一,Wisigqoko siwukuhlanekezela kwelensi esithombeni?
Ukuhlanekezelwa kwelensi ezithombeni kubhekisela ekuphambukeni kokubona okwenzekayo lapho ilensi yekhamera yehluleka ukukhiqiza kabusha ngokunembile isithombe sesihloko esithwetshulwayo.Lokhu kubangela isithombe esihlanekezelwe okungenzeka sinwetshiwe noma sicindezelwe, kuye ngohlobo lokuhlanekezela.Kunezinhlobo ezimbili eziyinhloko zokuhlanekezela amalensi:ukuhlanekezela komgqomofuthiukuhlanekezela kwe-pincushion.
Ukuhlanekezela komgqomo kwenzeka lapho imigqa eqondile eduze konqenqema lwesithombe ibonakala igobela ngaphandle, idala umphumela oqhumayo.Ngakolunye uhlangothi, ukuhlanekezela kwe-Pincushion kwenzeka lapho imigqa eqondile eduze konqenqema lwesithombe ibonakala igobela ngaphakathi, idala umphumela ompintshiwe.
Ukuhlanekezelwa kwelensi kungenzeka ngenxa yezici ezihlukahlukene njengokuklanywa nokwakhiwa kwelensi, i-engeli yokubuka, nebanga phakathi kwekhamera nesihloko.Izinga lokuhlanekezela lingahluka kuye ngokuthi ilensi ethile esetshenziswayo kanye nezilungiselelo ezisetshenziswa umthwebuli wezithombe.
Ngenhlanhla, ukuhlanekezela kwelensi kuvame ukulungiswa ngokusebenzisa amasu okucubungula ngemva kokucubungula noma ngokusebenzisa isofthiwe ekhethekile eklanyelwe ukulungisa ukuhlanekezela kwamalensi.Kodwa-ke, kuhlala kuhle kakhulu ukunciphisa ukuhlanekezela kwamalensi ngokusebenzisa amalensi ekhwalithi ephezulu kanye nokufaka uzimele amashothi akho ngokucophelela ukuze ugweme ukuhlanekezela ngokweqile.
二,Umehluko wokuhlanekezela phakathiaamalensi ayindilinga namalensi ayindilinga.
Amalensi aspherical namalensi ayindilinga ayizinhlobo zamalensi okubona asetshenziswa kumakhamera, izibonakude, amamicroscopes, nezinye izinsimbi zokubona.
Amalensi ayindilingaibe nendawo egobile emise okwengxenye yendilinga, futhi iwuhlobo olujwayeleke kakhulu lwamalensi.Kodwa-ke, angakwazi ukwethula ukujika kokubona okufana ne-spherical aberration, coma, nokuhlanekezela, ikakhulukazi uma kusetshenziswa ezindaweni ezinkulu noma kumalensi ama-engeli abanzi.
Amalensi aspherical, ngakolunye uhlangothi, inobuso obungeyona i-spherical eklanyelwe ukulungisa lokhu kuphambuka.Lokhu kuvumela izithombe ezibukhali ezinokugqama okungcono nokuhlanekezela okuncishisiwe, ikakhulukazi emaphethelweni ozimele.Amalensi aspherical avame ukusetshenziswa kumalensi aphezulu, futhi angatholakala kuwo womabili amalensi aphambili nasondezayo.
Sekukonke, ukusetshenziswa kwamalensi aspherical kungasiza ekuthuthukiseni ukusebenza kokubona kwelensi, ikakhulukazi mayelana nokunciphisa ukuhlanekezela nokunye ukuphazamiseka.Kodwa-ke, amalensi aspherical ngokuvamile abiza kakhulu ukuwakhiqiza kunamalensi ayindilinga, okungawenza abize kakhulu kubathengi.
三,Wisigqoko siyilensi ye-engeli ebanzi ephansi yokuhlanekezela?
A i-lens ye-engeli ebanzi yokuhlanekezela okuphansiiwuhlobo lwamalensi ekhamera oluvumela inkambu ebanzi yokubuka kunelensi evamile kuyilapho kunciphisa noma kususa ukuhlanekezela okungenzeka ngamalensi ane-engeli ebanzi.
Amalensi ane-engeli ebanziinobude bokugxila obufushane kunamalensi ajwayelekile futhi ingathwebula isigcawu esiningi ngohlaka olulodwa, izenze zidume ngokuma kwezwe, izakhiwo, nezithombe zangaphakathi.Nokho, ngenxa ye-engeli ebanzi yokubuka, zingaphinda zikhiqize ukuhlanekezela, okungase kubangele ukuthi imigqa eqondile ibonakale igobile noma izinto ezibonakala zeluliwe noma zihlanekezelwe.
Amalensi ane-engeli ebanzi ahlanekezelazenzelwe ukunciphisa noma ukuqeda lokhu kuhlanekezela, okuvumela ukumelwa okunembe kakhudlwana nokungokoqobo kwesigcawu.Lawa ma lens ngokuvamile asetshenziswa abathwebuli bezithombe abangochwepheshe abadinga inkambu yokubuka ebanzi ngaphandle kokufaka engozini ikhwalithi yesithombe noma ukunemba.
四,Wisigqoko yizicelo eziyinhloko ze-lens ye-M12 ephansi yokuhlanekezela?
II-lens ye-M12 ephansi yokuhlanekezelaisetshenziswa kakhulu ekuboneni komshini nasezinhlelweni zokubona ngekhompyutha, ikakhulukazi kumakhamera nasezinhlelweni zezithombe ezidinga izithombe zekhwalithi ephezulu ezinokuhlanekezelwa okuncane.Nazi ezinye zezinhlelo zokusebenza eziyinhloko zamalensi aphansi we-M12:
I-Industrial Automation: Amalensi aphansi we-M12 ahlanekezela asetshenziswa ezinhlelweni ezishintshayo zezimboni ukuze kuthathwe izithombe ezicacile nezinembile zezinto ezinqubweni zokukhiqiza.
Amarobhothi: Izinhlelo zokusebenza zamarobhothi zivame ukusebenzisa amalensi okuhlanekezela aphansi angu-M12 ukuze uthole amasistimu wokuzwa okubukwayo kanye neziqondiso ezidinga ukunemba okuphezulu nokunemba.
Ezokuphepha Nokugada: Amalensi aphansi we-M12 ahlanekezela ngokuvamile asetshenziswa kumakhamera okuphepha nezinhlelo zokugada ukuze athwebule izithombe ezicacile nezinembile zabantu nezinto.
Ukufanekisa Kwezokwelapha: Amalensi aphansi we-M12 ahlanekezela aphinde asetshenziswe ezinhlelweni zezithombe zezokwelapha ngezinjongo zokuxilonga nokucwaninga.
Ezezimoto: Amalensi aphansi we-M12 ahlanekezela asetshenziswa ezinhlelweni ezithuthukisiwe zokusiza abashayeli (ADAS) ezimotweni, njengezinhlelo zokuxwayisa ngokuhamba komzila kanye nezinhlelo zokugwema ukushayisana.
Sekukonke, i-M12 low distortion lens iyithuluzi elisebenza ngezindlela eziningi lanoma yiluphi uhlelo lokusebenza oludinga ukuthwebula izithombe kwekhwalithi ephezulu nokuhlanekezela okuncane.
