Raws li lub zeem muag engnedded, koj ib txwm nrhiav kev muaj tswv yim kev txhim kho cov kev xav cov tshuab. Cov cuab yeej ua kua kua yog ib qho kev ua si {{1} Hloov cov khoom siv uas ua tau dab tsi hauv kev cog lus, siab} ceev, thiab lub zog ceev, thiab lub zog ruaj khov. Hauv tsab xov xwm no, peb yuav delve rau hauv cov ntsiab lus ntawm kua lens technology, pib nrog nws cov txheej txheem yooj yim thiab xaus nrog kev ua haujlwm ntawm kev siv. Peb tseem yuav nyob ze cov lus nug xws li dab tsi yog cov kua lens, siv lub ntsej muag ua kua, thiab kua qaub ua kua rau hauv VCM Auto {{8- Tsom. Peb kuj yuav ntsuas qhov zoo & tsis zoo ntawm cov lens kua kom zoo kom koj tuaj yeem txiav txim siab seb nws puas yog qhov zoo tagnrho kev daws rau koj txoj haujlwm tom ntej.
Dab tsi yog kua lens ua kua?
Cov ntsiab lus ua kua, hauv cov lus qhia ua kua, yog hom kev siv hluav taws xob siv hluav taws xob, uas tso cai rau lub lens lub lens hloov yam tsis muaj kev txav mus los. Ntau dua li siv cov tawv tawv ntawm iav lossis yas, kua roj ua kua ntawm cov kua hauv lub cev (feem ntau yog dej thiab roj), txhawm rau hloov lub focal ntev. Qhov "cov kua dej" cov yam ntxwv ua rau pom zoo sai thiab muaj tseeb.
Lub tswv yim no tshiabKua Lens Tshuabmuab cov khoom tsis muaj kev hloov pauv. Nws ua rau kev tsom xam ceev ceev, zooming, thiab aberration kev txhim kho, tag nrho nyob rau hauv ib daim qauv sib xyaw. Nws tsim Inherently txo cov khaub ncaws hnav thiab kua muag uas muaj cov tshuab tsoos, cog lus ncua sijhawm ntev thiab muaj kev cia siab hauv cov chaw xav tau.
Yuav ua li cas ua kua lens koob yees duab ua haujlwm?
Ntawm lub siab aKua Lens Koob Yees Duabyog lub electro - ntub σ} ntub tshwm sim. Xav txog ob cov kua uas tsis sib xyaw, xws li roj thiab dej, muab tso rau hauv ib lub xovtooj me. Ib qho kua yog kev coj ua, lwm qhov tsis - kev ua. Thaum hluav taws xob voltage yog thov rau cov kua ua kua, nws cov npoo nrawm hloov.
Qhov kev hloov pauv ntawm cov npoo npoo ntawm cov kua curvature ntawm cov kua - kua xyaw interface, zoo hloov lub lens lub focal ntev. Nce cov voltage, thiab kev hloov nkhaus hauv ib qho kev taw qhia; Txo nws, thiab nws hloov rov qab. Cov txheej txheem no yog nrawm kawg, tso cai rau autofocus thiab tob {}} ntawm {4 4} {4 4} {4 4} {4 4}.
Qhov sib txawv ntawm cov kua ua kua thiab tsoos lens
TusQhov sib txawv ntawm cov kua ua kua thiab tsoos lensyog muaj txiaj ntsig, cuam tshuam kev tsim, kev ua tau zoo, thiab ntawv thov. Cov iav qaub ncaug cia siab rau cov tshuab txav ntawm iav rigid iav lossis cov khoom yas hloov kom pom tseeb. Qhov no suav nrog cov motors, zog, thiab cov rooj sib txoos sibtham.
Hauv kev sib piv, akua lensUa tau kom muaj tseeb purely hluav taws xob, tsis muaj cov tshuab sib txuam nrog. Qhov kev sib txawv no ua rau ob peb lub ntsiab lus tseem ceeb: ceev, kav ntev, thiab kev sib cav. Txawm li cas los xij, nws tseem qhia cov kev txiav txim siab tshwj xeeb rau kev sib koom ua ke, xws li qhov kub thiab txias rhiab thiab tsav hluav taws xob tshwj xeeb.
Yuav ua li cas kua lens autofocus txawv los ntawm VCM autofocus?
Ib qho ntawm cov ntsiab lus tseem ceeb pov thawj yuav tsum paub: Lens lens autofocus txawv ntawm VCM autofocus? Lub autofocus pom nyob rau hauv VCM (Suab Coil lub cev muaj zog) tshuab, uas tau siv nyob rau hauv lub xov tooj smartphones, yog ua los ntawm kev txav lub ntsej muag rov qab thiab siv lub coil thiab hlau nplaum. Nws yog cov txheej txheem tshuab, hauv qhov kev txiav txim siab, uas nws yog constrained los ntawm inertia thiab kev sib txhuam.
Kua lens autofocus, Conversely, yog nkaus hluav taws xob thiab tsis - tshuab. Nws cia siab rau hloov cov duab ntawm cov kua interface ntawm electro - ntub dej. Qhov no txhais tau ze- instantant teb cov sijhawm, feem ntau hauv milliseconds, piv rau ntau pua milliseconds rau vcms. Qhov ceev no thiab tsis muaj txav txavKua Lens TshuabQhov zoo tagnrho rau high - cua ncauj los yog kev siv hnyav.
Qhov zoo & tsis zoo ntawm cov kua lens
