I-Infrared: Ukwembula Izimfihlo Zamagagasi Angabonakali
I-infrared, evame ukubizwa ngokuthi i-far-infrared, uhlobo lwemisebe kagesi enobude be-wavelength obude kunokukhanya okubonakalayo kodwa obufushane kunamagagasi omsakazo. Igama elithi "infrared" livela kwelesiLatini elithi "infra," elisho "ngaphansi," okubonisa ukuthi i-infrared inamaza angaphansi kokukhanya okubomvu okubonakala ngeso lomuntu. Nakuba ingabonakali, i-infrared idlala indima ebalulekile ezicini eziningi zokuphila kwanamuhla kanye nobuchwepheshe.
Umlando Wokutholwa Kwe-Infrared
Ukutholakala kwemisebe ye-infrared kwaqala ngokuhlolwa kwesayensi okwenziwa yisazi sezinkanyezi uWilliam Herschel ngo-1800. UHerschel, ezama ukulinganisa izinga lokushisa lemibala ehlukene yokukhanya ku-spectrum ebonakalayo, wasebenzisa i-prism yengilazi ukuhlukanisa ukukhanya kwelanga kube umbala wayo wemibala. Ngokubeka ama-thermometer ezingxenyeni ezahlukene ze-spectrum, wathola ukuthi izinga lokushisa eliphakeme kakhulu lalingaphezu kokukhanya okubomvu okubonakalayo. Kulokhu, uHerschel waphetha ngokuthi kwakukhona uhlobo olungabonakali lwemisebe esilwazi manje ngokuthi imisebe ye-infrared.
Izici ze-Infrared
I-infrared isukela kububanzi be-wavelength kusukela cishe kuma-nanometer angu-700 (nm) kuya ku-1 millimeter (mm). I-spectrum ye-infrared ngokwayo ihlukaniswe ngezifunda eziningana: eduze kwe-infrared (0,7–1,3 µm), i-mid-infrared (1,3–3 µm), kanye ne-far infrared (3 µm–1 mm).
I-Near-infrared inezici ezifana nokukhanya okubonakalayo futhi ivame ukusetshenziswa ekuxhumaneni nge-fiber-optic. I-Mid-infrared isetshenziswa ezinhlelweni ezifana ne-spectroscopy kanye ne-thermography, kuyilapho i-far-infrared ivame ukusetshenziswa ezinzwa zokushisa kanye nokutholwa kokushisa.
Izicelo Zobuchwepheshe Be-Infrared
1. Ukuxhumana
I-infrared idlala indima ebalulekile kubuchwepheshe bezokuxhumana, ikakhulukazi ezinhlelweni zokulawula kude. Izilawuli ezikude, njengalezo zamathelevishini, zisebenzisa amasignali e-infrared ukudlulisa imiyalo esuka kulawulo olukude iye kumadivayisi kagesi. I-infrared isetshenziswa futhi kubuchwepheshe bezokuxhumana obungenantambo bebanga elifushane, njenge-IrDA (Infrared Data Association), evumela ukudluliswa kwedatha phakathi kwamadivayisi afana namakhompyutha namaphrinta ngaphandle kwezintambo.
2. Ukuzwa Okukude Namasathelayithi
Emkhakheni wokubona kude, i-infrared iwusizo kakhulu ekubhekeni ubuso boMhlaba usemkhathini. Amasathelayithi afakwe izinzwa ze-infrared angalinganisa izinga lokushisa lobuso boMhlaba, aqaphe izinguquko zemvelo, abone imililo yamahlathi, futhi aqaphele isimo sezulu.
3. Ubuchwepheshe Bezokwelapha
I-infrared nayo inezisetshenziswa ezweni lezokwelapha. Isibonelo, i-infrared thermography isetshenziselwa ukuthola ukushintshashintsha kwezinga lokushisa lomzimba okungase kubonise ukutheleleka noma ukuvuvukala. I-infrared isetshenziswa nasezinqubweni zokuhlinzwa nge-laser, lapho ukukhanya kwe-infrared kusiza khona ukunciphisa noma ukubhubhisa izicubu ezinobungozi ngaphandle kokulimaza izicubu ezinempilo ezizungezile.
4. Umbono Wasebusuku
Ubuchwepheshe bokubona ebusuku busebenzisa ne-infrared. Izibuko zokubona ebusuku zisebenza ngokukhulisa ukukhanya kwe-infrared, okuvame ukuba khona nxazonke zethu kodwa okungabonakali. Lobu buchwepheshe buvumela izinto nabantu ukuthi babonakale ngokucacile ezimweni ezimnyama.
5. Imboni kanye Nezimoto
Embonini, amakhamera okushisa e-infrared asetshenziswa ukuhlola ukushisa ngokweqile emishinini noma ekufakweni kukagesi, okungase kubonise inkinga. Emkhakheni wezimoto, izinzwa zokupaka zisebenzisa i-infrared ukuthola izithiyo ezizungeze izimoto, okwenza kube lula ngabashayeli ukupaka.
Izinzuzo kanye nezinzuzo ze-Infrared
Enye yezinzuzo eziyinhloko ze-infrared yikhono layo lokubona ukushisa. Zonke izinto ezinezinga lokushisa elingaphezu kwe-absolute zero (0 Kelvin) zikhipha imisebe ye-infrared. Ngakho-ke, i-infrared isebenza kahle kakhulu ezinhlelweni ezidinga ukutholwa kokushisa, njenge-thermography kanye nezinzwa zokubona ebusuku.
Enye inzuzo ukutholakala kabanzi, ukungabizi, kanye nokulula kokusebenzisa ubuchwepheshe be-infrared. Ubuchwepheshe be-infrared sekuyisikhathi eside busetshenziswa kumadivayisi avamile njengezilawuli ezikude, amakhamera okuphepha, kanye nezinzwa zezimoto, okwenza kube yinto evamile futhi ethembekile.
Izinselele kanye nokulinganiselwa kwe-Infrared
Naphezu kwezinzuzo zayo ezibanzi, ubuchwepheshe be-infrared bunezinselele zayo. Enye yemikhawulo eyinhloko ye-infrared ukungakwazi kwayo ukungena ezintweni eziqinile. Isibonelo, amasignali e-infrared awakwazi ukungena ezindongeni noma ensimbini, okunciphisa ububanzi bayo kanye nokusetshenziswa kwayo ekuxhumaneni okungenantambo okude.
I-infrared nayo isengozini yokuphazamiseka okuvela kweminye imithombo yokushisa. Ezindaweni ezishisa kakhulu, njengasembonini yensimbi, ukunemba kokutholwa kwe-infrared kungonakalisa. Ngaphezu kwalokho, ukusebenza kwe-infrared kungathinteka yizimo zezulu ezifana nemvula noma inkungu ejiyile, okungavimbela ukudluliswa kwesignali ye-infrared.
Ikusasa Lobuchwepheshe Be-Infrared
Njengoba kunezinhlelo zokusebenza ezahlukahlukene esezivele zithuthukisiwe, i-infrared inamathuba amahle esikhathi esizayo. Ngokuthuthuka kwezobuchwepheshe okusheshayo, izinhlelo zokusebenza ze-infrared kulindeleke ukuthi zisabalale futhi zibe yinkimbinkimbi ngokwengeziwe.
Ezweni lezokwelapha, ucwaningo luyaqhubeka nokuthuthukisa amasu okuxilonga aphephile futhi angangeni kakhulu kusetshenziswa ubuchwepheshe be-infrared. Njengoba ubuchwepheshe bezokuxhumana buthuthuka, izinhlelo zokusebenza ze-infrared ekuphepheni nasekudlulisweni kwedatha nazo zizokhula.
Ekugcineni, i-infrared iyingxenye ye-spectrum kagesi enezindlela eziningi zokusebenzisa. Kusukela ekhonweni layo lokubona ukushisa kuya endimeni yayo kwezobuchwepheshe bezokuxhumana, i-infrared isibe yinto ebalulekile ekuthuthukisweni kwezobuchwepheshe besimanje. Ngocwaningo oluqhubekayo kanye nokusungula izinto ezintsha, akunakuphikwa ukuthi ikusasa lobuchwepheshe be-infrared lizokhanya kakhulu—ngisho noma lihlala lingabonakali.
