Ukuqina kwesithombeIngabe insimbi ebonakalayo engathuthukisa ubukhulu obuphansi obukhanyayo, futhi isetshenziselwa ukwenza into evuthayo i-contour ibonakale esweni elinqunu. Izici eziphambili zesithombe sokuqina kwesithombe zivame ukufaka izinzwa zezithombe, ama-lens we-optical, amashubhu okubona ebusuku, ama-circuits, kanye nokuhlinzekwa kwamandla.
1 Njengamanje, izinzwa eziphambili zezithombe ezisetshenzisiwe yi-CMOS ne-CCD, ngemiphumela ehlukile yokucabanga ehlukile. Kodwa-ke, umgomo oyinhloko ukuguqula izithombe ezikhanyayo zibe amasiginali kagesi.
2. I-Optical Lens Optical Lens ingenye yezinto ezibalulekile zokuqina kwesithombe, okungenza imisebenzi efana nokugxila, ukuhlukanisa, nokuhlanganiswa kwe-lens kokukhanya kwesigameko. Ngokushintsha ukwakheka nosayizi welensi, ukucabanga okukhanyayo kungacaciswa futhi ikhwalithi yesithombe ingathuthukiswa.
3. I-tube yombono ebusuku iyingxenye ebalulekile yesithombe sokuqina kwesithombe, esingathuthukisa isibonakaliso se-elekthronikhi sokukhanya futhi sithuthukise ukuqina kokukhanya ezindaweni eziphansi zokukhanya ebusuku. Umgomo osebenzayo we-Tube Lombono ebusuku ukuguqula izithombe ezitholakele zibe amasiginali kagesi ngezindlela ezinjengokuphindaphindwa kwe-Photoelectric kanye ne-cathode kanye nokuvuseza kwe-anyoode. Ngemuva kokuthuthukiswa futhi kwandiswa yilensi ye-elekthronikhi, bese kuguqulwa kube yizimpawu ezibonakalayo ezibonakalayo ngesendlalelo se-fluorescent.
I-4. Ukuhlinzekelwa kwesekethe nokusebenza kwamandla kwesithombe sokuqina kwesikhungo sokulawula kwesithombe sokuqina kwesithombe. I-Circuit iyisibopho sokulawulwa kokukhulisa, ukucubungula iziginali, kanye nemisebenzi yokukhipha ye-tube yombono wobusuku. Ukunikezwa kwamandla yisiqinisekiso sokusebenza okujwayelekile kwesithombe sokuqina, kufaka phakathi amandla we-DC, amandla e-AC namabhethri. Isifunda kanye nokunikezwa kwamandla nakho kuyizinto ezibalulekile ukuqinisekisa ukusebenza okuzinzile kwesithombe ukuqina kwesithombe. Ukufingqa, ukuqina kwesithombe kuyithuluzi elisezingeni eliphakeme elihlanganiswe nezakhi ezimbalwa ezibalulekile, kufaka phakathi inzwa yezithombe, ilensi ye-optical, ishubhu yombono wobusuku, umjikelezo kanye nokunikezwa kwamandla. Ukushintshwa kwalezi zingxenye kwenza ukuthi isithombe siqine sibe nezinzuzo zokuthuthuka okunamandla kwamandla aphezulu akhanyayo, ukuthuthukiswa kwekhono lokubuka ebusuku, njll. Isetshenziswa kabanzi kwezempi, amaphoyisa, ezokwelashwa, ucwaningo lwesayensi kanye nezinye izinkambu eziningi.
