Puas muaj peev xwm infrared tus ntsuas kub ntsuas lub cev txias?
Xyoo 1672, nws tau pom tias lub hnub ci (dawb teeb (thiab Newton xaus lus tias Monochromatic lub teeb tau yooj yim dua cov xwm dua li lub teeb dawb. Los ntawm kev siv lub nqaj splitter, hnub ci (lub teeb dawb) tuaj yeem decposed hluav taws xob thaum kawm ntau yam xim ntawm lub teeb los ntawm lub qhov thermal. Nws txhob txwm muab lub qhov rais ntawm lub qhov rais tsaus nti nrog cov laug cam thaum mus kawm qhov kub ntawm ntau lub teeb ntawm lub rooj sib npaug nrog lub nqaj splitter sab hauv. Thaum lub hnub ci dhau los ntawm kev ua yeeb yam, nws yog decomposed rau hauv cov neeg ntsuas kub uas muaj cov xim kub hauv cov xim sib txawv ntawm cov xim sib txawv. Txhawm rau piv nrog qhov ntsuas kub ambient siv ntau qhov ntsuas kub tso rau ze rau cov xim teeb cand rau ntsuas qhov ntsuas kub ntawm qhov kub. Thaum lub sij hawm sim, nws tau tshawb pom qhov xwm txheej txawv txawv: Tus ntsuas kub tau tso sab nraum lub teeb liab tau nyeem dua li lwm qhov kub thiab txias tshaj li lwm qhov kub. Tom qab cov kev sim ua dua, qhov no thiaj li hu ua kev kub kub nrog ntau dua kub yog ib txwm nyob sab nraum lub teeb liab ntawm ntug kev teeb lub teeb. Yog li nws tshaj tawm tias ntxiv rau pom lub teeb, muaj lwm yam hluav taws xob tawm los ntawm lub hnub uas pom tsis tau rau tib neeg lub qhov muag, uas nyob sab nraud lub teeb liab thiab yog hu ua infrared. Qhov hluav taws xob hluav taws xob infrared yog yoj hluav taws xob nrog cov tib yam uas yog xov tooj cua vuag thiab pom lub teeb. Qhov kev tshawb pom ntawm cov hluav taws xob hluav taws xob yog ib qho uas tau ua rau tib neeg kev nkag siab txog xwm, qhib kev tshawb fawb tshiab thiab dav, thiab kev txhim kho cov thev naus laus zis infrared.
Lub wavelength ntawm infrared hluav taws xob ranges ranges los ntawm 0. 76 rau 100 μ-infrared, thiab heev-infrared. Nws txoj haujlwm nyob rau hauv lub spectrum nruam ntawm electromagnetic vuag yog nyob rau hauv thaj av ntawm xov tooj cua vuag thiab pom lub teeb. Kev ntsuas hluav taws xob infrared yog cov dav dav hluav taws xob hluav taws xob hluav taws xob uas muaj nyob hauv qhov. Nws yog ua raws cov lus tsa suab thiab atoms ntawm ib qho khoom hauv ib puag ncig pa, tas li radiating thermal infrared zog. Qhov ntau dua cov lus tsa suab thiab atoms, qhov ntau dua lub zog radiated, thiab vice versia, thiab lwm yam me dua lub zog hluav taws xob.
Cov khoom nrog kub saum toj no abscute xoom yuav emit infrared hluav taws xob vim lawv cov lus tsa suab molecular. Tom qab hloov lub zog hluav taws xob ci ntsa iab los ntawm cov khoom siv hluav taws xob los ntawm cov ntsuas hluav taws xob tuaj yeem sim ua kom pom qhov sib luag ntawm qhov chaw ntawm qhov chaw ntawm qhov chaw scanned ib-rau-ib. Tom qab ua los ntawm lub tshuab hluav taws xob, nws kis tau rau cov zaub screen kom tau txais cov duab thermal sib xws rau cov khoom tawg ntawm cov khoom. Los ntawm kev siv cov qauv no, nws muaj peev xwm ua tiav kom ua tiav cov chaw taws teeb ntsuas thiab ntsuas ntsuas ntawm lub hom phiaj, thiab ntsuas thiab txiav txim rau nws.
