I-Matshini yoMbono weLensiNgaba i-lens yekhamera yeshishini eyilwe ngokukhethekileyo iinkqubo zomatshini. Umsebenzi wayo ophambili kukwenza iprojekhthi yomfanekiso wento ekufotwa kwi-Solsor yekhamera yokuqokelelwa kwemifanekiso ezenzekelayo, ukuqhubekisa kunye nohlalutyo.
Isetyenziswe ngokubanzi kwimimandla emininzi enjengemilinganiselo echanekileyo yokuchaneka, iNdibano yokuSebenza, yokuHlola, kunye nokuHamba.
1,Umgaqo we-lens yombono
Imigaqo ye-lenses yombono yomatshini yayibandakanya ukucinga okuqhubekayo, amachwephesha ejometri, amayeza emnyama kunye nezinye iindawo, kubandakanya ubude bokugxila, indawo yokujonga, i-Aperture kunye nezinye iiparamitha zentsebenzo. Emva koko, masifunde ngakumbi malunga nemigaqo-siseko yeelensi zombono wamatshini.
Imigaqo yengcinga yokukhanya.
Umgaqo wokucinga ngengcinga kukuba iilensi zigxile kwinzwayo kwi-ENS (njengamaqela eelensi zendawo kunye neelensi zendawo) ukuvelisa umfanekiso wedijithali yento.
Isikhundla kunye nesithuba seqela le-lens kwiNdlela yokuKhangela liza kuchaphazela ubude obujolise kubo, indawo yokujonga, isisombululo kunye nezinye iiparamitha zentsebenzo zelensi.
Imigaqo-siseko ye-geometric.
Umgaqo-siseko we-geometric off yelensi kukujonga ukukhanya okubonakalayo kwinto kwinzwa phantsi kwemiqathango ebonakalisayo kunye nokuvuselelwa kwanelisekile.
Kule nkqubo, kubalulekile ukoyisa ukungangqinelani, ukugqwetha, ukungangqinelani kunye nezinye iingxaki zelensi yokuphucula umgangatho wokucinga.
Imigaqo-siseko ye-optics yomzimba.
Xa ukuhlalutya i-lens icinga ukusebenzisa imigaqo-siseko ye-optics ye-optics, kuyimfuneko ukuthathela ingqalelo indalo kunye nokuphazamiseka kwe-phenomena yokukhanya. Oku kuyakuchaphazela iiparamitha zentsebenzo ezinje ngesigqibo, umahluko kwiilensi zinokujongana nokucingisisa kunye nokusasaza imiba kunye nokuphucula umgangatho.
Uphawu lombono
Ubude obujolise kubude bendawo yokuhlala.
Ubude obujolise kwilensi bubhekisa kumgama phakathi kwento kunye nelensi. Igqiba ubungakanani bendawo ye-lens yelensi, oko kukuthi, uluhlu lwemifanekiso enokuthi ibambe ikhamera.
Ubude obungaphantsi kobungakanani bokugxila, abacimi bomlomo, kunye nokukhula komfanekiso; Owona mfutshane ubude obujolise kuyo, ebanzi yendawo yokujonga, kunye nokukhuliswa komfanekiso.
I-aperture kunye nobunzulu bentsimi.
I-aperture ngumngxunya ohlengahlengisiweyo kwilensi elawula ubungakanani bokukhanya okudlula kwilensi. Ubungakanani be-aperture bunokuhlengahlengisa ubunzulu bentsimi (oko kukuthi, uluhlu olucacileyo lokucinga), oluchaphazela ukukhanya komfanekiso kunye nomgangatho wengcinga.
Elona lizwe likhulu, kokukhanya ngakumbi kungena kunye nobunzulu bentsimi; Incinci i-aperture, ukukhanya okuncinci kungena kwaye kubunzulu bentsimi.
Isisombululo.
Isisombululo esibhekisa kumgama omncinci ukuba iilensi zinokusombulula, kwaye zisetyenziselwa ukulinganisa ukucaca komfanekiso welensi. Ukuphakama kwesisombululo, kungcono kumgangatho womfanekiso welensi.
Ngokubanzi, xa sele ihambelana, isisombululo seI-Matshini yoMbono weLensikufuneka angqinelane neepikseli zenzwa, ukuze intsebenzo yenkqubo yelensi isetyenziswe ngokupheleleyo.
2,Umsebenzi we-lens yombono
Iinkqubo zombono zoomatshini zisetyenziswa ngokubanzi kwimveliso ye-elektroniki, imizi-mveliso kunye namanye amasimi. Njengoko eyona nto ibalulekileyo yenkqubo yombono, iilensi zombono zoomatshini zinefuthe lokuthatha isigqibo kwintsebenzo nakwiimpembelelo zenkqubo.
Imisebenzi ephambili yelensi yombono yomatshini imi ngolu hlobo lulandelayo:
FOrm umfanekiso.
Inkqubo yombono iqokelela ulwazi malunga nento ekujoliswe kuyo ngelensi, kwaye ilensi igxile ukukhanya kwesaziso sekhamera ukwenza umfanekiso ocacileyo.
Imisebenzi yeLensi yombono
Ibonelela ngendawo yokujonga.
Intsimi yokujonga iilensi ichaza ubungakanani kunye nendawo yokujonga into ekujoliswe kuyo ikhamera iya kuqokelela. Ukukhetha kwecandelo lembono kuxhomekeke kubude obujolise kwilensi kunye nobungakanani be-semer yekhamera.
Lawula ukukhanya.
Uninzi lwamatshini wombono lube nohlengahlengiso lohlengahlengiso olulawula isixa sokukhanya okungena kwikhamera. Lo msebenzi ubalulekile ekufumaneni imifanekiso esemgangathweni phantsi kweemeko ezahlukeneyo zokukhanyisa.
Chonga isigqibo.
Ilensi elungileyo inokubonelela ngemifanekiso ecacileyo, ekumgangatho ophezulu enenkcukacha eziphezulu, ezibaluleke kakhulu ekufumaneni ngokuchanekileyo kunye nokuchongwa kwezinto.
I-lens lungisa lokulungiswa.
Xa uyilo loomatshini umbono womatshini, ukugqwetha kuya kulungiswa ukuze iilensi zifumane iziphumo eziyinyani nezichanekileyo ngexesha lokuqhubekiswa komfanekiso.
Ukucinga okunzulu.
Ezinye iilensi eziphambili zinokubonelela ngolwazi olunzulu, olubaluleke kakhulu kwimisebenzi enjengokufunyanwa kwento, ukwamkelwa, kunye nokuma.
Iingcinga zokugqibela:
I-Chuangan iqhube uyilo lwangaphambili kunye nemveliso yeIminwe yombono wamatshini, esetyenziswa kuwo onke amabakala eenkqubo zombono zomatshini. Ukuba unomdla okanye unezidingo ze-lenses yombono, nceda uqhagamshelane nathi ngokukhawuleza.
