev kab noj hniav hluav taws xob tau npaj los ntawm Planck, yog li muab tau txoj cai ntawm Planck lub cev dub hluav taws xob, uas yog, lub cev dub spectral radiance qhia los ntawm wavelength, uas yog qhov pib ntawm tag nrho cov infrared radiation theories, yog li nws yog. hu ua txoj cai ntawm lub cev dub tawg. Tus nqi hluav taws xob ntawm tag nrho cov khoom tiag tiag nyob ntawm tsis yog tsuas yog nyob ntawm qhov hluav taws xob wavelength thiab qhov kub ntawm cov khoom, tab sis kuj yog nyob ntawm hom khoom tsim los ntawm cov khoom, cov txheej txheem kev npaj, txheej txheem thermal, lub xeev saum npoo thiab ib puag ncig. Yog li ntawd, txhawm rau ua kom txoj cai lij choj ntawm lub cev dub hluav taws xob siv tau rau txhua yam khoom siv, ib qho kev faib ua feem coefficient ntsig txog cov khoom siv thiab lub xeev saum npoo yuav tsum tau qhia, uas yog, emissivity. Qhov coefficient no txhais tau hais tias kaw lub thermal hluav taws xob ntawm ib qho khoom tiag tiag rau cov hluav taws xob ntawm lub cev dub, thiab nws tus nqi yog nyob nruab nrab ntawm xoom thiab tus nqi tsawg dua 1. Raws li txoj cai ntawm hluav taws xob, tsuav yog qhov emissivity ntawm cov khoom siv. paub, cov yam ntxwv ntawm infrared radiation ntawm tej yam khoom yog paub. Cov yam tseem ceeb cuam tshuam rau emissivity yog: hom khoom, nto roughness, lub cev thiab tshuaj qauv, thiab cov khoom thickness.
Thaum siv lub ntsuas hluav taws xob hluav taws xob infrared los ntsuas qhov ntsuas kub ntawm lub hom phiaj, nws yog thawj zaug uas yuav tsum ntsuas qhov hluav taws xob infrared ntawm lub hom phiaj nyob rau hauv nws cov band range, thiab tom qab ntawd qhov ntsuas kub ntawm lub hom phiaj ntsuas yog xam los ntawm tus pas ntsuas kub. Ib qho monochromatic pyrometer yog proportional rau tus nqi hluav taws xob hauv ib pawg; ib tug ob-xim pyrometer yog proportional rau qhov piv ntawm tus nqi hluav taws xob nyob rau hauv ob bands.
Thib ob, kev siv cov ntsuas kub infrared
Infrared tus pas ntsuas kub yog ib qho kev ntsuas kub uas feem ntau siv los ntsuas qhov ntsuas, feem ntau yog tsim los ntawm optical system, photodetector, teeb liab amplifier, teeb liab ua, tso zis tso zis thiab lwm yam, thiab yog dav siv nyob rau hauv ntau industries. Niaj hnub no peb tsuas yog qhia txog daim ntawv thov ntau yam ntawm cov ntsuas kub infrared, vam tias yuav pab cov neeg siv khoom siv tau zoo dua.
