Nantoni na enobushushu obungaphezulu kwe-absolute zero ikhupha amandla esibhakabhakeni ngendlela yokukhanya kwe-infrared. Itekhnoloji yokuva esebenzisa imitha ye-infrared ukulinganisa ubungakanani obufanelekileyo bomzimba ibizwa ngokuba yitekhnoloji yokuva ye-infrared.
Itekhnoloji ye-infrared sensor yenye yezona teknoloji ziphuhlisayo ngokukhawuleza kwiminyaka yakutshanje, i-infrared sensor isetyenziswa kakhulu kwiindawo zeenqwelo-moya, i-astronomy, i-meteorology, imikhosi, imboni kunye nemimandla yoluntu kunye neminye imimandla, idlala indima ebalulekileyo engenakutshintshwa. I-infrared, ngokuyintloko, luhlobo lwamaza emitha ye-electromagnetic radiation, uluhlu lwayo lwamaza lumalunga ne-0.78m ~ 1000m spectrum range, kuba ikwindawo yokukhanya okubonakalayo ngaphandle kokukhanya okubomvu, okubizwa ngokuba yi-infrared. Nayiphi na into enobushushu obungaphezulu kwe-absolute zero ikhupha amandla esibhakabhakeni ngendlela yokukhanya kwe-infrared. Itekhnoloji yokuva esebenzisa imitha ye-infrared ukulinganisa ubungakanani obufanelekileyo bomzimba ibizwa ngokuba yitekhnoloji yokuva ye-infrared.
I-Photonic infrared sensor luhlobo lwe-sensor esebenza ngokusebenzisa i-photon effect ye-infrared radiation. I-photon effect ebizwa ngokuba yi-photon effect ibhekisa kwinto yokuba xa kukho isiganeko se-infrared kwezinye izinto ze-semiconductor, ukuhamba kwe-photon kwi-infrared radiation kudibana nee-electron kwi-semiconductor material, nto leyo etshintsha imeko yamandla ee-electron, nto leyo ebangela iziganeko ezahlukeneyo zombane. Ngokulinganisa utshintsho kwiimpawu ze-elektroniki zezinto ze-semiconductor, ungawazi amandla e-infrared radiation ehambelanayo. Iintlobo eziphambili ze-photon detectors yi-internal photodetector, i-external photodetector, i-free carrier detector, i-QWIP quantum well detector njalo njalo. I-internal photodetectors zahlulwe ngakumbi ngohlobo lwe-photoconductive, uhlobo oluvelisa i-photovolt kunye nohlobo lwe-photomagnetoelectric. Iimpawu eziphambili ze-photon detector kukuvakalelwa okuphezulu, isantya sokuphendula ngokukhawuleza, kunye ne-high response frequency, kodwa ingxaki kukuba i-detection band incinci, kwaye ngokubanzi isebenza kumaqondo obushushu aphantsi (ukuze kugcinwe uvakalelo oluphezulu, i-nitrogen engamanzi okanye i-thermoelectric refrigeration idla ngokusetyenziswa ukupholisa i-photon detector ukuya kubushushu obuphantsi bokusebenza).
Isixhobo sohlalutyo lwamacandelo esisekelwe kwitekhnoloji ye-infrared spectrum sineempawu eziluhlaza, ezikhawulezayo, ezingatshabalalisiyo nezikwi-intanethi, kwaye sesinye sezona zinto ziphuhlisa ngokukhawuleza itekhnoloji yohlalutyo yobuchwepheshe obuphezulu kwicandelo lekhemistri yohlalutyo. Iimolekyuli ezininzi zegesi ezenziwe ngee-diatoms ezingafaniyo kunye nee-polyatoms zineebhendi zokufunxa ezifanayo kwibhendi yemitha ye-infrared, kwaye ubude bobude kunye namandla okufunxa eebhendi zokufunxa zahlukile ngenxa yeemolekyuli ezahlukeneyo ezikwizinto ezilinganisiweyo. Ngokwendlela yokusasazwa kweebhendi zokufunxa zeemolekyuli ezahlukeneyo zegesi kunye namandla okufunxa, ukwakheka kunye nomxholo weemolekyuli zegesi kwinto elinganisiweyo kunokuchongwa. I-infrared gas analyzer isetyenziselwa ukukhanyisela i-medium elinganisiweyo ngokukhanya kwe-infrared, kwaye ngokweempawu zokufunxa ze-infrared zemidiya eyahlukeneyo yeemolekyuli, kusetyenziswa iimpawu ze-infrared absorption spectrum zegesi, ngohlalutyo lwe-spectral ukufezekisa uhlalutyo lwe-gas composition okanye concentration.
I-spectrum yokuxilonga ye-hydroxyl, amanzi, i-carbonate, i-Al-OH, i-Mg-OH, i-Fe-OH kunye nezinye iibhondi ze-molecular zinokufunyanwa ngokukhanyiselwa kwe-infrared kwento ekujoliswe kuyo, kwaye emva koko indawo ye-wavelength, ubunzulu kunye nobubanzi be-spectrum zinokulinganiswa kwaye zihlalutywe ukuze kufunyanwe uhlobo lwayo, iinxalenye kunye nomlinganiselo wezinto eziphambili zesinyithi. Ngaloo ndlela, uhlalutyo lokwakheka kwe-solid media lunokufezekiswa.
