1,Lub lens pinhole yog dab tsi?
Lub lens pinhole, raws li lub npe qhia, yog lub lens me me heev, nws qhov aperture tua tsuas yog qhov loj ntawm lub pinhole, nws yog lub lens siv los ntawm ultra-micro koob yees duab. Pinhole lens siv lub hauv paus ntsiab lus ntawm qhov me me imaging kom tau txais cov duab thiab muaj qee yam tshwj xeeb thiab daim ntawv thov.
2,Cov yam ntxwv ntawm lub lens pinhole yog dab tsi?
Ua ib qho khoom siv tshwj xeeb ntawm lub koob yees duab, lub lens pinhole muaj qee yam tshwj xeeb:
(1)Qhov tsos zais cia
Cov qhov me me ntawm lub lens pinhole yog me heev thiab zoo ib yam li qhov loj ntawm lub qhov pinhole. Vim yog lub qhov me me, qhov loj ntawm tag nrho lub koob yees duab pinhole yog me heev, feem ntau tsuas yog qhov loj ntawm npib xwb. Qhov kev tsim me me no ua rau lub koob yees duab pinhole zais tau yooj yim hauv ntau qhov chaw, thiab nws nyuaj rau paub txog nws.
(2)Zoo kawg lisxwm txheejitus kws ua khawv koob
Vim yog qhov tsim tshwj xeeb ntawm lub lens pinhole, nws qhov tob ntawm daim teb yog qhov tob heev thiab tuaj yeem tua cov duab tob heev. Qhov no txhais tau tias cov khoom nyob rau pem hauv ntej ntawm lub koob yees duab tuaj yeem pom tseeb ntawm qhov chaw thaij duab tsis hais qhov deb npaum li cas. Raws li qhov tshwj xeeb no, lub lens pinhole ua tau zoo thaum thaij duab toj roob hauv pes thiab architecture xav tau qhov pom tseeb loj.
(3)Qhov ntev ntawm qhov focal thiab qhov aperture ruaj khov
Lublub lens qhovfeem ntau tsis muaj qhov ntev ntawm lub lens thiab qhov aperture uas hloov kho tau. Thaum twg ntsia tau lawm, lub kaum sab xis thiab lub peev xwm txais lub teeb ntawm lub lens raug kho. Txawm hais tias qhov no tsuas yog txwv rau qhov yooj yim ntawm kev tua duab xwb, nws kuj ua rau lub lens pinhole yooj yim dua thiab siv tau yooj yim.

(4)Kev ua tau zoo tsawg hauv qhov chaw tsis muaj teeb pom kev zoo
Vim tias lub lens pinhole muaj qhov me me thiab muaj lub teeb tsawg, qhov kev tua duab hauv qhov chaw tsaus ntuj yuav tsis zoo. Qhov no yuav ua rau muaj teeb meem xws li cov duab tsis meej thiab xim tsis sib xws, thiab xav tau cov teeb pom kev ntxiv lossis cov khoom siv pabcuam los txhim kho qhov kev tua duab.
(5)Phau Ntawv Qhiasteeb tsa
Feem ntau cov iav tsom iav Pinhole tsis muaj cov yam ntxwv siab heev xws li autofocus thiab xav tau kev teeb tsa thiab kev kho kom haum tes. Qhov no ua rau kev ua haujlwm nyuaj dua rau qee qhov, tab sis kuj muab kev ywj pheej ntau dua, uas ua rau cov kws thaij duab hloov kho tau raws li qhov xav tau tshwj xeeb.
(6)Ntau yam kev siv
Qhov zais thiab yooj yim siv ntawmcov iav qhov muagua rau lawv siv dav hauv ntau qhov chaw. Txawm hais tias nws yog kev saib xyuas kev ruaj ntseg hauv tsev, kev saib xyuas chaw ua haujlwm lossis kev saib xyuas qhov chaw pej xeem, cov iav pinhole tuaj yeem ua lub luag haujlwm tseem ceeb. Tib lub sijhawm, lawv kuj siv dav hauv kev tshawb fawb, kev saib xyuas tsheb, kev soj ntsuam tsiaj thiab lwm yam.
3,Cov kev siv ntawm cov iav pinhole yog dab tsi?
Cov cheeb tsam siv ntawm cov iav pinhole feem ntau suav nrog cov hauv qab no:
(1) Kev saib xyuas kev ruaj ntseg
Cov tsom iav Pinhole me me thiab zais tau, yog li lawv tuaj yeem ntsia tau rau hauv cov khoom siv me me thiab siv ua kev saib xyuas kev ruaj ntseg zais. Vim lawv qhov me me, lawv tuaj yeem zais tau yooj yim txhua qhov chaw kom zais tau qhov chaw ib puag ncig.

(2) Kev saib xyuas tsheb khiav
Cov tsom iav pinhole kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tswj hwm kev tsheb hauv nroog. Lawv siv los thaij duab kev ua txhaum cai tsheb, kaw cov xwm txheej sib tsoo tsheb, thiab lwm yam, pab txhim kho kev nyab xeeb tsheb thiab kev tswj hwm kev ua haujlwm zoo.
(3) Kev kos duab
Cov tsom iav pinhole siv rau hauv kev kos duab los tsim cov teebmeem pom kev tshwj xeeb. Vim tias cov tsom iav pinhole muaj qhov tob tsis kawg, lawv tuaj yeem ua rau ob qho tib si pem hauv ntej thiab keeb kwm yav dhau los pom tseeb. Ntau tus kws kos duab thiab cov kws thaij duab siv txoj kev no los tsim kom muaj kev xav zoo li npau suav, rov qab.
(4)Kev tshawb fawb txog kev tshawb fawb
Vim yog cov yam ntxwv ntawmcov iav qhov muag, lawv kuj siv dav hauv kev tshawb fawb txog kev tshawb fawb. Piv txwv li, hauv kev soj ntsuam hnub qub, cov iav pinhole yuav siv tau los soj ntsuam lub hnub lossis lwm lub cev saum ntuj ceeb tsheej. Tib lub sijhawm, cov iav pinhole kuj yog cov cuab yeej tseem ceeb heev hauv kev soj ntsuam cov tshuaj lom neeg me me thiab cov xwm txheej ntawm lub cev atomic.
(5)Kev kho mob teb
Hauv kev siv duab hluav taws xob thiab kev siv tshuaj kho mob nuclear, cov iav pinhole ua lub luag haujlwm tseem ceeb hauv cov txheej txheem thaij duab tsis-invasive xws li PET (positron emission tomography) thiab SPECT (single photon emission computed tomography).

(6)Kev kawm ntawv
Cov iav pinhole kuj tseem siv dav hauv kev kawm, tshwj xeeb tshaj yog hauv kev qhia txog optics thiab kev thaij duab, los pab cov tub ntxhais kawm nkag siab txog lub teeb kis mus rau hauv lub lens li cas thiab cov duab tsim li cas.
(7)Tus kheejpkev thaij duab kub
Qhov zais ntawm lub lens pinhole kuj ua rau nws muaj qee yam kev siv hauv kev thaij duab tus kheej. Tib neeg tuaj yeem zais lub lens pinhole ua cov khoom siv niaj hnub, xws li lub thawv ntawv, tshuaj da dej, teeb me me, thiab lwm yam, rau kev thaij duab zais cia.
Yuav tsum nco ntsoov tias vim nws qhov xwm txheej zais cia, cov iav pinhole kuj yooj yim siv los ntawm cov neeg ua txhaum cai rau kev ua txhaum cai, xws li kev saib xyuas, kev thaij duab zais cia, thiab lwm yam, uas ua rau cov pej xeem tsis pub lwm tus paub thiab muaj lub meej mom.
Yog li ntawd, thaum sivcov iav qhov muag, cov kev cai lij choj, cov cai thiab cov qauv kev coj ncaj ncees yuav tsum tau ua raws li kom ntseeg tau tias lawv raug siv raws li txoj cai thiab ua raws li cov cai.
