Nayiphi na into eneqondo lobushushu elingaphezulu kuka-zero ngokupheleleyo isasaza amandla kwindawo engaphandle ngendlela yokukhanya kwe-infrared. Itekhnoloji yoluvo olusebenzisa imitha ye-infrared ukulinganisa ubungakanani bomzimba obufanelekileyo bubizwa ngokuba yitekhnoloji ye-infrared sensing.
Itekhnoloji ye-infrared sensor yenye yezona teknoloji zikhula ngokukhawuleza kule minyaka yamva nje, i-sensor ye-infrared isetyenziswe ngokubanzi kwi-aerospace, i-astronomy, i-meteorology, i-meteorology, umkhosi, i-industrial kunye ne-civil kunye namanye amasimi, idlala indima ebalulekileyo engenakulinganiswa. I-infrared, eneneni, luhlobo lwamaza ombane wombane, ubude bayo bobude bumalunga ne-0.78m ~ 1000m spectrum uluhlu, kuba ibekwe ekukhanyeni okubonakalayo ngaphandle kwesibane esibomvu, esibizwa ngokuba yi-infrared. Nayiphi na into eneqondo lobushushu elingaphezulu kuka-zero ngokupheleleyo isasaza amandla kwindawo engaphandle ngendlela yokukhanya kwe-infrared. Itekhnoloji yoluvo olusebenzisa imitha ye-infrared ukulinganisa ubungakanani bomzimba obufanelekileyo bubizwa ngokuba yitekhnoloji ye-infrared sensing.
I-sensor ye-infrared ye-Photonic luhlobo lwenzwa esebenza ngokusebenzisa umphumo we-photon we-radiation ye-infrared. Into ebizwa ngokuba yi-photon effect ibhekisela kwinto yokuba xa kukho isiganeko se-infrared kwezinye izinto ze-semiconductor, ukuhamba kwe-photon kwi-radiation ye-infrared idibanisa kunye nee-electron kwi-semiconductor material, ukuguqula imeko yamandla e-electrons, okukhokelela kwizinto ezahlukeneyo zombane. Ngokulinganisa utshintsho kwiipropati ze-elektroniki zezixhobo ze-semiconductor, unokwazi amandla emitha ye-infrared ehambelanayo. Iindidi eziphambili ze-photon detector ziyi-photodetector yangaphakathi, i-photodetector yangaphandle, i-carrier carrier detector, i-QWIP quantum well detector njalo njalo. Iifoto zangaphakathi zahlulwe ngakumbi ngohlobo lwe-photoconductive, uhlobo oluvelisa i-photovolt kunye nohlobo lwe-photomagnetoelectric. Iimpawu eziphambili ze-photon detector zinovakalelo oluphezulu, isantya sokuphendula ngokukhawuleza, kunye nesantya esiphezulu sokuphendula, kodwa ukungalunganga kukuba ibhendi yokufumanisa imxinwa, kwaye isebenza ngokubanzi kumaqondo obushushu aphantsi (ukwenzela ukugcina ubuntununtunu obuphezulu, initrogen engamanzi okanye i-thermoelectric. ifriji isoloko isetyenziselwa ukupholisa i-photon detector kwiqondo lokushisa eliphantsi lokusebenza).
Isixhobo sokuhlalutya icandelo elisekelwe kwi-teknoloji ye-infrared spectrum ineempawu eziluhlaza, ezikhawulezayo, ezingonakalisi kunye ne-intanethi, kwaye yenye yophuhliso olukhawulezayo lweteknoloji yokuhlaziya iteknoloji kwintsimi ye-chemistry yohlalutyo. Iimolekyuli ezininzi zerhasi ezenziwe nge-asymmetric diatom kunye ne-polyatom zineebhanti zokufunxa ezihambelanayo kwibhendi yemitha ye-infrared, kwaye ubude be-wavelength kunye namandla okufunxa amabhanti okufunxa ahlukile ngenxa yeemolekyuli ezahlukeneyo eziqulethwe kwizinto ezilinganisiweyo. Ngokutsho kokusasazwa kweebhanti zokufunxa iimolekyuli ezahlukeneyo zegesi kunye namandla okufunxa, ukubunjwa kunye nomxholo weamolekyu zegesi kwinto elinganisiweyo inokuchongwa. Umhlalutyi werhasi ye-infrared isetyenziselwa ukukhanyisa umlinganiselo ophakathi kunye nokukhanya kwe-infrared, kwaye ngokuhambelana neempawu zokufunxa kwe-infrared kwiimidiya ezahlukeneyo ze-molekyuli, usebenzisa iimpawu ze-infrared zokufunxa igesi, ngokuhlalutya okubonakalayo ukufezekisa ukubunjwa kwegesi okanye uhlalutyo lokuxinana.
I-spectrum yokuxilonga ye-hydroxyl, amanzi, i-carbonate, i-Al-OH, i-Mg-OH, i-Fe-OH kunye nezinye iibhondi ze-molecular inokufumaneka nge-infrared irradiation yento ekujoliswe kuyo, kwaye ke indawo ye-wavelength, ubunzulu kunye nobubanzi be-spectrum ingaba kulinganiswe kwaye kuhlalutywe ukufumana iintlobo zayo, amacandelo kunye nomlinganiselo wezinto ezinkulu zetsimbi. Ngaloo ndlela, uhlalutyo lokubunjwa kweendaba eziqinileyo zinokufezekiswa.
