一,WKuyini ukuphambuka kwelensi ku-Photograph?
Ukuphambuka kwelensi ekuthwebuleni izithombe kubhekisela ekuphambukeni kokukhanya okwenzeka lapho ilensi yekhamera yehluleka ukukhiqiza kabusha ngokunembile isithombe somuntu othwetshulwa isithombe. Lokhu kuphumela esithombeni esiphambukile esinwetshiwe noma esicindezelwe, kuye ngohlobo lokuphambuka. Kunezinhlobo ezimbili eziyinhloko zokuphambuka kwelensi:ukuphambuka kwebharelifuthiukuhlanekezela kwe-pincushion.
Ukuphambuka kwebhareli kwenzeka lapho imigqa eqondile eduze kwemiphetho yesithombe ibonakala igoba ngaphandle, okudala umphumela wokukhukhumala. Ukuphambuka kwe-Pincushion, ngakolunye uhlangothi, kwenzeka lapho imigqa eqondile eduze kwemiphetho yesithombe ibonakala igoba ngaphakathi, okudala umphumela ocindezelwe.
Ukuphambuka kwelensi kungenzeka ngenxa yezici ezahlukahlukene njengokwakheka nokwakhiwa kwelensi, i-engeli yokubuka, kanye nebanga phakathi kwekhamera nomuntu oqokiwe. Izinga lokuphambuka lingahluka kuye ngelensi ethile esetshenziswayo kanye nezilungiselelo ezisetshenziswa ngumthwebuli wezithombe.
Ngenhlanhla, ukuphambuka kwelensi kungalungiswa ngokusebenzisa amasu okucubungula ngemuva noma ngokusebenzisa isofthiwe ekhethekile eyenzelwe ukulungisa ukuphambuka kwelensi. Kodwa-ke, kungcono ngaso sonke isikhathi ukunciphisa ukuphambuka kwelensi ngokusebenzisa amalensi asezingeni eliphezulu nokuhlela izithombe zakho ngokucophelela ukuze ugweme ukuphambuka ngokweqile.
二,Umehluko ekuhlanekezelweni phakathiaamalensi ayindilinga namalensi ayindilinga.
Amalensi e-aspherical namalensi ayindilinga ayizinhlobo zamalensi optical asetshenziswa kumakhamera, kumateleskopu, kumamicroscope, nakwezinye izinsimbi zokubona.
Amalensi ayisiyingizinobuso obugobile obufana nengxenye yesiyingi, futhi ziwuhlobo oluvame kakhulu lwelensi. Kodwa-ke, zingaletha ukuphambuka kokukhanya okufana nokuphambuka kwesiyingi, i-coma, kanye nokuphambuka, ikakhulukazi uma zisetshenziswa ezindaweni ezinkulu noma kumalensi ane-wide-angle.
Amalensi ajikelezayoNgakolunye uhlangothi, zinobuso obungesiyindilinga obuklanyelwe ukulungisa lokhu kuphazamiseka. Lokhu kuvumela izithombe ezibukhali ezinokungafani okungcono kanye nokuhlanekezela okuncishisiwe, ikakhulukazi emaphethelweni ohlaka. Amalensi e-aspherical avame ukusetshenziswa kumalensi aphezulu, futhi angatholakala kokubili kumalensi e-prime kanye ne-zoom.
Sekukonke, ukusetshenziswa kwamalensi aspherical kungasiza ekuthuthukiseni ukusebenza kwelensi, ikakhulukazi maqondana nokunciphisa ukuphambuka kanye nokunye ukuphazamiseka. Kodwa-ke, amalensi aspherical ngokuvamile abiza kakhulu ukuwakhiqiza kunamalensi ayindilinga, okungenza abize kakhulu kubathengi.
三,WIngabe ilensi yokuphambuka okuphansi okune-angle ebanzi?
A ilensi yokuphambukisa ephansi ene-engeli ebanziuhlobo lwelensi yekhamera evumela insimu ebanzi yokubuka kunelensi ejwayelekile ngenkathi inciphisa noma isusa ukuphambuka okungenzeka ngamalensi ane-angle ebanzi.
Amalensi ane-engeli ebanziZine-focal length emfushane kune-lens ejwayelekile futhi zingathwebula indawo eningi kufreyimu eyodwa, okwenza zithandeke kakhulu ezindaweni, ezakhiweni, kanye nezithombe zangaphakathi. Kodwa-ke, ngenxa ye-engeli ebanzi yokubuka, zingadala nokuphambuka, okungabangela imigqa eqondile ebonakala igobile noma izinto ezibonakala zinwetshiwe noma ziphambukile.
Amalensi e-wide-angle aphansi ahlanekezelwe kahlezenzelwe ukunciphisa noma ukuqeda lokhu kuhlanekezela, okuvumela ukumelwa okunembile nokungokoqobo kwendawo. Lawa malensi ngokuvamile asetshenziswa abathwebuli bezithombe abangochwepheshe abadinga insimu ebanzi yokubuka ngaphandle kokubeka engcupheni ikhwalithi yesithombe noma ukunemba.
四,WIyini ukusetshenziswa okuyinhloko kwelensi ye-M12 low distortion?
IIlensi yokuphambuka okuphansi ye-M12ivame ukusetshenziswa ezinhlelweni zokubona komshini kanye nezinhlelo zokubona zekhompyutha, ikakhulukazi kumakhamera nezinhlelo zokuthwebula izithombe ezidinga izithombe ezisezingeni eliphezulu ezinokuphazamiseka okuncane. Nazi ezinye zezinhlelo zokusebenza eziyinhloko zamalensi e-M12 aphansi okuphambuka:
I-Automatio Yezimbonin: Amalensi e-M12 aphansi okuphambuka asetshenziswa ezinhlelweni zokwenza izinto ngokuzenzakalela kwezimboni ukuze kuthwetshulwe izithombe ezicacile nezinembile zezinto ezinqubweni zokukhiqiza.
Amarobhothi: Izinhlelo zokusebenza zamarobhothi zivame ukusebenzisa amalensi e-M12 aphansi okuphambuka ukuze kutholakale izinhlelo zokuzwa nokuqondisa ezidinga ukunemba okuphezulu nokunemba.
Ukuphepha NokuqaphaAmalensi e-M12 aphansi okuphambuka avame ukusetshenziswa kumakhamera okuphepha kanye nezinhlelo zokuqapha ukuze kuthwetshulwe izithombe ezicacile nezinembile zabantu nezinto.
Izithombe ZezokwelaphaAmalensi e-M12 aphansi okuphambuka asetshenziswa nasezinhlelweni zezithombe zezokwelapha ngezinjongo zokuxilonga nokucwaninga.
Izimoto: Amalensi e-M12 aphansi okuphambuka asetshenziswa ezinhlelweni zokusiza abashayeli ezithuthukisiwe (i-ADAS) zezimoto, njengezinhlelo zokuxwayisa ukuhamba komgwaqo kanye nezinhlelo zokugwema ukushayisana.
Sekukonke, ilensi ye-M12 low distortion iyithuluzi elisebenziseka kalula kunoma yiluphi uhlelo lokusebenza oludinga izithombe zekhwalithi ephezulu kanye nokuphambuka okuncane.
