一, feem ntau siv cov txheej txheem sib faib ntawm infrared

Ib qho feem ntau siv sub-of-faib cov txheej txheem ntawm infrared (ir) hluav taws xob yog raws li lub yoj yoj. IR Spectrum feem ntau muab faib ua cov cheeb tsam hauv qab no:

Ze-infrared (NIR):Thaj av no muaj kwv yees li ntawm 700 nanometers (NM) rau 1.4 micrometers (μm) hauv nthwv dej. NIR hluav taws xob feem ntau yog siv nyob rau hauv cov chaw taws teeb, cov xov tooj kev siv hluav taws xob muaj fiber ntau vim yog cov khoom poob qis hauv cov iav Sio2 (silica) nruab nrab. Cov duab ua kom muaj kev nkag siab txog thaj chaw no ntawm lub spectrum; Piv txwv muaj xws li pom cov khoom siv pom zoo xws li hmo ntuj pom kev goggles. Ze-infrared spectroscopy yog lwm daim ntawv thov.

Luv-wavelength infrrared (swir):Kuj tseem hu ua "Shortwave infrared" lossis "thaj av swir", nws txuas ntxiv los ntawm txog 1.4 μm txog 3 μm. Swir hluav taws xob yog feem ntau siv nyob rau hauv kev teeb meem, kev soj ntsuam xyuas, thiab cov ntawv thov spectroscopys.

Mid-wavelength infrared (Mwir):Lub Mwir cheeb tsam nthuav tawm los ntawm kwv yees li 3 μm txog 8 μm. Qhov ntau no yog nquag ua hauj lwm hauv Thermal kev ua tswv yim, tub rog lub hom phiaj, thiab cov tshuab tshuaj nrhiav pa.

Ntev-wavelength infrared (Lwir):Lub Lwir cheeb tsam npog wavelengths los ntawm ib ncig ntawm 8 μm txog 15 μm. Nws yog feem ntau siv nyob rau hauv kev ua cua sov, tsaus ntuj lub tshuab, thiab tsis sib cuag kub ntsuas kub.

Deb-infrared (fir):Qhov chaw no txuas ntxiv kwv yees li 15 μm rau 1 millimeter (hli) hauv nthwv dej. Fir hluav taws xob hluav taws xob feem ntau siv hauv cov hnub qub, cov chaw taws teeb, thiab tej yam kev siv tshuaj kho mob.

Wavelength muaj ntau daim duab kos duab

NIR and SWIR together is sometimes called “reflected infrared”, whereas MWIR and LWIR is sometimes referred to as “thermal infrared”.

二, kev siv ntawm infrared

Hmo ntuj pom kev

Infrared (ir) plays lub luag haujlwm tseem ceeb nyob rau hauv naan tarchet, enterping kev kuaj pom thiab pom ntawm cov khoom nyob hauv ib puag ncig lub teeb lossis tsaus. Cov Duab Tsaus Ntuj Siv Zog Nruab Nrab Cov cuab yeej siv no siv cov photocathode los hloov cov phij vab, suav nrog IR Photons, rau hauv cov khoom siv hluav taws xob. Cov tshuab hluav taws xob tau nrawm thiab nthuav dav los tsim cov duab pom. Infrared illuminators, uas emit irit irit, feem ntau ua ke rau cov cuab yeej siv hauv kev tsaus ntuj lossis lub teeb qis uas muaj cov huab cua AMADIAT tsis txaus.

Tsawg lub teeb ib puag ncig

Cua sov

Kev ntsuas hluav taws xob infrared tuaj yeem siv rau remotely txiav txim siab qhov ntsuas kub ntawm cov khoom (yog tias lub emissivity yog paub). Qhov no yog lub thermography termography, los yog nyob rau hauv cov ntaub ntawv ntawm cov khoom kub heev hauv NIR lossis pom nws yog ib qho pyrometry. Thermography (thermal kev ntsuam xyuas) feem ntau yog siv nyob rau hauv cov ntaub ntawv tub rog thiab thev naus laus zis tab tom ncav cuag cov tub rog infrared nyob rau hauv cov tsheb uas muaj nqi ntau lawm.

Qhov Kev Siv Thermal Ntsuas

Kev ntsuas hluav taws xob infrared tuaj yeem siv rau remotely txiav txim siab qhov ntsuas kub ntawm cov khoom (yog tias lub emissivity yog paub). Qhov no yog lub thermography termography, los yog nyob rau hauv cov ntaub ntawv ntawm cov khoom kub heev hauv NIR lossis pom nws yog ib qho pyrometry. Thermography (thermal kev ntsuam xyuas) feem ntau yog siv nyob rau hauv cov ntaub ntawv tub rog thiab thev naus laus zis tab tom ncav cuag cov tub rog infrared nyob rau hauv cov tsheb uas muaj nqi ntau lawm.

Thiakogic cov koob yees duab ntes hluav taws xob hauv infromagnetic spectrome (ntxig 9,000 μm) thiab muab cov duab ntawm cov hluav taws xob. Txij li thaum infrared hluav taws xob raug teeb tsa los ntawm txhua cov khoom raws li lawv qhov kub-txoj cai ci ntsa iab, raws li lub cev hluav taws xob hluav taws xob, raws li "pom" ib puag ncig nrog lossis tsis muaj qhov ua kom pom tseeb. Qhov ntau ntawm kev tso tawm hluav taws xob emitiation los ntawm ib qho khoom nce nrog qhov kub thiab txias, yog li thermoror tso cai rau ib qho kom pom kev hloov pauv hauv qhov kub.

Kev Ntsuas Hluav Taws Xob

Ib lub tswv yim zoo yog "daim duab" uas muaj spectrum txuas ntxiv mus txog ntau qhov chaw dav dav ntawm txhua pixel. Qhov kev ntsuas siab yog tau txais qhov tseem ceeb hauv kev siv spectroscopy tshwj xeeb nrog nir, swir, mwir, thiab LWIR ntau qhov chaw. Cov ntawv thov raug suav nrog kev ntsuas roj ntsha, ntxhia, kev tiv thaiv, thiab cov ntsuas kev lag luam.

Qhov Kev Ntsuas Cov Duab

Thermal infrared hyperspectoral yuav ua tau zoo sib xws siv qhov sib txawv uas txhua tus pixel muaj tag nrho cov lwir spectrum. Yog li ntawd, cov neeg paub tseeb ntawm cov khoom tuaj yeem ua tau yam tsis muaj kev xav tau rau lub teeb pom kev sab nraud xws li lub hnub lossis lub hli. Cov koob yees duab zoo li no feem ntau yog thov rau cov kev ntsuas ntsuas gatological, kev soj ntsuam sab nraum zoov thiab UAV daim ntawv thov.

Tso kev sov

Infrared (ir) hluav taws xob tuaj yeem siv los ua cov cua sov ua kom sov nyob hauv ntau yam kev siv. Qhov no feem ntau yog vim yog qhov muaj peev xwm ntawm IR RADIATING los hloov cov khoom cua sov rau cov khoom lossis cov chaw tsis muaj cua sov ib puag ncig puag ncig ib puag ncig. Infrared (ir) hluav taws xob tuaj yeem siv los ua cov cua sov ua kom sov nyob hauv ntau yam kev siv. Qhov no feem ntau yog vim yog qhov muaj peev xwm ntawm IR RADIATING los hloov cov khoom cua sov rau cov khoom lossis cov chaw tsis muaj cua sov ib puag ncig puag ncig ib puag ncig.

Cov khoom cua sov

Kev ntsuas hluav taws xob infrared tau dav siv hauv ntau cov txheej txheem cua sov. Piv txwv li, hauv kev tsim khoom, IR lub teeb txawb lossis cov vaj huam sib luag yog feem ntau ua haujlwm rau cov khoom cua sov, xws li cov yas, lossis pleev xim, lossis ua kom qhuav, lossis sib sau ua ke. IR RADIATIAS tuaj yeem yog qhov tseeb tswj thiab qhia, tso cai rau cov cua sov thiab nrawm nrawm rau hauv qee thaj chaw tshwj xeeb.
