Izingxenye ze-Opticalbhekisela ezingxenyeni eziyinhloko zeizinhlelo zamehloezisebenzisa izimiso zokubona ukuze zenze imisebenzi ehlukahlukene njengokubuka, ukulinganisa, ukuhlaziya nokurekhoda, ukucubungula ulwazi, ukuhlolwa kwekhwalithi yesithombe, ukudluliswa kwamandla nokuguqulwa, futhi okuyingxenye ebalulekile yezingxenye eziyinhloko zamathuluzi okubona, imikhiqizo yokubonisa isithombe, kanye nokubonwayo. amadivaysi okugcina. Ngokuvumelana nokunemba nokuhlukaniswa kokusetshenziswa, kungahlukaniswa ngezingxenye zendabuko ze-optical kanye nezingxenye ze-optical ezinembayo. Izingxenye zendabuko ze-optical zisetshenziswa ikakhulukazi kukhamera yendabuko, isibonakude, isibonakhulu kanye neminye imikhiqizo yendabuko yokubona; Izingxenye ze-Optical Precision zisetshenziswa kakhulu kumafoni ahlakaniphile, amaphrojetha, amakhamera edijithali, amakhamera, amakhophi, izinsimbi zokubona, imishini yezokwelapha kanye namalensi okubona anembile ahlukahlukene.
Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokuthuthukiswa kwezinqubo zokukhiqiza, amafoni ahlakaniphile, amakhamera edijithali neminye imikhiqizo kancane kancane sekuyimikhiqizo ebalulekile yabathengi kubahlali, ukushayela imikhiqizo ye-optical ukwandisa izidingo zokunemba zezingxenye ze-optical.
Ngokombono wenkundla yesicelo sengxenye ye-optical global, amafoni ahlakaniphile namakhamera edijithali yizinto ezibaluleke kakhulu zokusebenza zengxenye ye-optical component. Isidingo sokuqapha ezokuphepha, amakhamera ezimoto, kanye namakhaya ahlakaniphile nakho kubeke phambili izidingo eziphakeme zokucaciswa kwekhamera, okungagcini nje ukwandisa isidingoopticalifilimu yelensi yamakhamera anencazelo ephezulu, kodwa futhi ikhuthaza ukuthuthukiswa kwemikhiqizo yokumboza yendabuko ibe yimikhiqizo yokumboza nge-optical coating enamamajini enzuzo enkulu.
Ukuthuthukiswa komkhakha
① ukushintshwa kwethrendi yesakhiwo somkhiqizo
Ukuthuthukiswa kwemboni yezingxenye ze-optical enembayo kungaphansi kwezinguquko esidingweni somkhiqizo ongezansi. Izingxenye ze-Optical zisetshenziswa kakhulu emikhiqizweni ye-optoelectronic efana namaphrojetha, amakhamera edijithali namathuluzi okubona anembile. Eminyakeni yamuva, ngokuthandwa okusheshayo kwamafoni ahlakaniphile, imboni yekhamera yedijithali iyonke ingene enkathini yokwehla, futhi isabelo sayo semakethe siye sashintshwa kancane kancane amafoni amakhamera anencazelo ephezulu. Igagasi lamadivayisi agqokekayo ahlakaniphile aholwa yi-Apple libe usongo olubulalayo emikhiqizweni yendabuko ye-optoelectronic eJapan.
Sekukonke, ukukhula okusheshayo kwesidingo sezokuphepha, izimoto, nemikhiqizo yama-smartphone kuqhubekisele phambili ukulungiswa kwesakhiwo somkhakha wezinto ezibonakalayo. Ngokulungiswa kwesakhiwo somkhiqizo ongezansi komfula wemboni yezithombe zikagesi, imboni yezingxenye ze-optical emaphakathi nochungechunge lwezimboni nakanjani izoshintsha indlela yokuthuthukiswa komkhiqizo, ilungise ukwakheka komkhiqizo, futhi isondele ezimbonini ezintsha ezifana namafoni ahlakaniphile. , izinhlelo zokuphepha, namalensi emoto.
②Ukushintsha kwesimo sokuthuthukiswa kobuchwepheshe
Isikhumuloimikhiqizo ye-optoelectronicathuthukela ekuqondeni kwamaphikseli aphezulu, azacile futhi ashibhile, okubeka phambili izidingo zobuchwepheshe eziphakeme zezingxenye ze-optical. Ukuze uvumelane nemikhuba enjalo yomkhiqizo, izingxenye ze-optical zishintshile ngokwezinto zokwakha kanye nezinqubo zobuchwepheshe.
(1) Ama-lens aspherical optical ayatholakala
I-imaging ye-lens eyindilinga ine-aberration, kulula ukubangela ubukhali kanye nokuguquguquka kwamaphutha, i-aspherical lens ingathola ikhwalithi ye-imaging engcono, ilungise ukuphambuka okuhlukahlukene, ithuthukise ikhono lokuhlonza uhlelo. Ingakwazi esikhundleni sezingxenye eziningi zamalensi ayindilinga ngengxenye eyodwa noma ezimbalwa zelensi ye-aspherical, yenza ukwakheka kwensimbi kube lula futhi kunciphise izindleko. Isibuko se-parabolic esivame ukusetshenziswa, isibuko se-hyperboloid nesibuko esiyi-elliptic.
(2) Ukusetshenziswa okubanzi kwamapulasitiki okukhanya
Izinto zokusetshenziswa eziyinhloko zezingxenye ze-optical ikakhulukazi ingilazi ye-optical, futhi ngokuthuthukiswa kobuchwepheshe bokuhlanganiswa kanye nokuthuthukiswa kobuchwepheshe bokucubungula, amapulasitiki optical athuthuke ngokushesha. Izinto ezibonakalayo zengilazi ye-optical yendabuko zibiza kakhulu, ubuchwepheshe bokukhiqiza nokucubungula kabusha buyinkimbinkimbi, futhi isivuno asiphezulu. Uma kuqhathaniswa nengilazi ye-optical, ama-optical plastics anezici ezinhle zenqubo yokubumba ipulasitiki, isisindo esilula, izindleko eziphansi nezinye izinzuzo, futhi asetshenziswe kabanzi ekuthwebuleni izithombe, ezindiza, ezempi, ezokwelapha, ezamasiko kanye nezemfundo zezinsimbi ezisetshenziswa umphakathi kanye nemishini.
Ngokombono wezicelo ze-lens optical, zonke izinhlobo zamalensi namalensi zinemikhiqizo yepulasitiki, engakhiwa ngokuqondile ngenqubo yokubumba, ngaphandle kokugaya okungokwesiko, ukugaya okuhle, ukupholisha nezinye izinqubo, ezifanele ikakhulukazi izingxenye ze-aspherical optical. Esinye isici sokusetshenziswa kwepulasitiki ye-optical ukuthi i-lens ingenziwa ngokuqondile ngesakhiwo sohlaka, ukwenza kube lula inqubo yokuhlanganisa, ukuqinisekisa ikhwalithi yomhlangano nokunciphisa izindleko zokukhiqiza.
Eminyakeni yamuva nje, ama-solvents asetshenziselwe ukusabalalisa kumapulasitiki okukhanya ukushintsha inkomba ye-refractive yezinto ezibonakalayo nokulawula izici zomkhiqizo kusukela esigabeni sempahla eluhlaza. Eminyakeni yamuva nje, abafuywayo baqala ukunaka ukusetshenziswa nokuthuthukiswa kwamapulasitiki optical, uhla lwesicelo salo lunwetshiwe kusukela ezingxenyeni ezibonakalayo ezibonakalayo kuya kumasistimu we-imaging optical, abakhiqizi basekhaya ohlelweni lokufakela optical ngokwengxenye noma konke ukusetshenziswa amapulasitiki okukhanya esikhundleni sengilazi ye-optical. Esikhathini esizayo, uma iziphambeko ezifana nokungazinzi kahle, inkomba ye-refractive ishintsha ngokushisa, nokumelana nokugqoka okungalungile kunganqotshwa, ukusetshenziswa kwamapulasitiki optical emkhakheni wezingxenye ze-optical kuzoba kubanzi kakhulu.
