Raws li tus neeg muag khoom lub koob yees duab endoscopic, feem ntau nug txog cov khoom lag luam tsis zoo hauv kev sib tham ntawm cov neeg siv khoom yog thaj tsam ntawm kev pom, focal ntev, qhov tob ntawm qhov chaw, thiab cov khoom nyob deb. Cov txiaj ntsig ntawm plaub qhov tsis muaj feem cuam tshuam nrog kev siv ib puag ncig thiab cov xwm txheej ntawm cov khoom. Hauv qab no, tus editor yuav piav qhia meej txog plaub qhov tsis zoo ntawm lub koob yees duab endoscope thiab lawv txoj kev sib raug zoo.
hais txog ntau yam uas lub lens ntawm lub koob yees duab endoscope tuaj yeem pom. Lub kaum sab xis loj tuaj yeem muab qhov dav dav ntawm qhov pom thiab tsim nyog rau kev kuaj pom ntau lub hom phiaj; lub kaum sab xis me me tuaj yeem muab kev soj ntsuam siab ntawm cov hom phiaj me.
Hauv lub koob yees duab endoscope, qhov kev ncua deb ntawm qhov chaw kho qhov muag ntawm lub lens mus rau CMOS sensor ntawm lub koob yees duab yog qhov ntev focal. Rau endoscopes, qhov ntev focal ntev txiav txim siab lub peev xwm tsom lub teeb tom qab nws dhau los ntawm lub lens.
Object nrug yog hais txog qhov kev ncua deb ntawm cov khoom yuav tsum tau soj ntsuam thiab lub lens endoscope. Qhov deb ntawm qhov khoom yog qhov tseem ceeb hauv kev txiav txim siab qhov loj thiab qhov pom tseeb ntawm cov duab endoscopic. Ib qho khoom me me nyob deb yuav ua rau cov duab loj dua, thiab cov ntsiab lus nyob deb yuav ua qhov muag plooj lossis tsis meej; ib qho khoom loj dua yuav ua rau cov duab me me, tab sis tuaj yeem khaws cia kom pom tseeb dua.
Cov ntaub ntawv plaub yog ua tiav rau ib leeg:
(1) Lub endoscope nrog lub focal ntev luv tuaj yeem muab qhov loj dua ntawm qhov pom thiab qhov ze ze ze, tab sis cov duab yuav tsis pom tseeb lossis cuam tshuam; thaum lub sij hawm endoscope nrog lub focal ntev ntev tuaj yeem muab cov duab meej dua, tab sis qhov kev pom yuav nqaim dua.
(2) Nrog rau qhov loj ntawm qhov pom, qhov dav dav thiab qhov tob yog qhov loj, ua rau nws tsim nyog rau kev soj ntsuam qhov loj dua. Nrog rau qhov pom me me, qhov dav dav thiab qhov tob yog qhov me me, uas tsim nyog rau kev soj ntsuam cov ntsiab lus me me thiab xav tau cov ntsiab lus siab.
Cov neeg siv yuav tsum tau xyuam xim rau cov ntsiab lus hauv qab no thaum xaiv lub koob yees duab endoscope:
(1) Qhov loj ntawm cov khoom yuav raug kuaj pom: Yog tias cov khoom yuav raug kuaj pom loj, xaiv qhov loj dua ntawm qhov pom tuaj yeem ua kom ntseeg tau tias tag nrho cov khoom tuaj yeem pom; Txawm li cas los xij, qhov loj dua ntawm qhov kev pom, qhov ntau dua qhov distortion, thiab qhov pom tseeb ntawm cov khoom duab yuav raug cuam tshuam. qee yam cawv. Thiab yog tias cov khoom raug kuaj pom me me, xaiv qhov chaw me me ntawm qhov pom tuaj yeem muab kev soj ntsuam zoo dua thiab cov duab pom tseeb dua.
(2) Qhov tob ntawm cov kav dej ntawm cov khoom yuav tsum tau kuaj pom yog qhov kev ncua deb ntawm lub lens thiab cov khoom yuav raug kuaj pom. Yog tias cov khoom yuav raug kuaj pom nyob ze dua, xaiv qhov ze-tsim endoscope nrog luv luv pib taw tes ntawm qhov tob ntawm thaj tsam tuaj yeem tau txais cov duab pom tseeb dua.
(3) Kev txwv ntawm kev ua haujlwm ib puag ncig: Kev txwv ntawm kev ua haujlwm ib puag ncig (xws li qhov chaw me me, txwv qhov chaw saib, thiab lwm yam) tuaj yeem txwv qhov kev xaiv ntawm qhov chaw saib.
