(2)Lub lens telecentric
Lub lens telecentric yog ib hom lens tshwj xeeb ntawm lub koob yees duab kev lag luam nrog txoj kev pom ntev, uas tuaj yeem ua tiav qhov tob ntawm daim teb thiab cov nyhuv tua duab siab. Hom lens no feem ntau yog siv rau hauv cov txheej txheem tshuaj xyuas pom kev siab thiab ruaj khov, xws li kev pom tshuab, kev ntsuas qhov tseeb thiab lwm yam.
Cov iav tsom iav rau kev lag luam
(3)Lens luam theej kab
Lub lens scan kab yog lub lens scanning ceev ceev siv rau cov koob yees duab scan kab lossis CMOS koob yees duab. Nws tuaj yeem ua tiav kev luam theej duab ceev ceev thiab raug, thiab nws tsim nyog rau kev tshuaj xyuas zoo thiab txheeb xyuas cov kab ntau lawm ceev ceev.
(4)Lub lens varifocal
Lub lens varifocal yog lub lens uas tuaj yeem hloov qhov loj me. Nws tuaj yeem hloov kho rau ntau yam kev xav tau ntawm kev tshuaj xyuas los ntawm kev kho qhov loj me. Nws yog qhov tsim nyog rau kev tshuaj xyuas qhov chaw raug, kev tshawb fawb thiab lwm yam xwm txheej.
Los ntawm kev xaiv hom lens thiab cov chaw teeb tsa uas haum rau lub koob yees duab, koj tuaj yeem tau txais cov teebmeem zoo thiab cov txiaj ntsig kev tshuaj xyuas pom tseeb. Tib lub sijhawm, siv cov khoom zoo thiab ruaj khovcov koob yees duab kev lag luamkuj tseem tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom thiab txo cov nqi kho.
Yog li ntawd, rau cov neeg koom nrog kev pom kev ntawm lub tshuab thiab kev ua cov duab, nws yog qhov tsim nyog heev kom nkag siab thiab paub txog cov hom, cov ntsiab cai xaiv thiab cov txheej txheem siv ntawm cov koob yees duab kev lag luam.
2.Cov ntsiab cai xaiv ntawm cov iav koob yees duab kev lag luam
(1)Kev txiav txim siab seb puas yuav xaiv qhov kev tsom mus rau ib qho lossisvlub lens arifocal
Cov tsom iav uas tsom ntsoov tas li muaj qhov zoo ntawm kev cuam tshuam me me thiab kev ua haujlwm pheej yig, thiab siv dav hauv cov txheej txheem tshuaj xyuas pom. Txawm li cas los xij, qee qhov xwm txheej uas qhov chaw pom kev yuav tsum tau hloov, cov tsom iav zoom yog qhov kev xaiv.
Thaum lub sijhawm ua haujlwm ntawm kev thaij duab ntawmkev pom kev ntawm lub tshuablub kaw lus, nws yog qhov tsim nyog los txiav txim siab seb qhov kev loj hlob puas yuav tsum tau hloov. Yog tias yog, yuav tsum siv lub lens varifocal. Txwv tsis pub, lub lens fixed-focus tuaj yeem ua tau raws li qhov xav tau.
Lub lens tsom kwm thiab lub lens varifocal
(2)Txheeb xyuas qhov deb ua haujlwm thiab qhov ntev ntawm lub focal
Feem ntau, qhov deb ua haujlwm thiab qhov ntev ntawm lub lens yuav raug txiav txim siab ua ke. Feem ntau, qhov kev daws teeb meem ntawm lub system yuav raug txiav txim siab ua ntej, thiab qhov kev loj hlob yuav raug txais los ntawm kev sib xyaw ua ke qhov loj me ntawm lub koob yees duab kev lag luam.
Qhov deb ntawm daim duab uas yuav pom tau yog paub los ntawm kev sib xyaw ua ke cov kev txwv ntawm qhov chaw, thiab qhov ntev ntawm lub lens koob yees duab kev lag luam kuj raug kwv yees ntxiv. Yog li ntawd, qhov ntev ntawm lub lens koob yees duab kev lag luam muaj feem cuam tshuam nrog qhov deb ua haujlwm thiab qhov kev daws teeb meem ntawm lub koob yees duab kev lag luam.
(3)Cov kev cai zoo ntawm daim duab
Hauv cov ntawv thov pom kev ntawm lub tshuab, cov neeg siv khoom sib txawv xav tau qhov tseeb ntawm kev kuaj pom sib txawv, thiab qhov zoo ntawm daim duab kuj tseem yuav txawv. Thaum xaiv lub koob yees duab lens kev lag luam, qhov loj ntawm daim duab yuav tsum phim qhov loj ntawm qhov chaw photosensitive ntawm lub koob yees duab kev lag luam, txwv tsis pub qhov zoo ntawm daim duab ntawm ntug kev pom tsis tuaj yeem lav.
Hauv kev siv tshuab ntsuas kev pom kev, qhov zoo ntawm daim duab muaj feem cuam tshuam nrog kev daws teeb meem, qhov nrawm ntawm kev cuam tshuam thiab kev cuam tshuam ntawm lub lens kev lag luam.
