Tag nrho cov tshuab tsis pom kev muaj lub hom phiaj sib xws, uas yog txhawm rau ntes thiab tshuaj xyuas cov ntaub ntawv kho qhov muag, kom koj tuaj yeem tshawb xyuas qhov loj thiab cov yam ntxwv thiab txiav txim siab sib xws. Txawm hais tias lub tshuab pom lub tshuab ua rau muaj qhov tseeb zoo heev thiab txhim kho cov khoom tsim tau zoo heev. Tab sis lawv cia siab rau cov duab zoo uas lawv tau noj. Qhov no yog vim tias cov tshuab no tsis txheeb xyuas cov ntsiab lus nws tus kheej, tab sis theej cov duab nws ntes. Nyob rau hauv tag nrho lub tshuab tsis pom kev, lub tshuab pom lub lens yog ib qho tseem ceeb imaging tivthaiv. Yog li xaiv cov lo ntsiab muag zoo yog qhov tseem ceeb heev.
Ib qho tseem ceeb tshaj plaws uas peb yuav tsum xav txog yog lub sensor ntawm lub koob yees duab thaum xaiv lub lens siv hauv daim ntawv thov pom lub tshuab. Qhov tseeb lens yuav tsum txhawb nqa qhov loj me thiab pixel loj ntawm lub koob yees duab. Txoj cai lo ntsiab muag tsim cov duab zoo kawg nkaus phim cov khoom uas tau ntes, suav nrog tag nrho cov ntsiab lus thiab qhov ci ntsa iab.
FOV yog lwm qhov tseem ceeb uas peb yuav tsum xav txog. Yuav kom paub qhov twg FOV yog qhov zoo tshaj rau koj, nws yog qhov zoo tshaj plaws los xav txog cov khoom koj xav ntes ua ntej. Feem ntau hais lus, qhov loj dua qhov khoom koj tab tom ntes, qhov loj dua qhov kev pom koj yuav xav tau.
Yog tias qhov no yog daim ntawv thov tshuaj xyuas, kev txiav txim siab yuav tsum tau muab rau seb koj tab tom saib tag nrho cov khoom lossis tsuas yog qhov koj tab tom tshuaj xyuas. Siv cov qauv hauv qab no peb tuaj yeem ua haujlwm tawm qhov Primary Magnification (PMAG) ntawm qhov system.
Qhov kev ncua deb ntawm qhov kev kawm thiab qhov kawg ntawm lub lens yog hu ua qhov kev ncua deb ntawm kev ua haujlwm. Nws tuaj yeem yog qhov tseem ceeb heev kom tau txais txoj cai hauv ntau lub tshuab tsis pom kev, tshwj xeeb tshaj yog thaum lub teeb pom kev zoo yuav tsum tau nruab rau hauv cov xwm txheej hnyav lossis qhov chaw txwv. Piv txwv li, nyob rau hauv tej yam kev mob hnyav xws li huab cua kub, plua plav thiab av, lub lens nrog kev ua haujlwm ntev yuav zoo dua rau kev tiv thaiv lub cev. Qhov no txhais tau hais tias koj yuav tsum xav txog qhov kev pom zoo nrog rau kev nthuav dav kom nthuav tawm cov khoom kom meej meej li sai tau.
