Qhov ntsuas hluav taws xob infrared yuav tsum raug xaiv los txiav txim siab qhov kev daws teeb meem kho qhov muag
Kev daws teeb meem kho qhov muag yog txiav txim siab los ntawm D rau S, uas yog qhov sib piv ntawm tus pas ntsuas kub thiab lub hom phiaj mus rau txoj kab no yog qhov chaw ntsuas. Yog hais tias tus ntsuas kub yuav tsum muab ntsia dav deb ntawm lub hom phiaj vim ib puag ncig cov kev mob thiab xav tau ntsuas cov ntsuas kub me, qhov kev daws teeb meem zoo kho qhov muag. Qhov siab dua qhov kev daws teeb meem zoo dua, piv txwv li nce D: S piv, cov nqi siab dua tus ntsuas kub.
Txheeb xyuas wavelength ntau yam:
Lub Emissivity Emissivity thiab cov khoom saum npoo ntawm cov khoom siv hauv lub hom phiaj txiav txim siab qhov kev teb zoo nkauj lossis yoj ntawm tus pas ntsuas kub. Txog kev xav txog cov ntaub ntawv alloy, muaj qhov qis lossis sib txawv lossis sib txawv. Hauv cov chaw kub-thaj chaw, cov wavelength rau kev ntsuas cov khoom siv hlau yog ze li {. {}} Μ m yoj. Lwm qhov kub thiab txias thiab txias cov nthwv cua ntawm 1.6 μ m, 2.2 μ m, thiab 3.9 μ m. Vim qee cov ntaub ntawv tau pob tshab rau qee lub zog, lub zog tshwj xeeb tuaj yeem xaiv cov khoom siv no, thiab cov wavel tshwj xeeb yuav tsum tau xaiv rau cov ntaub ntawv no. Yog hais tias ntsuas ntsuas qhov kub ntawm lub khob, wavelengths ntawm 1 {17} μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ m (2.2 μ) yuav tsum tau xaiv los ntawm) Ntsuas qhov kub hauv lub khob uas siv lub wavelength ntawm 5. {{}} Μ m; Nws raug nquahu kom siv lub nthwv dej ntawm 8-14 μ m rau ntsuas cov chaw qis; Piv txwv li, thaum ntsuas Polyethylene yas zaj duab xis, nthwv dej ntawm 3.43 μ m lossis 7.9 μ m siv. Xaiv wavelengths ntawm {25}} μ m rau thicknesses tshaj li {}}. 4mm; 4mm; 4mm; Piv txwv li, CO2 nyob rau hauv cov nplaim taws tau ntsuas siv lub ntsej muag nqaim ntawm 4. 3}}.}}}.}}}}.
Tus ntsuas ntsuas kub infrared yuav tsum tau xaiv kom raug los txiav txim lub sijhawm teb:
Lub sijhawm teb sawv cev rau cov tshuaj tiv thaiv ceev ntawm tus pas ntsuas kub online kom hloov pauv qhov ntsuas kub, txhais tau tias yog lub sijhawm yuav tsum tau mus txog 95% lub zog ntawm kev nyeem ntawv kawg. Nws muaj feem xyuam rau lub sijhawm tas li ntawm cov photodetector, teeb liab kev ua Circuital, thiab Display System. Lub sijhawm teb ntawm tus pas ntsuas kub tshiab los ntawm jinkoke ntsuas tuaj yeem ncav cuag 1ms. Qhov no nrawm dua li tiv toj cov kev ntsuas kub. Yog tias lub hom phiaj txav ntawm lub nrawm nrawm lossis thaum ntsuas qhov ntsuas kub sai sai, txwv tsis pub nws yuav txo qis kev ntsuas qhov raug. Txawm li cas los xij, tsis yog txhua daim ntawv thov yuav tsum muaj cov lus teb ceev infrared infrared. Thaum muaj thermal inertia nyob rau hauv ib qho chaw nyob lossis phiaj txheej txheem thermal, lub sijhawm teb ntawm tus pas ntsuas kub tuaj yeem so. Yog li ntawd, kev xaiv ntawm lub sijhawm teb rau lub ntsuas kub infrared yuav tsum tau yoog raws li qhov xwm txheej ntawm lub hom phiaj ntsuas.
