Txhua yam khoom tso tawm infrared zog (kub) raws li lawv qhov kub thiab txias.Lub zog infrared tawm los ntawm ib qho khoom hu ua nws lub teeb liab thermal.Feem ntau, qhov kub tshaj qhov khoom yog, qhov hluav taws xob ntau dua nws tawm.Thermal imager (tseem hu ua thermal imager) yog qhov tseem ceeb ntawm thermal sensor, uas tuaj yeem kuaj xyuas qhov sib txawv me me.Lub cuab yeej sau cov hluav taws xob infrared los ntawm cov khoom hauv qhov chaw thiab tsim cov duab hluav taws xob raws li cov ntaub ntawv hais txog qhov kub thiab txias sib txawv.Txij li cov khoom tsis tshua muaj qhov kub thiab txias tib yam li lwm yam khoom nyob ib puag ncig lawv, lawv tuaj yeem kuaj tau los ntawm thermal imager, thiab lawv yuav pom tseeb hauv cov duab thermal.
Cov duab cua sov feem ntau yog grey hauv qhov xwm txheej: cov khoom dub yog txias, cov khoom dawb yog kub, thiab qhov tob ntawm grey qhia qhov txawv ntawm ob.Txawm li cas los xij, qee qhov thermal imagers ntxiv xim rau cov duab los pab cov neeg siv txheeb xyuas cov khoom ntawm qhov kub sib txawv.
Dab tsi yog thermal imaging?
Infrared thermal imager tuaj yeem hloov cov cua sov (piv txwv li lub zog hluav taws xob) rau hauv lub teeb pom kev, txhawm rau txheeb xyuas qhov chaw ib puag ncig.Qhov no ua rau lawv muaj ntau yam.Cov khoom siv roj ntsha thiab cov tshuab ua kom muaj cua sov thiab tuaj yeem pom txawm nyob hauv qhov tsaus ntuj.Cov duab thermal no yog qhov tseeb heev thiab ua haujlwm zoo nrog tsuas yog me me ntawm cov cua sov.
Cov duab thermal ua haujlwm li cas?
Lub teeb pom kev zoo yog qhov tseem ceeb heev rau tib neeg thiab lwm yam kab mob, tab sis nws tsuas yog ib feem me me ntawm electromagnetic spectrum.Infrared hluav taws xob tsim los ntawm tshav kub occupies ntau "chaw" nyob rau hauv lub spectrum.Infrared thermal imager ntes thiab ntsuas qhov kev cuam tshuam ntawm absorbed, reflected thiab qee zaum kis tau cua sov.
Cov theem ntawm thermal tawg tawm los ntawm ib yam khoom yog hu ua nws cov teeb liab thermal.Qhov kub tshaj qhov muab khoom yog, qhov ntau nws yuav tawg mus rau hauv ib puag ncig.Lub thermal imager tuaj yeem paub qhov txawv ntawm qhov chaw tshav kub thiab qhov sib txawv me me thermal tawg.Nws muab cov ntaub ntawv no tso rau hauv ib daim ntawv qhia "kub kub" kom paub qhov txawv ntawm cov cua sov.
Dab tsi yog kev siv thermal imaging?
Keeb xeeb yog siv rau kev tshawb nrhiav hmo ntuj thiab kev sib ntaus sib tua.Txij thaum ntawd los, lawv tau raug txhim kho kom siv tau los ntawm cov neeg tua hluav taws, cov hluav taws xob, cov tub ceev xwm thiab pab pawg cawm hauv thaj chaw puas tsuaj.Lawv kuj tau siv dav hauv kev tshuaj xyuas lub tsev, tu thiab kho kom zoo.
Yuav ua li cas kom paub qhov thermal imaging?
Thermal imaging yuav ua tau ib tug compact thiab zoo technology.Qhov yooj yim thermal imager tuaj yeem ntsuas qhov kub ntawm qhov chaw nruab nrab ntawm cov plaub hau.Cov txheej txheem ntau dua muab ntau cov ntsiab lus sib piv, yog li cov neeg siv tuaj yeem txheeb xyuas ib puag ncig.Lub thermal duab palette sib txawv heev, los ntawm ib tug monochrome palette mus rau ib tug tiav "pseudo xim" palette.
Koj yuav tsum nrhiav dab tsi hauv cov khoom siv thermal imaging?
Tshwj xeeb, koj qhov kev xav tau rau lub thermal imager nyob ntawm ib puag ncig koj siv.Txawm li cas los xij, ob qhov chaw yog qhov tseem ceeb ntawm qhov zoo sib txawv ntawm cov duab thermal: kev daws teeb meem thiab thermal rhiab heev.
Zoo li ntau lwm yam kev daws teeb meem, kev daws teeb meem piav qhia tag nrho cov pixels - piv txwv li, kev daws teeb meem ntawm 160 × 120 muaj 19200 pixels.Txhua tus pixel muaj nws cov ntaub ntawv thermal, yog li qhov kev daws teeb meem loj tuaj yeem tsim cov duab meej dua.
Thermal rhiab heev yog qhov sib txawv qhov pib uas tuaj yeem kuaj pom los ntawm tus duab.Piv txwv li, yog tias qhov rhiab heev ntawm lub cuab yeej yog 0.01 °, cov khoom uas muaj qhov sib txawv ntawm qhov kub ntawm ib feem pua ntawm cov khoom tuaj yeem paub qhov txawv.Qhov tsawg kawg nkaus thiab qhov kub siab tshaj plaws kuj tseem ceeb heev.
Thermal imagers muaj qee qhov kev txwv yooj yim: piv txwv li, lawv tsis tuaj yeem dhau los ntawm iav vim yog cov khoom siv ntawm cov khoom siv.Lawv tseem tuaj yeem pom tab sis tsis tuaj yeem nkag mus rau phab ntsa.Txawm li cas los xij, thermal imaging tau ua pov thawj muaj txiaj ntsig hauv ntau daim ntawv thov.
