Ake siqale ngombono oyisisekelo. Wonke amakhamera ashisayo asebenza ngokuthola ukushisa, hhayi ukukhanya. Lokhu kushisa kubizwa ngokuthi i-infrared noma amandla ashisayo. Yonke into ekuphileni kwethu kwansuku zonke ikhipha ukushisa. Ngisho nezinto ezibandayo njengeqhwa zisakhipha amandla amancane ashisayo. Amakhamera ashisayo aqoqa la mandla futhi awaguqule abe izithombe esingaziqonda.
Kunezinhlobo ezimbili eziyinhloko zamakhamera ashisayo: apholile futhi angapholi. Zombili zifeza injongo efanayo—ukuthola ukushisa—kodwa zikwenza ngezindlela ezihlukene. Ukuqonda indlela abasebenza ngayo kusisiza ukuba sibone ukungezwani kwabo ngokucacile.
Amakhamera Ashisayo Angapholile
Amakhamera ashisayo angapholisiwe awuhlobo oluvame kakhulu. Abadingi ukupholisa okukhethekile ukuze basebenze. Kunalokho, basebenzisa izinzwa ezisabela ekushiseni ngokuqondile okuvela endaweni ezungezile. Lezi zinzwa ngokuvamile zenziwe ngezinto ezifana ne-vanadium oxide noma i-amorphous silicon. Zigcinwa ezingeni lokushisa elilingana negumbi.
Amakhamera angapholisiwe alula futhi anokwethenjelwa. Futhi mancane, alula, futhi ayathengeka. Ngenxa yokuthi awadingi amasistimu okupholisa, angaqala ngokushesha futhi asebenzise amandla amancane. Lokho kuzenza zibe zinhle kumadivayisi aphathwayo, izimoto, ama-drones, namathuluzi amaningi ezimboni.
Nokho, amakhamera angapholisiwe anemikhawulo ethile. Ikhwalithi yesithombe sabo yinhle, kodwa ayibukhali njengaleyo yamakhamera apholile. Bangase futhi babhekane nobunzima bokubona umehluko omncane kakhulu wamazinga okushisa, ikakhulukazi ezindaweni ezikude. Kwezinye izimo, angathatha isikhathi eside ukugxila futhi angase athintwe ukushisa kwangaphandle.
Amakhamera Apholile Ashisayo
Amakhamera apholile asebenza ngokuhlukile. Bane-cooler eyakhelwe ngaphakathi ye-cryogenic eyehlisa izinga lokushisa lenzwa yabo. Le nqubo yokupholisa isiza inzwa ukuthi izwele kakhulu emandleni amancane we-infrared. Lawa makhamera angakwazi ukubona izinguquko ezincane kakhulu ezingeni lokushisa—ngezinye izikhathi zibe mancane njengo-0,01°C.
Ngenxa yalokhu, amakhamera apholile ahlinzeka ngezithombe ezicacile, ezinemininingwane eminingi. Bangakwazi futhi ukubona kude futhi bathole okuqondiwe okuncane. Zisetshenziswa kumishini yesayensi, yezempi, yezokuvikela, neyokusesha nokuhlenga, lapho ukunemba okuphezulu kubalulekile.
Kodwa amakhamera apholile afika nokuhwebelana okuthile. Abiza kakhulu, asindayo, futhi adinga ukunakekelwa okwengeziwe. Amasistimu abo okupholisa angathatha isikhathi ukuqalisa futhi angase adinge ukunakekelwa okuvamile. Ezimweni ezinzima, izingxenye zabo ezithambile zingaba sengozini yokulimala.
Umehluko Obalulekile
● Uhlelo Lokupholisa: Amakhamera apholisiwe adinga isipholile esikhethekile. Amakhamera angapholisiwe awenzi.
●Ukuzwela: Amakhamera apholile athola izinguquko ezincane zokushisa. Ezingapholisiwe azizwela kakhulu.
●Ikhwalithi Yesithombe: Amakhamera apholisiwe akhiqiza izithombe ezibukhali. Ezingapholisiwe ziyisisekelo kakhulu.
●Izindleko kanye nosayizi: Amakhamera angapholisiwe ashibhile futhi ahlangene. Ezipholile ziyabiza futhi zikhudlwana.
●Isikhathi Sokuqalisa: Amakhamera angapholisiwe asebenza ngaso leso sikhathi. Amakhamera apholisiwe adinga isikhathi sokuphola ngaphambi kokusetshenziswa.
Iyiphi Oyidingayo?
Uma udinga ikhamera eshisayo ukuze uyisebenzise ngokujwayelekile—njengokuhlola ikhaya, ukushayela, noma ukugadwa okulula—ikhamera engapholiswanga ngokuvamile yanele. Iyathengeka, kulula ukuyisebenzisa, futhi ihlala isikhathi eside.
Uma umsebenzi wakho udinga ukunemba okuphezulu, ukutholwa kwebanga elide, noma ukubona umehluko omncane kakhulu wezinga lokushisa, ikhamera epholile iyinketho engcono. Ithuthuke kakhulu, kodwa iza ngentengo ephezulu.
Ngamafuphi, zombili izinhlobo zamakhamera ashisayo zinendawo yazo. Ukukhetha kwakho kuncike kulokho okudingeka ukubone, ukuthi udinga ukukubona ngokucacile kangakanani, nokuthi uzimisele ukusebenzisa malini. Ukuthwebula izithombe ezishisayo kuyithuluzi elinamandla, futhi ukwazi umehluko phakathi kwezinhlelo ezipholile nezingapholisiwe kukusiza ukuthi ukusebenzise ngokuhlakanipha.
