Noma iyiphi into enezinga lokushisa elingaphezu kukaziro ophelele ikhipha amandla emkhathini ngendlela yokukhanya kwe-infrared. Ubuchwepheshe bezinzwa obusebenzisa imisebe ye-infrared ukukala amanani aphathekayo aphathekayo bubizwa ngokuthi ubuchwepheshe bokuzwa nge-infrared.
Ubuchwepheshe bezinzwa ze-infrared bungobunye bobuchwepheshe obuthuthuka ngokushesha eminyakeni yamuva nje, inzwa ye-infrared isetshenziswe kabanzi ku-aerospace, i-astronomy, meteorology, ezempi, yezimboni kanye neyomphakathi kanye neminye imikhakha, idlala indima ebalulekile engenakulinganiswa. I-infrared, empeleni, iwuhlobo lwamaza emisebe kagesi, ububanzi bayo be-wavelength bulinganiselwa ku-0.78m ~ 1000m spectrum range, ngoba itholakala ekukhanyeni okubonakalayo ngaphandle kwesibani esibomvu, esiqanjwe kanjalo nge-infrared. Noma iyiphi into enezinga lokushisa elingaphezu kukaziro ophelele ikhipha amandla emkhathini ngendlela yokukhanya kwe-infrared. Ubuchwepheshe bezinzwa obusebenzisa imisebe ye-infrared ukukala amanani aphathekayo aphathekayo bubizwa ngokuthi ubuchwepheshe bokuzwa nge-infrared.
Inzwa ye-Photonic infrared iwuhlobo lwenzwa esebenza ngokusebenzisa umphumela we-photon wemisebe ye-infrared. Okubizwa ngokuthi umphumela we-photon kubhekisela ekutheni uma kunesigameko se-infrared kwezinye izinto ze-semiconductor, ukugeleza kwe-photon emisebeni ye-infrared kusebenzisana nama-electron asendaweni ye-semiconductor, kushintsha isimo samandla sama-electron, okuholela ezimweni ezihlukahlukene zikagesi. Ngokulinganisa izinguquko kuzakhiwo ze-elekthronikhi zezinto ze-semiconductor, ungakwazi ukwazi amandla emisebe ye-infrared ehambisanayo. Izinhlobo eziyinhloko zama-photon detector yi-photodetector yangaphakathi, i-photodetector yangaphandle, i-carrier carrier detector, i-QWIP quantum well detector njalonjalo. Ama-photodetectors angaphakathi aphinde ahlukaniswe abe uhlobo lwe-photoconductive, uhlobo olukhiqiza i-photovolt kanye nohlobo lwe-photomagnetoelectric. Izici eziyinhloko zomtshina we-photon ukuzwela okuphezulu, isivinini sokuphendula okusheshayo, kanye nemvamisa yokuphendula ephezulu, kodwa okubi ukuthi ibhendi yokuthola incane, futhi ngokuvamile isebenza emazingeni okushisa aphansi (ukuze kugcinwe ukuzwela okuphezulu, i-nitrogen ewuketshezi noma i-thermoelectric. isiqandisi sivame ukusetshenziselwa ukupholisa umtshina we-photon ekushiseni okuphansi kokusebenza).
Ithuluzi lokuhlaziya ingxenye elisekelwe kubuchwepheshe be-infrared spectrum linezimpawu zokuluhlaza, okusheshayo, okungabhubhisi kanye ne-inthanethi, futhi ingenye yentuthuko esheshayo yobuchwepheshe bokuhlaziya obusezingeni eliphezulu emkhakheni wekhemistri yokuhlaziya. Ama-molecule amaningi egesi akhiwe ama-diatom a-asymmetric kanye nama-polyatom anamabhande okumunca ahambisanayo ebhandeni lemisebe ye-infrared, futhi ubude begagasi namandla okumunca amabhande okumunca ahlukile ngenxa yama-molecule ahlukene aqukethwe ezintweni ezilinganisiwe. Ngokusatshalaliswa kwamabhande okumuncwa ama-molecule egesi ahlukahlukene namandla okumuncwa, ukwakheka nokuqukethwe kwama-molecule egesi entweni elinganisiwe kungabonakala. I-infrared gas analyzer isetshenziselwa ukukhanyisela okuphakathi nendawo ngokukhanya kwe-infrared, futhi ngokuya nezici zokumuncwa kwe-infrared zemidiya ehlukahlukene yamangqamuzana, kusetshenziswa izici zokumuncwa kwegesi kwe-infrared, ngokuhlaziywa kwe-spectral ukuze kuzuzwe ukwakheka kwegesi noma ukuhlaziya ukugxila.
I-spectrum yokuxilonga ye-hydroxyl, amanzi, i-carbonate, i-Al-OH, i-Mg-OH, i-Fe-OH nezinye izibopho zamangqamuzana zingatholakala ngokushisa kwe-infrared yento ehlosiwe, bese indawo ye-wavelength, ukujula nobubanzi be-spectrum kungaba kulinganiswa futhi kuhlaziywe ukuze kutholwe izinhlobo zayo, izingxenye kanye nesilinganiso sezakhi ezinkulu zensimbi. Ngakho-ke, ukuhlaziya ukwakheka kwemidiya eqinile kungenziwa.
