Cov ntsuas kub ruaj khov feem ntau poob rau hauv cov pawg hauv qab no:

Cov ntsuas kub ruaj khov feem ntau poob rau hauv cov pawg hauv qab no:

① Broadband tus pas ntsuas kub, los yog broadband tus pas ntsuas kub, nws cov lus teb spectral yog txwv los ntawm qhov kho qhov muag. Nws yog tsuas yog siv los ntsuas qhov kub thiab txias thiab nruab nrog lub ntsuas ntsuas nrog cov lus teb dav dav.

② Xaiv lub ntsuas kub ntsuas. Nws cov lus teb wavelength yog txwv los ntawm cov lim dej kho qhov muag. Cov kab lus teb ntawm tus ntes tuaj yeem xaiv tau raws li qhov xav tau ntawm daim ntawv thov.

③ Shortwave tus pas ntsuas kub tuaj yeem txo qhov ntsuas qhov yuam kev thaum lub emissivity hloov. Cov nthwv dej luv luv hais ntawm no yog cov txheeb ze, nws tuaj yeem yog lub wavelength ntawm 0.6μm ntawm qhov kub ntawm 1500K, lossis lub wavelength ntawm 3μm ntawm qhov kub ntawm 300K.

④ Colorimetric tus pas ntsuas kub, tseem hu ua ob-xim ntsuas kub, muaj qhov ntsuas tau zoo dua thaum siv hauv "qhov chaw qias neeg heev".

Thaum xaiv tus pas ntsuas kub, ntxiv rau qhov yuav tsum tau muaj qhov kub thiab txias, ob qhov ntsuas ntawm tus pas ntsuas kub, "qhov kub hloov feem pua" thiab "paj pauv hloov pauv", kuj tseem ceeb heev rau kev xaiv tus pas ntsuas kub kom raug:

① Qhov feem pua ​​​​ntawm qhov ntsuas kub hloov pauv ntawm tus pas ntsuas kub yog hais txog qhov kev hloov pauv ntawm cov khoom tsim tawm vim qhov kub hloov pauv. Rau cov ntsuas kub infrared, qhov ntsuas kub ntau dua qhov feem pua, nws qhov rhiab heev.

② Qhov feem pua ​​​​ntawm cov hluav taws xob hloov pauv yog hais txog qhov kev hloov pauv ntawm cov khoom siv hluav taws xob thaum cov hluav taws xob hluav taws xob ntawm qhov ntsuas lub hom phiaj hloov. Txij li thaum lub sij hawm steel dov txheej txheem, lub emissivity ntawm cov hlau phaj hloov random nyob rau hauv ib tug tej yam ntau yam ntawm ib tug tej yam wavelength thiab kub, qhov kev hloov nyob rau hauv tus pas ntsuas kub tso zis nqi tshwm sim los ntawm kev hloov nyob rau hauv lub emissivity tsis yog qhov tseeb kub hloov ntawm lub hom phiaj. Yog li ntawd, nws tseem yuav tsum tau kho qhov hluav taws xob hloov pauv feem pua.
