I-Liquid Lens Technology, Imfihlo Engemuva Kwesivinini sokugxila kwe-0.1-Second yama-Smartphoneeras

Emkhakheni wokuthwebula izithombe ze-smartphone, isivinini sokugxila besilokhu singenye yezinkomba eziyinhloko zokuhlangenwe nakho komsebenzisi. Amalensi okukhanya endabuko ancike ezintweni zelensi yokunyakaza ukuze afinyelele ukugxila, futhi isivinini sawo sokuphendula sivamise ukukhawulwa yi-inertia yokunyakaza komzimba. Ukuvela kobuchwepheshe belensi ewuketshezi kuwuphule ngokuphelele lo mjondolo. Ngokuhlanganisa izimiso ze-bionics nezinto eziqanjiwe, amalensi awuketshezi athuthukise isivinini sokugxila ezingeni le-millisecond, okuletha impumelelo eguquguqukayo ekucabangeni kweselula.

Umnyombo wamalensi awuketshezi usekushintsheni uhlobo oluphathekayo lwe-liquid ukufinyelela umthethonqubo wobude bokugxila. Umgomo wayo ufana nelensi yeso lomuntu: lapho imisipha ye-ciliary inkontileka, ilensi ishintsha ukugoba kwayo ngokuguqulwa ukuze iqedele. Amalensi awuketshezi asebenzisa umphumela wokumanzisa i-electro-wetting noma ubuchwepheshe obuqhutshwa yingcindezi, ehlanganisa uketshezi olubili olungaguquki (njengamanzi namafutha) ku-microcontainer, kanye nokushintsha ukushuba kwesixhumi esibonakalayo soketshezi ngokusebenzisa i-voltage, okwenza amaconsi oketshezi akhe indawo ejikajikayo egobile. Lokhu kulungiswa okungekona okwenziwa ngomshini kukhulula inqubo yokugxila emikhawulweni engokomzimba yamamotho avamile ekhoyili ezwi. Uma sithatha i-Xiaomi MIX FOLD njengesibonelo, imojula yayo yelensi ewuketshezi ilawula ukuguqulwa kwelensi ewuketshezi ngokusebenzisa i-voltage, futhi ingaqedela ukugxila okuqhubekayo ukusuka ku-telephoto kuya ku-macro phakathi kwama-microseconds ayi-10. Le "mpendulo yeleveli ye-millisecond" ithuthukisa kakhulu kuphela izinga lempumelelo yokuthwebula izinto eziguqukayo kodwa futhi ifinyelela ikhono lokudubula elikhulu kakhulu amalensi endabuko akuthola kunzima ukulibhalansisa, ephushela umkhawulo oseduze wokugxila wokuthwebula uye kuleveli yamasentimitha.

Ukugxila okushesha kakhulu, akukho ukubambezeleka ekuthwebuleni: Umshini womdabu ugxile ekuhambeni kwamaqembu amalensi, anesikhathi sokuphendula esijwayelekile esingama-millisecond angu-200-300. Ijubane lokuwohloka koketshezi lwelensi ewuketshezi lilinganiselwe kuphela ukunyakaza kwamangqamuzana, futhi isivinini sokugxila singafinyelela phakathi kwamasekhondi angu-0.1. Lokhu kuphumelela kubaluleke kakhulu ezindaweni ezinokukhanya okuphansi - uma kunokukhanya, ilensi ewuketshezi ayidingi ukuncika osizweni lokugxilisa i-laser, futhi ingakhiya ngokunembile ukugxila ngokulungisa ngokushesha ukugoba, ukugwema izithombe ezifiphele ezibangele ukusesha okuphindaphindiwe kobuchwepheshe bendabuko.

Ukulungiswa kwesikhala, kuncane futhi kungasindi ngokusebenza: Idizayini yelensi ewuketshezi ngaphandle kwesakhiwo somshini ilondoloza isikhala sangaphakathi esiyigugu somakhalekhukhwini. Isibonelo, imojuli yasekuqaleni yelensi ye-liquid yakwa-Samsung yandisa kuphela ukujiya ngo-2mm ukuze kufinyelelwe ukumbozwa kobude obuphelele obugxilile ukusuka ku-5cm kuya kokungapheli. Lesi sici sikhuthaza ukuthuthukiswa kwe-miniaturization yamamojula wekhamera yeselula: I-Xiaomi ihlanganisa imisebenzi ye-telephoto kanye ne-macro ngamalensi awuketshezi, isusa isidingo samalensi amakhulu ahlukene, nokusebenza kokubona kuyilapho igcina umzimba omncane futhi ongasindi.

Ukuthuthukiswa okubanzi ekusebenzeni kokubona: Ukunemba kokugoba kwamalensi awuketshezi kungafinyelela izinga le-nanometer, kunciphise izinkinga zokungalungi ezibangelwa ukubekezelelwa kwemishini kwamalensi endabuko. Ilungelo lobunikazi lelensi ewuketshezi ye-Huawei libonisa ukuthi ngokuthuthukisa inkomba ye-refractive yoketshezi kanye nokuma kwejika, ingathuthukisa ngokuphawulekayo ukucija kanye nekhono lokukhiqiza umbala wesithombe kuyilapho iqinisekisa ukudluliswa okuphezulu kanye nokunciphisa ukuphuma kwe-chromatic. ngaphezu kwalokho, ukujula okuguquguqukayo komsebenzi wokulungisa inkambu yelensi ewuketshezi kwenza amafoni omakhalekhukhwini afinyelele imiphumela yokushintsha ukugxila kwesinema ngesikhathi sokushuthwa kwevidiyo.

Izicelo Zemboni kanye Nezitayela Zesikhathi esizayo

Ubuchwepheshe be-lens ye-Liquid akuyona i-pie esibhakabhakeni, ukuthuthukiswa nokusebenza kwayo sekuye kwaqoqwa amashumi eminyaka. Kusukela ngo-2000, iNyuvesi yaseCalifornia, e-U.S.A., yasebenzisa amalensi awuketshezi kumabonakude wezinkanyezi, yakha izibonisi ze-parabolic ngokuzungeza i-mercury, izindleko zokukhiqiza ezingaphezu kuka-90%. Emkhakheni we-electronics yabathengi, inkampani yaseFrance i-Varioptic yethule imodyuli yokuqala ye-lens liquid lens ngo-204, ivula inqubo yokuthengisa lobu buchwepheshe. Namuhla, amalensi awuketshezi asephenduke ingqikithi yokuqanjwa kabusha ekamu le-Android. Ngaphezu kwe-Xiaomi Huawei, abanye abakhiqizi abanjenge-vivo ne-OPPO bathuthukisa nobuchwepheshe obuhlobene. Ngokuthuthuka kobuchwepheshe bokukhiqiza, isivuno nokuzinza kwamalensi awuketshezi kuye kwathuthuka ngokuqhubekayo, futhi izindleko zawo zehlile zisuka enanini elimba eqolo lezinsuku zakuqala zaya ezingeni elingakhiqizwa ngobuningi. Ngokuzayo, lobu buchwepheshe kulindeleke ukuthi buqhubeke buhlanganiswe nama-algorithms e-AI, kuzuzwe ukugxila okusekelwe esigcawini okuhlakaniphe kakhudlwana, futhi kungase kuguqule ngisho ne-design logic yamamojula endabuko optical.

Ubuchwepheshe belensi ye-liquid yokuvuthwa busho uguquko lwesu lokuthwebula izithombe zeselula ukusuka "ku-hardware stacking" kuya "ku-smart optimization". Ayigcini nje ngokuchaza kabusha izinga lokugxila lokucabanga kodwa futhi ivula ipharadigm entsha yokuklama okubonakalayo. Lapho lobu buchwepheshe obumnyama obuvela ku-bionics buhlanganiswe ngokujulile nezithombe zekhompyutha ze-AI, ama-smartphone angase alethe igagasi lokuthuthuka eliguquguqukayo kakhulu kune-" inkathi yamakhamera amaningi".
