Ngaba iiLensi ze-Line Scan zingasetyenziswa njengeeLensi zeKhamera? Yintoni isiphumo sayo somfanekiso?

1,Ngaba iilensi zokuskena umgca zingasetyenziswa njengeelensi zekhamera?

Iilensi zokuskena umgcaaziqhelekanga ukusetyenziswa ngqo njengeelensi zekhamera. Kwiimfuno zefoto kunye neevidiyo ngokubanzi, kusafuneka ukhethe ilensi yekhamera ezinikeleyo.

Iilensi zekhamera zihlala zifuna ukuba noluhlu olubanzi lokusebenza kwe-optical kunye nokuguquguquka ukuze zihambelane neemfuno zokuthwebula iintlobo ezahlukeneyo zemifanekiso kwiimeko ezahlukeneyo. Uyilo kunye nomsebenzi weelensi zokuskena umgca zisetyenziswa kakhulu kwiinkalo zobungcali ezifana nokuhlolwa kwemizi-mveliso, umbono womatshini kunye nokucubungula imifanekiso, kwaye azisetyenziselwa ukufota ngokubanzi okanye usetyenziso lwevidiyo.

Okulandelayo, makhe sijonge umahluko ophambili phakathi kweelensi zekhamera kunye neelensi zokuskena umgca:

Ubude beFocal kunye noBunzulu beSithili

Iilensi zekhamera zihlala zinobude obufutshane befocal kunye nobunzulu obukhulu bentsimi, ezifanelekileyo ukuthwebula imifanekiso kwiimeko ezahlukeneyo, kubandakanya izinto, abantu, iindawo ezibukekayo, njl.njl.; iilensi zokuskena umgca zihlala ziyilelwe ubude obuthile befocal kunye nomgama wokusebenza kwizicelo ezithile zokuhlolwa kwemizi-mveliso.

Ukudubula umhlaba

Umgangatho womfanekiso

Iilensi zekhamera zihlala zenzelwe ukufota ngemifanekiso ekumgangatho ophezulu, kunye nomgangatho ophezulu wokuthatha imifanekiso kunye nokukwazi ukuphinda imibala;iilensi zokuskena umgcagxila kakhulu kwisisombululo esiphezulu, ukuphazamiseka okuphantsi kunye nemifanekiso ekhawulezayo, ikakhulu ukuhlangabezana neemfuno zokuhlolwa kwemizi-mveliso kunye nokucubungula imifanekiso.

Ukulungiswa kwesithuba

Iilensi zekhamera zihlala zine-aperture ehlengahlengiswayo ukulawula ubungakanani bokukhanya okungenayo kunye nobunzulu bentsimi; iilensi zokuskena umgca azidingi ukulungiswa kwe-aperture kuba iimeko zokusetyenziswa kwazo zihlala zifuna iimeko zokukhanya ezizinzileyo kunye nobunzulu be-focal.

ekhethekileyofukutya

Iilensi zekhamera zinokufuna ukuba nemisebenzi ekhethekileyo efana nokulwa nokushukuma, ukugxila ngokukhawuleza, ukungangeni manzi kunye nokuthintela uthuli ukuze zilungele iimeko ezahlukeneyo zokudubula kunye neemfuno zokudubula; iilensi zokuskena umgca azidingi le misebenzi ikhethekileyo, kwaye uyilo lwazo luya kujoliswa ngakumbi kwiimeko ezithile zesicelo semizi-mveliso.

2,Iyintoni impembelelo yomfanekiso welensi yokuskena umgca?

Isiphumo sokufota kwelensi yokuskena umgca sinxulumene neeparamitha zoyilo lwayo, umgangatho welensi, kunye nesenzi sokufota, kwaye sinokuchaphazeleka zezi zinto zilandelayo:

Ngokuphathelele umgangatho womfanekiso

Umgangatho womfanekiso welensi yokuskena umgca uchaphazeleka kakhulu luyilo lwe-optical kunye nomgangatho wezinto ezisetyenziswa yilensi.ilensi yokuskena umgcainokubonelela ngemifanekiso ecacileyo, ebukhali, engenasiphazamiso kwaye ivelise ngokuchanekileyo iinkcukacha zomntu ochaphazelekayo. Xa kuthelekiswa, ilensi ekumgangatho ophantsi inokuba neengxaki ezifana nokuphazamiseka kunye nokuphazamiseka, okuya kunciphisa umgangatho womfanekiso.

Iinkcukacha zokudubula

Ngokuphathelele isisombululo

Iilensi zokuskena umgca zihlala zinezisombululo eziphezulu kwaye zinokubamba imifanekiso eneenkcukacha ezityebileyo. Iilensi ezinezisombululo eziphezulu zinokubonelela ngemifanekiso ecolekileyo kwaye zifanelekile kwizicelo ezifuna izinto ezincinci okanye umlinganiselo ochanekileyo; iilensi ezinezisombululo eziphantsi zinokubamba imifanekiso efipheleyo kwaye zilahlekelwe ziinkcukacha ezithile.

Ngokuphathelele ingxolo kunye noluhlu olutshintshatshintshayo

Ingxolo kunye nobubanzi obuguqukayo belensi yokuskena imigca buchaphazela ngqo umgangatho womfanekiso. Ilensi yokuskena imigca esemgangathweni ophezulu inokubonelela ngemifanekiso engenangxolo iphantsi enobubanzi obukhulu obuguqukayo, igcina iinkcukacha kwiindawo eziqaqambileyo nezimnyama, iqinisekisa ukuchaneka kunye nobunyani bomfanekiso.

Ngokuphathelele ukucaca

Ukucaca komfanekiso welensi yokuskena umgca kunxulumene nezinto ezifana nobude belensi, umgama wento eguquguqukayo, kunye nesantya sokuhamba kwento. Ngokulungisa ubude bento egxile kuyo kunye nomgama wento yelensi, ukufota ngokucacileyo kwezinto ezikumgama owahlukeneyo kunokufezekiswa. Ukongeza, kwizinto ezihamba ngokukhawuleza, ilensi yokuskena umgca kufuneka ibe nophawu lokuphendula ngokukhawuleza ukuze kuthintelwe ukufiphala kwentshukumo.

Ngokuphathelele ukuveliswa kombala

Amandla okuvelisa imibala kwiilensi zokuskena umgca abaluleke kakhulu kwezinye izicelo, ezifana nomzi-mveliso wokuprinta, imifanekiso yezonyango, njl.ilensi yokuskena umgcainokubuyisela ngokuchanekileyo umbala neenkcukacha zombala zento efotwayo.

Iingcinga Zokugqibela:

Ukuba unomdla wokuthenga iintlobo ngeentlobo zeelensi zokujonga, ukuskena, iidrone, ikhaya elikrelekrele, okanye naluphi na olunye uhlobo lokusetyenziswa, sinazo izinto ozifunayo. Nxibelelana nathi namhlanje ukuze ufunde okungakumbi ngeelensi zethu kunye nezinye izixhobo.
