Tus pas ntsuas kub infrared yuav tsum tau xaiv kom raug.
Kev ntsuas kub infrared thev naus laus zis ua lub luag haujlwm tseem ceeb hauv kuv lub teb chaws cov khoom lag luam zoo tswj thiab saib xyuas, cov cuab yeej siv online tsis raug kuaj xyuas, kev tiv thaiv thiab kev txuag hluav taws xob. Hauv ob xyoos dhau los, cov ntsuas kub tsis sib cuag infrared tau tsim kho sai hauv kev siv thev naus laus zis, lawv cov kev ua tau zoo tsis tu ncua, lawv cov peev txheej ntawm daim ntawv thov tau nthuav dav ntxiv, thiab lawv txoj kev lag luam tau nce xyoo los ntawm xyoo. Piv nrog rau kev ntsuas kub ntawm kev sib cuag, kev ntsuas kub infrared muaj qhov zoo ntawm lub sijhawm teb ceev, tsis sib cuag, siv ntev thiab kev pabcuam lub neej. Cov ntsuas suab nrov digital kuj tseem ua lub luag haujlwm hauv kev ntsuas suab nrov.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm tus pas ntsuas kub sab nraud:
Kev nkag siab txog kev ua haujlwm, cov ntsuas kev ua haujlwm, ib puag ncig kev ua haujlwm, kev ua haujlwm thiab kev saib xyuas cov ntsuas kub sab nraud yog pab cov neeg siv xaiv thiab siv cov ntsuas kub infrared.
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. Cov yam ntxwv ntawm cov hluav taws xob infrared ntawm ib yam khoom - qhov loj ntawm lub zog hluav taws xob thiab nws qhov kev faib tawm los ntawm wavelength - yog ze ze rau 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 ntsuas qhov tseeb. Qhov no yog lub hom phiaj ntawm lub hauv paus ntawm qhov ntsuas kub ntawm infrared radiation.
Thermometer dub lub cev hluav taws xob txoj cai:
Lub cev dub yog ib qho zoo tagnrho radiator uas absorbs radiant zog ntawm tag nrho cov wavelengths tsis muaj lub zog xav txog los yog kis tau tus mob, thiab nws nto emissivity yog 1. Nws yuav tsum tau taw qhia tias tsis muaj tiag tiag lub cev dub nyob rau hauv cov xwm, tab sis nyob rau hauv thiaj li yuav qhia kom meej thiab tau txais. kev faib tawm ntawm cov hluav taws xob infrared, ib qho qauv tsim nyog yuav tsum tau xaiv hauv kev tshawb fawb theoretical. Qhov no yog qhov quantized oscillator qauv ntawm lub cev kab noj hniav hluav taws xob npaj los ntawm Jintai Keyi, yog li deriving Txoj cai ntawm dub lub cev hluav taws xob ntawm Jintai Keyi, uas yog, lub cev dub spectral radiance qhia nyob rau hauv wavelength, yog qhov pib ntawm tag nrho cov infrared hluav taws xob theories, yog li ntawd. nws yog hu ua txoj cai dub lub cev hluav taws xob.
Kev cuam tshuam ntawm tus pas ntsuas kub qhov khoom emissivity ntawm hluav taws xob ntsuas kub:
Yuav luag txhua yam khoom tiag tiag uas muaj nyob hauv qhov tsis yog lub cev dub. Tus nqi hluav taws xob ntawm tag nrho cov khoom tiag tiag tsis yog nyob ntawm qhov hluav taws xob wavelength thiab qhov kub thiab txias ntawm cov khoom, tab sis kuj yog nyob ntawm cov khoom xws li hom khoom, kev npaj, txheej txheem thermal, lub xeev saum npoo thiab ib puag ncig ntawm cov khoom. Yog li ntawd, txhawm rau ua kom txoj cai dub lub cev hluav taws xob siv tau rau txhua yam khoom tiag, ib qho kev faib ua feem cuam tshuam nrog rau cov khoom siv thiab lub xeev saum npoo yuav tsum tau qhia, uas yog, emissivity. Qhov coefficient no txhais tau hais tias kaw qhov hluav taws xob hluav taws xob ntawm ib qho khoom tiag tiag rau lub cev hluav taws xob, thiab nws tus nqi yog nruab nrab ntawm xoom thiab tus nqi tsawg dua 1. Raws li txoj cai hluav taws xob, tsuav koj paub qhov emissivity ntawm cov khoom, koj tuaj yeem paub. infrared radiation yam ntxwv ntawm tej yam khoom.
Cov yam tseem ceeb uas cuam tshuam rau emissivity ntawm infrared ntsuas kub yog:
Khoom hom, nto roughness, lub cev thiab tshuaj qauv thiab cov khoom thickness, thiab lwm yam.
Thaum siv lub ntsuas hluav taws xob hluav taws xob infrared los ntsuas qhov ntsuas kub ntawm lub hom phiaj, tus nqi ntawm cov hluav taws xob infrared ntawm lub hom phiaj nyob rau hauv nws cov qhab ntau yuav tsum tau ntsuas ua ntej, thiab tom qab ntawd qhov ntsuas kub ntawm lub hom phiaj ntsuas yog xam los ntawm tus pas ntsuas kub. Ib tus pas ntsuas kub ib leeg yog proportional rau tus nqi hluav taws xob nyob rau hauv lub band: ib tug ob-xim ntsuas kub yog proportional rau qhov ratio ntawm tus nqi hluav taws xob nyob rau hauv ob band.
Tus pas ntsuas kub infrared yuav tsum xaiv qhov system infrared kom raug:
Infrared tus pas ntsuas kub muaj cov khoom siv kho qhov muag, photoelectric detector, teeb liab amplifier, teeb liab ua, tso zis tso zis thiab lwm qhov chaw. Lub tshuab kho qhov muag sib sau ua ke lub hom phiaj infrared hluav taws xob hluav taws xob nyob rau 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 kho raws li kev kho sab hauv algorithm ntawm qhov ntsuas thiab lub hom phiaj emissivity.
