A zamanin bayan annoba, mun yi imanin cewa na'urorin auna zafin jiki na infrared suna da matuƙar muhimmanci kowace rana. A cikin tsarin tafiya, muna buƙatar yin gwajin zafin jiki akai-akai kafin mu isa inda muke. A matsayin ma'aunin zafin jiki tare da adadi mai yawa na na'urori masu auna zafin jiki na infrared, a zahiri, akwai ayyuka da yawa masu mahimmanci. Na gaba, bari mu yi la'akari da na'urar auna zafin jiki ta infrared sosai.
Gabatarwa ga Na'urori Masu auna Infrared
Duk wani abu sama da sifili (-273°C) yana ci gaba da fitar da makamashin infrared zuwa sararin da ke kewaye, a iya cewa. Kuma na'urar firikwensin infrared, tana iya jin kuzarin infrared na abin kuma ta mayar da shi zuwa sassan lantarki. Na'urar firikwensin infrared ta ƙunshi tsarin gani, abubuwan gano abubuwa da kuma da'irar juyawa.
Za a iya raba tsarin gani zuwa nau'in watsawa da nau'in nuni bisa ga tsari daban-daban. Watsawa tana buƙatar sassa biyu, ɗaya mai watsa infrared da ɗayan mai karɓar infrared. A gefe guda kuma, mai haskakawa yana buƙatar firikwensin guda ɗaya kawai don tattara bayanan da ake so.
Ana iya raba sinadarin ganowa zuwa sinadaran gano zafi da kuma sinadaran gano haske na lantarki bisa ga ka'idar aiki. Masu auna zafi su ne masu auna zafi da aka fi amfani da su. Lokacin da aka yi amfani da na'urar auna zafi ta hanyar hasken infrared, zafin jiki yana ƙaruwa, kuma juriya tana canzawa (wannan canjin na iya zama babba ko ƙarami, saboda ana iya raba na'urar auna zafi zuwa na'urar auna zafi mai kyau da na'urar auna zafi mai kyau), wanda za'a iya canza shi zuwa fitowar siginar lantarki ta hanyar da'irar juyawa. Ana amfani da abubuwan gano haske na lantarki a matsayin abubuwan da ke da tasirin haske, galibi ana yin su ne da lead sulfide, lead selenide, indium arsenide, antimony arsenide, mercury cadmium telluride ternary alloy, germanium da silicon doped kayan.
Dangane da nau'ikan na'urori masu sarrafa sigina da kuma juyawa, ana iya raba na'urori masu auna sigina zuwa nau'in analog da na dijital. Da'irar sarrafa sigina ta na'urar auna infrared ta pyroelectric ita ce bututun tasirin filin, yayin da da'irar sarrafa sigina ta na'urar auna infrared ta pyroelectric ta dijital ita ce guntu na dijital.
Ana samun ayyuka da yawa na na'urar firikwensin infrared ta hanyar canza abubuwa daban-daban da haɗuwa da abubuwa uku masu mahimmanci: tsarin gani, abubuwan ganowa da kuma da'irar juyawa. Bari mu kalli wasu wurare inda na'urori masu firikwensin infrared suka yi tasiri.
Amfani da Firikwensin Infrared
1. Gano Iskar Gas
Ka'idar infrared optical firikwensin gas wani nau'i ne da ya dogara da halayen kusan infrared spectral selective absorption na ƙwayoyin gas daban-daban, amfani da yawan iskar gas da alaƙar ƙarfi (Lambert - dokar Lambert Beer) don gano da kuma tantance yawan na'urar gano iskar gas.
Ana iya amfani da na'urori masu auna zafin jiki na infrared don samun taswirar nazarin infrared kamar yadda aka nuna a cikin hoton da ke sama. Kwayoyin da suka ƙunshi ƙwayoyin halitta daban-daban za su sha infrared a ƙarƙashin hasken infrared a mita ɗaya, wanda ke haifar da canje-canje a cikin ƙarfin hasken infrared. Dangane da kololuwar raƙuman ruwa daban-daban, ana iya tantance nau'ikan iskar gas da ke cikin cakuda.
Dangane da matsayin kololuwar sha na infrared guda ɗaya, kawai waɗanne ƙungiyoyi ne ke wanzuwa a cikin kwayar iskar gas za a iya tantancewa. Don tantance nau'in iskar gas daidai, muna buƙatar duba matsayin duk kololuwar sha a yankin tsakiyar infrared na iskar gas, wato, sawun sha na infrared na iskar gas. Tare da bakan infrared, ana iya yin nazarin abubuwan da ke cikin kowace iskar gas a cikin cakuda cikin sauri.
Ana amfani da na'urorin auna iskar gas na infrared sosai a fannin sinadarai na fetur, masana'antar ƙarfe, hakar ma'adinai a yanayin aiki, sa ido kan gurɓatar iska da gano abubuwan da suka shafi rage gurɓatar carbon, noma da sauran masana'antu. A halin yanzu, na'urorin laser na tsakiyar infrared suna da tsada. Ina tsammanin a nan gaba, tare da yawan masana'antu da ke amfani da na'urori masu auna infrared don gano iskar gas, na'urorin auna iskar gas na infrared za su zama mafi kyau da rahusa.
2. Ma'aunin Nisa na Infrared
Na'urar firikwensin infrared wani nau'in na'urar ji, ana amfani da infrared a matsayin hanyar aunawa, kewayon aunawa mai faɗi, lokacin amsawa na ɗan gajeren lokaci, wanda galibi ana amfani da shi a fannin kimiyya da fasaha ta zamani, tsaron ƙasa da filayen masana'antu da noma.
Na'urar firikwensin infrared tana da diodes guda biyu na siginar infrared mai watsawa da karɓa, tana amfani da na'urar firikwensin infrared don fitar da hasken infrared, tana samar da tsarin haske bayan haskakawa ga abu, tana nunawa ga na'urar firikwensin bayan karɓar siginar, sannan kuma tana amfani da sarrafa hoton CCD mai karɓar watsawa da karɓar bayanan bambancin lokaci.
