Masiqale ngengcinga esisiseko. Zonke iikhamera ezisebenzisa ubushushu zisebenza ngokufumanisa ubushushu, hayi ukukhanya. Olu bushushu lubizwa ngokuba yi-infrared okanye amandla obushushu. Yonke into ebomini bethu bemihla ngemihla ikhupha ubushushu. Kwanezinto ezibandayo ezifana nomkhenkce zisakhupha amandla amancinci obushushu. Iikhamera ezisebenzisa ubushushu ziqokelela la mandla zize ziwaguqule abe yimifanekiso esinokuyiqonda.
Kukho iintlobo ezimbini eziphambili zeekhamera ezishushu: ezipholileyo nezingapholiswanga. Zombini zisebenza injongo enye—ukubona ubushushu—kodwa zikwenza ngeendlela ezahlukeneyo. Ukuqonda indlela ezisebenza ngayo kusinceda sibone umahluko wazo ngokucacileyo.
Iikhamera ze-Thermal ezingapholiyo
Iikhamera zobushushu ezingapholiyo zezona zixhaphakileyo. Azidingi kupholisa okukhethekileyo ukuze zisebenze. Endaweni yoko, zisebenzisa iisensa eziphendula ngqo kubushushu obuvela kwindawo engqongileyo. Ezi sensa zihlala zenziwe ngezinto ezifana ne-vanadium oxide okanye i-silicon engenasimo. Zigcinwa kubushushu begumbi.
Iikhamera ezingapholiswanga zilula kwaye zithembekile. Zincinci, zilula, kwaye zifikeleleka lula. Ngenxa yokuba azidingi iinkqubo zokupholisa, zinokuqalisa ngokukhawuleza kwaye zisebenzise umbane omncinci. Oko kuzenza zibe zilungele izixhobo eziphathwayo, iimoto, iidrone, kunye nezixhobo ezininzi zoshishino.
Nangona kunjalo, iikhamera ezingapholiswanga zinemida ethile. Umgangatho womfanekiso wazo ulungile, kodwa awubukhali njengoweekhamera ezipholisiweyo. Zisenokusokola nokubona umahluko omncinci kakhulu kubushushu, ingakumbi kumgama omde. Kwezinye iimeko, zinokuthatha ixesha elide ukugxila kwaye zinokuchaphazeleka bubushushu bangaphandle.
Iikhamera zeThermal ezipholileyo
Iikhamera ezipholileyo ezishushu zisebenza ngendlela eyahlukileyo. Zine-cryogenic cooler eyakhelwe ngaphakathi ehlisa ubushushu be-sensor yazo. Le nkqubo yokupholisa inceda i-sensor ukuba ibe novelwano ngakumbi kumandla amancinci e-infrared. Ezi khamera zinokubona utshintsho oluncinci kakhulu kubushushu—ngamanye amaxesha lube ncinci njenge-0.01°C.
Ngenxa yoku, iikhamera ezipholileyo zibonelela ngemifanekiso ecacileyo neneenkcukacha ezingaphezulu. Ziyakwazi nokubona kude kwaye zibone iithagethi ezincinci. Zisetyenziswa kwisayensi, emkhosini, kukhuseleko, nakwimisebenzi yokukhangela nokuhlangula, apho ukuchaneka okuphezulu kubalulekile.
Kodwa iikhamera ezipholileyo ziza nezinye izinto ezitshintshiselanayo. Zibiza kakhulu, zinzima, kwaye zifuna ukhathalelo olungakumbi. Iinkqubo zazo zokupholisa zinokuthatha ixesha ukuqala kwaye zinokufuna ukulungiswa rhoqo. Kwiimeko ezinzima, iindawo zazo ezibuthathaka zinokuba sesichengeni sokonakala.
Umahluko oPhambili
● Inkqubo yokupholisaIikhamera ezipholileyo zifuna isibandisi esikhethekileyo. Iikhamera ezingapholiswanga azidingi sibandisi sikhethekileyo.
●UvelwanoIikhamera ezipholileyo zibona utshintsho oluncinci kubushushu. Ezingapholiswanga azinamvakalelo kangako.
●Umgangatho woMfanekisoIikhamera ezipholileyo zivelisa imifanekiso ebukhali ngakumbi. Ezingapholiyo zilula kakhulu.
●Ixabiso kunye nobukhuluIikhamera ezingapholiswanga zibiza kancinci kwaye zincinci. Ezipholiswayo zibiza kakhulu kwaye zinkulu.
●Ixesha lokuqalisaIikhamera ezingapholiswanga zisebenza ngoko nangoko. Iikhamera ezipholisiweyo zifuna ixesha lokuphola ngaphambi kokuba zisetyenziswe.
Yeyiphi Oyifunayo?
Ukuba ufuna ikhamera yobushushu ukuze isetyenziswe ngokubanzi—njengokuhlola ikhaya, ukuqhuba, okanye ukujonga nje—ikhamera engapholiswanga idla ngokwanela. Ifikeleleka lula, kulula ukuyisebenzisa, kwaye ihlala ixesha elide.
Ukuba umsebenzi wakho ufuna ukuchaneka okuphezulu, ukubonwa komgama omde, okanye ukubona umahluko omncinci kakhulu kubushushu, ikhamera epholileyo yeyona ndlela ingcono. Iphucuke ngakumbi, kodwa iza ngexabiso eliphezulu.
Ngamafutshane, zombini ezi ntlobo zeekhamera ezisebenzisa ubushushu zinendawo yazo. Ukhetho lwakho luxhomekeke kwinto ekufuneka uyibone, ukuba kufuneka uyibone ngokucacileyo kangakanani, kunye nokuba uzimisele ukuchitha malini. Imifanekiso esebenzisa ubushushu sisixhobo esinamandla, kwaye ukwazi umahluko phakathi kweenkqubo ezipholileyo nezingapholiyo kukunceda uyisebenzise ngobulumko ngakumbi.
