Cov khoom siv kho qhov muagxa mus rau cov khoom tseem ceeb ntawmcov tshuab kho qhov muaguas siv cov ntsiab cai kho qhov muag los ua ntau yam haujlwm xws li kev soj ntsuam, kev ntsuas, kev tshuaj xyuas thiab kev kaw, kev ua cov ntaub ntawv, kev ntsuas qhov zoo ntawm cov duab, kev xa hluav taws xob thiab kev hloov pauv, thiab yog ib feem tseem ceeb ntawm cov khoom tseem ceeb ntawm cov cuab yeej kho qhov muag, cov khoom tso saib duab, thiab cov khoom siv khaws cia kho qhov muag. Raws li qhov tseeb thiab kev siv kev faib tawm, nws tuaj yeem muab faib ua cov khoom siv kho qhov muag ib txwm muaj thiab cov khoom siv kho qhov muag raug. Cov khoom siv kho qhov muag ib txwm muaj feem ntau siv rau hauv lub koob yees duab ib txwm muaj, lub tsom iav, lub tshuab microscope thiab lwm yam khoom siv kho qhov muag ib txwm muaj; Cov khoom siv kho qhov muag raug feem ntau siv rau hauv cov xov tooj ntse, cov projectors, cov koob yees duab digital, cov koob yees duab, cov tshuab luam ntawv, cov cuab yeej kho qhov muag, cov khoom siv kho mob thiab ntau yam iav kho qhov muag raug.
Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho ntawm cov txheej txheem tsim khoom, cov xov tooj ntse, cov koob yees duab digital thiab lwm yam khoom tau maj mam dhau los ua cov khoom siv tseem ceeb rau cov neeg nyob hauv, tsav cov khoom siv kho qhov muag kom nce qhov kev xav tau ntawm cov khoom siv kho qhov muag.
Los ntawm qhov kev xav ntawm lub ntiaj teb kev siv cov khoom siv kho qhov muag, cov xov tooj ntse thiab cov koob yees duab digital yog qhov tseem ceeb tshaj plaws rau cov khoom siv kho qhov muag. Qhov kev thov rau kev saib xyuas kev ruaj ntseg, lub koob yees duab tsheb, thiab cov tsev ntse kuj tau muab cov kev xav tau siab dua rau kev pom tseeb ntawm lub koob yees duab, uas tsis yog tsuas yog ua rau muaj kev thov raukho qhov muagzaj duab xis lens rau cov koob yees duab siab, tab sis kuj txhawb kev hloov kho dua tshiab ntawm cov khoom siv kho qhov muag ib txwm mus rau cov khoom siv kho qhov muag nrog cov nyiaj tau los ntau dua.
Kev loj hlob ntawm kev lag luam
① qhov kev hloov pauv ntawm cov qauv khoom
Kev txhim kho ntawm kev lag luam cov khoom siv kho qhov muag precision yog raws li kev hloov pauv ntawm qhov kev thov khoom downstream. Cov khoom siv kho qhov muag feem ntau yog siv rau hauv cov khoom optoelectronic xws li projectors, digital koob yees duab thiab cov cuab yeej kho qhov muag precision. Nyob rau hauv xyoo tas los no, nrog rau kev nrov nrov ntawm cov xov tooj ntse, kev lag luam koob yees duab digital tag nrho tau nkag mus rau lub sijhawm poob qis, thiab nws cov feem ntawm kev ua lag luam tau maj mam hloov los ntawm cov xov tooj koob yees duab siab. Cov nthwv dej ntawm cov khoom siv ntse hnav uas coj los ntawm Apple tau ua rau muaj kev hem thawj rau cov khoom siv optoelectronic ib txwm muaj hauv Nyiv.
Zuag qhia tag nrho, kev loj hlob sai ntawm kev thov rau kev ruaj ntseg, tsheb, thiab cov khoom siv xov tooj ntse tau tsav tsheb kev hloov kho cov qauv ntawm kev lag luam khoom siv kho qhov muag. Nrog rau kev hloov kho ntawm cov qauv khoom lag luam downstream ntawm kev lag luam photoelectric, kev lag luam khoom siv kho qhov muag hauv nruab nrab ntawm cov saw hlau kev lag luam yuav tsum hloov pauv kev coj ua ntawm kev tsim khoom, kho cov qauv khoom, thiab txav mus ze rau cov lag luam tshiab xws li xov tooj ntse, cov txheej txheem kev ruaj ntseg, thiab cov iav tsheb.
② Kev hloov pauv ntawm kev txhim kho thev naus laus zis
Chaw nres nkojcov khoom siv hluav taws xobtab tom tsim kho mus rau hauv kev coj ntawm cov pixels siab dua, nyias dua thiab pheej yig dua, uas tso tawm cov kev cai siab dua rau cov khoom siv kho qhov muag. Txhawm rau kom hloov kho rau cov qauv khoom lag luam zoo li no, cov khoom siv kho qhov muag tau hloov pauv hauv cov ntaub ntawv thiab cov txheej txheem kev siv tshuab.
(1) Muaj cov iav tsom iav aspherical optical
Cov duab ntawm lub lens spherical muaj qhov tsis zoo, yooj yim ua rau qhov tsis zoo ntawm qhov ntse thiab kev hloov pauv, lub lens aspherical tuaj yeem tau txais cov duab zoo dua, kho ntau yam kev tsis zoo, txhim kho lub peev xwm txheeb xyuas qhov system. Nws tuaj yeem hloov ntau qhov ntawm lub lens spherical nrog ib lossis ntau qhov ntawm lub lens aspherical, ua kom yooj yim rau cov qauv ntsuas thiab txo tus nqi. Feem ntau siv daim iav parabolic, daim iav hyperboloid thiab daim iav elliptic.
(2) Kev siv dav ntawm cov yas kho qhov muag
Cov khoom siv tseem ceeb ntawm cov khoom siv kho qhov muag feem ntau yog iav kho qhov muag, thiab nrog kev txhim kho ntawm cov thev naus laus zis synthesis thiab kev txhim kho ntawm cov thev naus laus zis ua tiav, cov yas kho qhov muag tau tsim kho sai. Cov khoom siv iav kho qhov muag ib txwm kim dua, cov thev naus laus zis tsim khoom thiab rov ua dua tshiab yog qhov nyuaj, thiab cov txiaj ntsig tsis siab. Piv nrog cov iav kho qhov muag, cov yas kho qhov muag muaj cov yam ntxwv zoo ntawm cov txheej txheem yas molding, lub teeb yuag, tus nqi qis thiab lwm yam zoo, thiab tau siv dav hauv kev thaij duab, kev tsav dav hlau, tub rog, kev kho mob, kev coj noj coj ua thiab kev kawm ntawm cov cuab yeej kho qhov muag pej xeem thiab cov khoom siv.
Los ntawm qhov kev xav ntawm kev siv lub lens kho qhov muag, txhua yam lens thiab lens muaj cov khoom yas, uas tuaj yeem tsim ncaj qha los ntawm cov txheej txheem molding, tsis muaj kev sib tsoo ib txwm muaj, kev sib tsoo zoo, kev txhuam thiab lwm yam txheej txheem, tshwj xeeb tshaj yog haum rau cov khoom siv kho qhov muag aspherical. Lwm qhov tshwj xeeb ntawm kev siv cov yas kho qhov muag yog tias lub lens tuaj yeem tsim ncaj qha nrog cov qauv thav duab, ua kom yooj yim rau cov txheej txheem sib dhos, xyuas kom meej tias qhov zoo ntawm kev sib dhos thiab txo cov nqi tsim khoom.
Nyob rau hauv xyoo tas los no, cov kuab tshuaj tau siv los diffuse rau hauv cov yas kho qhov muag kom hloov cov refractive index ntawm cov khoom siv kho qhov muag thiab tswj cov yam ntxwv ntawm cov khoom los ntawm cov khoom siv raw. Nyob rau hauv xyoo tas los no, lub teb chaws kuj pib them sai sai rau daim ntawv thov thiab kev txhim kho ntawm cov yas kho qhov muag, nws daim ntawv thov tau nthuav dav los ntawm cov khoom pob tshab kho qhov muag mus rau cov duab kho qhov muag, cov chaw tsim khoom hauv teb chaws hauv lub cev kho qhov muag ib feem lossis txawm tias tag nrho siv cov yas kho qhov muag es tsis txhob siv iav kho qhov muag. Nyob rau hauv lub neej yav tom ntej, yog tias cov qhov tsis zoo xws li kev ruaj khov tsis zoo, refractive index hloov pauv nrog qhov kub thiab txias, thiab kev tiv thaiv kev hnav tsis zoo tuaj yeem kov yeej, daim ntawv thov ntawm cov yas kho qhov muag hauv thaj chaw ntawm cov khoom siv kho qhov muag yuav dav dua.
