Zonke izinto zikhipha amandla e-infrared (ukushisa) ngokuya ngokushisa kwazo. Amandla e-infrared akhishwa yinto abizwa ngokuthi isignali yayo yokushisa. Ngokuvamile, lapho into ishisa kakhulu, ikhipha imisebe eminingi. I-Thermal imager (eyaziwa nangokuthi i-thermal imager) empeleni iyinzwa yokushisa, engathola umehluko omncane wokushisa. Idivayisi iqoqa imisebe ye-infrared ezintweni ezisendaweni futhi idale izithombe ze-elekthronikhi ngokusekelwe olwazini mayelana nomehluko wokushisa. Njengoba izinto zingavamile ukuba sezingeni lokushisa elifanayo nezinye izinto ezizungezile, zingatholakala yi-thermal imager, futhi zizobonakala zisobala esithombeni sokushisa.
Izithombe ezishisayo zivame ukuba impunga ngokwemvelo: izinto ezimnyama ziyabanda, izinto ezimhlophe ziyashisa, kanti ukujula kompunga kubonisa umehluko phakathi kwalezi ezimbili. Kodwa-ke, abanye abathwebuli bezithombe ezishisayo banezela umbala esithombeni ukusiza abasebenzisi ukuthi babone izinto emazingeni okushisa ahlukene.
Kuyini ukuthwebula izithombe ezishisayo?
I-infrared thermal imager ingaguqula ukushisa ngempumelelo (okungukuthi amandla okushisa) kube ukukhanya okubonakalayo, ukuze ihlaziye indawo ezungezile. Lokhu kuyenza ibe nezimo eziningi kakhulu. Amadivayisi ezinto eziphilayo kanye nawomshini akhipha ukushisa futhi angabonakala ngisho nasebumnyameni. Lezi zithombe ezishisayo zinembile kakhulu futhi zisebenza kahle ngokushisa okuncane kuphela.
Isebenza kanjani izithombe ezishisayo?
Ukukhanya okubonakalayo kuwusizo kakhulu kubantu nakwezinye izinto eziphilayo, kodwa kuyingxenye encane nje ye-spectrum ye-electromagnetic. Imisebe ye-infrared ekhiqizwa ukushisa ithatha "isikhala" esiningi ku-spectrum. I-infrared thermal imager ibamba futhi ihlole ukusebenzisana kokushisa okumuncwayo, okubonakalayo futhi ngezinye izikhathi okudluliswayo.
Izinga lemisebe yokushisa ekhishwa yinto libizwa ngokuthi isignali yayo yokushisa. Uma into ethile ishisa kakhulu, kulapho izokhipha khona ukukhanya okukhulu endaweni ezungezile. Isithombe se-thermal singahlukanisa phakathi komthombo wokushisa kanye nomehluko omncane wemisebe yokushisa. Sihlanganisa le datha ibe "imephu yokushisa" ephelele ukuze ihlukanise ngezinga lokushisa.
Iyini inzuzo yesithombe sokushisa?
Ekuqaleni zazisetshenziselwa ukuhlola nokulwa ebusuku. Kusukela ngaleso sikhathi, ziye zathuthukiswa ukuze zisetshenziswe ngabacishi bomlilo, ochwepheshe bakagesi, abasebenzi bomthetho kanye namaqembu okutakula ezindaweni zenhlekelele. Zisetshenziswa kabanzi nasekuhlolweni kwezakhiwo, ekunakekelweni nasekuthuthukisweni kwazo.
Ungawenza kanjani umsebenzi wokuthatha izithombe ezishisayo?
Ukuthwebula izithombe ezishisayo kungaba ubuchwepheshe obuncane nobusebenzayo. Umthwebuli wezithombe ezishisayo olula kakhulu angahlola umthombo wokushisa ogxile ezinweleni eziphambene. Izinhlelo eziyinkimbinkimbi kakhulu zinikeza amaphuzu amaningi okuqhathanisa, ngakho abasebenzisi bangahlaziya izimo zemvelo. Iphalethi yesithombe esishisayo iyahlukahluka kakhulu, kusukela kuphalethi elinombala ofanayo kuya kuphalethi ephelele "yombala ongamanga".
Yini okufanele uyibheke emishinini yokuthwebula izithombe ezishisayo?
Ngokukhethekile, isidingo sakho sesithombe esishisayo sincike endaweni oyisebenzisayo. Kodwa-ke, izindawo ezimbili ziyizici ezibalulekile ezihlukanisa ikhwalithi yabathwebuli bezithombe ezishisayo: isixazululo se-detector kanye nokuzwela kokushisa.
Njengezinye izinqumo eziningi, isinqumo sichaza inani eliphelele lamaphikseli - isibonelo, isinqumo esingu-160×120 siqukethe amaphikseli angu-19200. Iphikseli ngayinye inedatha yayo yokushisa ehlobene, ngakho isinqumo esikhulu singaveza isithombe esicacile.
Ukuzwela kokushisa kuwumkhawulo womehluko ongatholwa ngumthwebuli wezithombe. Isibonelo, uma ukuzwela kwedivayisi kungu-0.01 °, izinto ezinomehluko wokushisa wephesenti elilodwa zingahlukaniswa. Amabanga okushisa amancane naphezulu nawo abalulekile.
Izithombe ezisebenzisa ukushisa zinemikhawulo ethile eyisisekelo: isibonelo, azikwazi ukudlula engilazini ngenxa yezakhiwo ezibonakalayo zezinto. Zisakwazi ukubona kodwa azikwazi ukungena odongeni. Noma kunjalo, izithombe ezisebenzisa ukushisa ziye zaba usizo ezinhlelweni eziningi.
