Amalensi aphansi okuphambukaziwuhlobo olukhethekile lwamalensi emkhakheni wezithombe kanye nokuthwebula izithombe okukhanya. Zibonakala ngekhono lokunciphisa noma ukunciphisa ukuhlanekezela ngesikhathi senqubo yokuthwebula izithombe, ngaleyo ndlela zinikeze imiphumela yokuthwebula engokoqobo, enembile nemvelo. Ngokuvamile zisetshenziswa emikhakheni edinga ukunemba okuphezulu kwesithombe.
1.Yimiphi imiklamo ekhethekile yamalensi aphansi okuphambuka?
Amalensi aphansi ahlukanisayo ngokuvamile asebenzisa imiklamo ekhethekile yelensi nezinto ezibonakalayo. Lo mklamo welensi ungagcina imigqa eqondile esithombeni njengemigqa eqondile nezindilinga njengezindilinga, ngaleyo ndlela uthole isithombe esingokoqobo nesinembile.
Ekuklanyweni kwe-optical, izici ezilandelayo ziyizinto ezibalulekile okufanele uzicabangele ngamalensi aphansi okuphambuka:
(1)Ukukhetha izinto
Khetha izinto nezinto ezinezici ezinhle kakhulu zokukhanya, njengeelensi ezikhethekile ze-aspherical, amalensi ahlanganisiwe, njll., ukuze unciphise imiphumela yokuhlakazeka, ukuphazamiseka kwe-chromatic, njll. ekuphazamisekeni kwesistimu yokukhanya, ngaleyo ndlela kuthuthukiswe ikhwalithi yokuthwebula izithombe zelensi.
(2)Umklamo we-Optical
Ngesikhathi senqubo yokuklama, kubalulekile ukucabangela ngokuphelele nokuthuthukisa izinkomba zokusebenza kwelensi, njengokuxazulula, ukuhlanekezela kokukhanya, ukuhlakazeka, ukuphambuka kwe-chromatic, njll., ukunciphisa noma ukuqeda ukuhlanekezela, ukuze kufezwe umphumela omuhle kakhulu wokuthwebula izithombe.
Ngesikhathi esifanayo, klama isakhiwo selensi kanye nokulandelana kokuhlela izingxenye, okuhlanganisa inombolo, ukugoba, isikhala kanye nezinye izinhlaka zamalensi. Ukwakheka kwesakhiwo okunengqondo nakho kunganciphisa ngempumelelo ukuphambuka.
Ilensi yokuhlanekezela okuphansi inikeza isithombe sangempela
(3)Izindlela zokunxephezela
Dizayina futhi wengeze izinto ezikhethekile zokunxephezela ukulungisa ukuphambuka okungekuhle, njenge-aspherical lens, ama-gradient refractive index lens, njll. Lezi zinto zingalungisa izinhlobo ezahlukene zokuphambuka futhi zithuthukise ikhwalithi yokuthwebula izithombe zelensi.
2.Yiziphi izici ezivelele zamalensi aphansi okuphambuka?
Uma kuqhathaniswa namalensi ajwayelekile,amalensi okuphambuka okuphansibanezici ezilandelayo ezivelele:
(1)Mizithombe ezinembile kakhulu
Amalensi aphansi okuphambuka anganikeza izithombe ezinembile nezingokoqobo, agweme ukugoba noma ukuphambuka emaphethelweni esithombe, okwenza isithombe sicace futhi sinembile.
Isithombe esinembile ngaphandle kokuphazamiseka
(2)Ukusebenza okungcono kokukhanya
Amalensi aphansi okuphambuka asebenza kangcono ezinkombeni zokusebenza ezahlukahlukene zokukhanya, njengokulungiswa, ukuhlakazeka kanye namakhono okulawula ukuphambuka kwe-chromatic, okwenza imiphetho yesithombe icace futhi imininingwane ibe mihle, kuyilapho kuthuthukiswa amakhono okukhiqiza imibala, okwenza imibala yesithombe inembe kakhudlwana futhi ibe ngokoqobo.
(3)Umbono omkhulu kanye namakhono okulungisa i-geometric
Amalensi aphansi okuphambukaziyinkimbinkimbi kakhulu ekwakhiweni futhi zingalungisa kangcono ubudlelwano bombono kanye nobejiyometri besithombe, zigcine ubuqiniso bemigqa kanye nezimo esithombeni.
(4)Kufanelekela izinkambu zochwepheshe zezithombe nokulinganisa
Amalensi aphansi asetshenziswa kabanzi ekuthwebuleni izithombe zobungcweti, ukumaka nokuhlola kanye neminye imikhakha, njengezithombe zezakhiwo, ukuhlela amadolobha, ukudweba imephu kanye nezinye izigcawu ezidinga ukunemba okuphezulu kwesithombe kanye nokunemba kwesimo sejometri.
Kusetshenziswa kabanzi emikhakheni yobungcweti
(5)Thuthukisa ulwazi lomsebenzisi
Ngenxa yokuphazamiseka okuncane,amalensi okuphambuka okuphansiinganikeza okuhlangenwe nakho okubonakalayo okungokwemvelo nokungokoqobo lapho kudutshulwa amavidiyo nezithombe, okwenza izithombe zikhange futhi zijabulise kakhudlwana.
Imicabango Yokugcina:
Uma unesifiso sokuthenga izinhlobo ezahlukene zamalensi okuqapha, ukuskena, ama-drones, ikhaya elihlakaniphile, noma olunye uhlobo lokusetshenziswa, sinalokho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngamalensi ethu nezinye izesekeli.
