Shay kasta oo heerkulkiisu ka sarreeyo eber buuxa wuxuu tamarta u shidaa hawada sare isagoo adeegsanaya iftiinka infrared-ka. Tiknoolajiyadda dareenka ee adeegsata shucaaca infrared-ka si loo cabbiro tirada jireed ee khuseeya waxaa loo yaqaan tiknoolajiyadda dareenka infrared-ka.
Tiknoolajiyadda dareemayaasha infrared-ka waa mid ka mid ah teknoolojiyada ugu horumarsan sannadihii ugu dambeeyay, dareemayaasha infrared-ka waxaa si weyn loogu isticmaalay hawada sare, xiddigaha, saadaasha hawada, militariga, warshadaha iyo goobaha kale, iyadoo door muhiim ah ka ciyaarta. Infrared-ku, asal ahaan, waa nooc ka mid ah hirarka shucaaca elektromagnetic-ka, masaafada hirarkiisu waa qiyaastii 0.78m ~ 1000m, sababtoo ah waxay ku taal iftiinka muuqda ee ka baxsan iftiinka cas, sidaas darteed waxaa loogu yeeraa infrared. Shay kasta oo heerkulkiisu ka sarreeyo eber buuxa wuxuu tamarta u shidaa booska bannaanka qaab iftiin infrared ah. Tiknoolajiyadda dareenka ee adeegsata shucaaca infrared-ka si loo cabbiro tirada jireed ee khuseeya waxaa loo yaqaan tignoolajiyada dareenka infrared-ka.
Dareemaha infrared-ka ee Photonic waa nooc ka mid ah dareemayaasha ka shaqeeya iyadoo la adeegsanayo saameynta photon-ka ee shucaaca infrared-ka. Waxa loogu yeero saameynta photon-ka waxay tilmaamaysaa marka ay dhacdo dhacdo infrared ah oo ku dhacda qaar ka mid ah walxaha semiconductor-ka, socodka photon-ka ee shucaaca infrared-ka wuxuu la falgalaa elektaroonada ku jira walxaha semiconductor-ka, isagoo beddelaya xaaladda tamarta ee elektaroonada, taasoo keenta ifafaale koronto oo kala duwan. Markaad cabbirto isbeddellada ku yimaada sifooyinka elektaroonigga ah ee walxaha semiconductor-ka, waxaad ogaan kartaa xoogga shucaaca infrared-ka ee u dhigma. Noocyada ugu muhiimsan ee dareemayaasha photon-ka waa sawir-qaade gudaha ah, sawir-qaade dibadda ah, sawir-qaade xor ah, qalabka ceelka quantum ee QWIP iyo wixii la mid ah. Sawir-qaadeyaasha gudaha waxaa loo sii qaybiyaa nooca sawir-qaadista, nooca dhaliya photovolt-ka iyo nooca sawir-qaade koronto. Astaamaha ugu muhiimsan ee qalabka sawir-qaade photon-ka waa xasaasiyad sare, xawaaraha jawaab celinta degdega ah, iyo soo noqnoqoshada jawaab celinta sare, laakiin khasaaraha ayaa ah in xarigga ogaanshaha uu cidhiidhi yahay, guud ahaanna uu ka shaqeeyo heerkul hoose (si loo ilaaliyo xasaasiyadda sare, nitrogen dareere ah ama qaboojiyaha thermoelectric-ka ayaa badanaa loo isticmaalaa in lagu qaboojiyo qalabka sawir-qaade ilaa heerkul shaqo oo hooseeya).
Qalabka falanqaynta qaybaha ee ku salaysan tignoolajiyada muuqaalka infrared-ka wuxuu leeyahay astaamaha cagaarka, dhaqsaha badan, aan burburin iyo khadka tooska ah, waana mid ka mid ah horumarka degdegga ah ee tignoolajiyada falanqaynta ee tignoolajiyada sare ee cilmiga kiimikada falanqaynta. Moleekuleyaasha gaaska badan oo ka kooban diatoms iyo polyatoms aan sinnayn waxay leeyihiin xargaha nuugista ee u dhigma ee ku jira xargaha shucaaca infrared-ka, hirarka iyo xoogga nuugista ee xargaha nuugista way kala duwan yihiin sababtoo ah moleekuleyaasha kala duwan ee ku jira walxaha la cabbiray. Sida laga soo xigtay qaybinta xargaha nuugista ee moleekuleyaasha gaaska kala duwan iyo xoogga nuugista, halabuurka iyo waxa ku jira moleekuleyaasha gaaska ee shayga la cabbiray waa la aqoonsan karaa. Falanqeeyaha gaaska infrared-ka waxaa loo isticmaalaa in lagu iftiimiyo dhexdhexaadka la cabbiray iyadoo la adeegsanayo iftiinka infrared-ka, iyo sida waafaqsan astaamaha nuugista infrared-ka ee warbaahinta kala duwan ee moleekuleyaasha, iyadoo la adeegsanayo astaamaha nuugista infrared-ka ee gaaska, iyada oo loo marayo falanqaynta spectral-ka si loo gaaro halabuurka gaaska ama falanqaynta diiradda.
Noocyada ogaanshaha ee hydroxyl, biyaha, kaarboonat, Al-OH, Mg-OH, Fe-OH iyo isku xidhka kale ee molecular waxaa lagu heli karaa shucaaca infrared-ka ee shayga la beegsanayo, ka dibna booska hirarka, qoto dheerka iyo ballaca spectrum-ka ayaa la cabbiri karaa oo la falanqeyn karaa si loo helo noocyadiisa, qaybaha iyo saamiga walxaha birta ee waaweyn. Sidaas darteed, falanqaynta isku-dhafka ee warbaahinta adag ayaa la xaqiijin karaa.
