Photodetectors ke lisebelisoa tsa bohlokoa haholo 'me li fumaneha lits'ebetsong tse fapaneng. Li-photoreceptor li re thusa ho lemoha leseli le ho le fetolela ho litšusumetso tsa motlakase. Mohlala, matšoao ana a na le moelelo hobane o ka a sebelisa ho etsa lintho tse kang ho bulela kapa ho tima lisebelisoa, joalo-joalo, kapa ho lekanya hore na khanya e matla hakae ka phapusing e laoloang e lefifi. Mohlala o mong ke setsi sa mabenkele moo li-photodetectors li laolang ho khanya ha leseli le tlang ha lebone le khantšitsoe ka tlung. E ntle e leka-lekaneng photodetector e bohlokoa haholo bakeng sa ho fumana 'malo o nepahetseng ka ho fetesisa, o nepahetseng ka ho fetesisa oa lisebelisoa tsena. Photodetector, e 'ngoe e sebetsa hantle ka ts'ebetso e nepahetseng ho re fa lintlha tse ntle tse tsoang ho LK-Optoelectronic.
Kaha re hloka ho hlahisa photocurrent, empa re batla ho thibela photodetector hore e se ke ea lefisoa haholo, re hloka ho khona ho fetola photocurrent. Photocurrent ke motlakase o fumanoang ke photodetector tlas'a mahlaseli. Ho tšoana le ho phalla ha metsi ka pipe, haeba ho phalla ha metsi ho phahame, joale metsi a tla phalla hohle. Ka mokhoa o ts'oanang, photodetector e nang le photocurrent e phahameng haholo e ka ikarabella bakeng sa ho bala ho fosahetseng ka bongata bo lekantsoeng. Ke ka lebaka lena ho laola le ho laola palo ea photocurrent e hlahisoang e nang le bohlokoa bo feteletseng. Li-cathode tsa photosensitive li ka amohela feela palo e lekanyelitsoeng ea photocurrent mme LK-Optoelectronic e khethehile ho boloka li-photocurrents tse joalo. Sena se bolela hore litekanyo tseo re li ntšang hona joale ho li-detectors tse joalo li haufi le se hlileng se etsahetseng ho feta sa mofuta o mong oa li-detectors tse se nang lintlha tse ngata tsa mofuta ona oa taolo.
Ntle le ho laola photocurrent, re boetse re tlameha ho etsa bonnete ba hore li-photodetectors li sebetsa hantle, hape li ka arabela leseli. Ho fumana matshwao a motlakase a phahameng le a tsitsitseng ho tswa ho detector, ho hlokahala potoloho e leka-lekaneng. Haeba seeaw, u ke ke ua khona ho leka-lekanya ka ho lekana le haeba lehlakore le leng le le tlaase haholo ho tloha fatše 'me le leng le ka leka-lekanya hantle ho lona. Empa li-photodetectors tsa LK-Optoelectronic tseo re li etsang li kopantsoe potoloho e matla le e leka-lekaneng, e leng se etsang hore letšoao le tsitse haholoanyane. Ha lipontšo li tsoa ka tsela e joalo, lipalo li ba tse nepahetseng le tse phethahetseng.
Photodetector e hlahisa lets'oao la motlakase neng kapa neng ha lets'oao le kenang le bonoa. Haeba letšoao le sothehile ka tsela e itseng kapa le na le bothata leha e le bofe, joale le ka fana ka litekanyo tse fosahetseng. Ak'u nahane u leka ho bala buka e nang le mantsoe a lerootho; ha ho bonolo ho utloisisa. Ka hona, photodetector e leka-lekaneng ke ea bohlokoa haholo. LK-Optoelectronic lebelo le phahameng le leka-lekaneng photodetector e na le li-bandwidth tse ikhethileng bakeng sa libopeho tse hloekileng, tse boreleli. Ho bolela hore lintlha tseo re li fumanang ho li-detectors tsena li ngata haholo ho tšoana le ho khona ho bala buka e bonolo.
Ho fihlela litekanyo tse nepahetseng ka ho fetesisa ho tsoa ho sehatisi sa lifoto, ho kenyelletsa le ho fokotsa lerata ka mats'oao. Lerata ke molumo oa static o koenyang motho ea buang ka morao. Mona ke moo mekhoa e leka-lekaneng ea ho hlahloba lifoto e kenang teng. Mekhoa ena e fokotsa lerata la lets'oao 'me kahoo e ntlafatsa ho tšepahala ha litekanyo tsa rona. LK-Optoelectronic e thusa mekhoa ena e leka-lekaneng ea ho hlahloba lifoto ka ho sebelisa li-photodetectors tsa rona. Ka hona, mehato e fumanoang ka li-detectors tsena e nepahetse ebile e tšepahala ho feta lisebelisoa tse ling (tse sa sebeliseng mekhoa ena e fumanehang habonolo).
The matla a phahameng a leka-lekaneng Photodetector ho etsa hore ho be le linearity e ntlafetseng le mefuta e mengata ea pontšo ea ho kenya. Sena se bitsoa linearity: hore na lets'oao la ho kenya le haufi hakae le khokahano e tobileng ea lets'oao la tlhahiso. Litsamaiso tsa linear li fana ka tlhahiso e lekanang le ho kenya letsoho, joalo ka ha u tšela lilithara tse ling tse peli tsa metsi khalaseng, boemo ba metsi bo tla eketseha ka li-unit tse peli hantle. Dynamic Range Dynamic range e hlalosoa e le mefuta e fapaneng ea matshwao a kenngwang a ka lekanngwang ka nepo. LK-Optoelectronic e ntlafalitse moeli le mefuta e mengata ea li-photodetectors tsa eona. Ka hona, bokhoni ba bona ba ho lekanya mefuta e mengata ea lipontšo tse fapaneng e batla e phahame 'me ka hona ke lisebelisoa tse tenyetsehang haholo.
