Kuti uve nechokwadi chekuti lens inogona kupa yemhando yepamusoro mifananidzo uye yakavimbika kuita mune chaiyo application mamiriro, zvinodikanwa kuita ongororo dzakakodzera pane lens. Saka, ndedzipi nzira dzekuongororamichina yekuona lenzi? Muchikamu chino, tichadzidza maitiro ekuongorora mashini ekuona lenzi.
Maitiro ekuongorora mashini ekuona lenzi
Ndedzipi nzira dzekuongorora dzemashini ekuona lenzi?
Iko kuongororwa kwemashini ekuona lenzi inoda kufunga zvakawanda zvematanho ekuita uye hunhu, uye inoda kuitwa pasi pekushanda kwehunyanzvi michina uye nyanzvi kuona kuti mhedzisiro yekuongorora ndeyechokwadi uye inoshanda.
Idzi ndidzo nzira huru dzekuongorora:
1.Munda wekuona bvunzo
Munda wekuona lens unosarudza saizi yenzvimbo iyo optical system inogona kuona, uye kazhinji inogona kuongororwa nekuyera dhayamita yemufananidzo wakaumbwa nelenzi pane yakatarwa kureba.
2.Distortion test
Distortion inoreva deformation inoitika kana lenzi yagadzira chinhu chaicho pandege yekufungidzira. Kune marudzi maviri makuru: mbiya kukanganisa uye pincushion distortion.
Ongororo inogona kuitwa nekutora mifananidzo yekuenzanisa uyezve kuita geometric kururamisa uye kukanganisa kuongorora. Iwe unogona zvakare kushandisa yakajairwa kugadzirisa bvunzo kadhi, senge bvunzo kadhi ine yakajairwa grid, kutarisa kana mitsetse iri kumapendero yakakombama.
3.Resolution test
Kugadziriswa kwelens kunogadzirisa kujeka kwechifananidzo. Naizvozvo, kugadzirisa ndiyo inonyanya kukosha bvunzo paramende yelens. Inowanzo kuedzwa uchishandisa yakajairwa kugadzirisa bvunzo kadhi ine inoenderana yekuongorora software. Kazhinji, kugadziriswa kwelens kunokanganiswa nezvinhu zvakaita seaperture size uye kureba kwekutarisa.
Kugadziriswa kweLens kunokanganiswa nezvinhu zvakawanda
4.Back focal urefu bvunzo
Back focal kureba chinhambwe kubva pamufananidzo ndege kuenda kumashure kwelenzi. Kune yakamisikidzwa yakatarisa kureba kwelenzi, iyo yekumashure kureba yakagadziriswa, nepo yezoom lens, iyo yekumashure kureba inoshanduka sezvo kureba kwekutarisa kunoshanduka.
5.Sensitivity test
Sensitivity inogona kuongororwa nekuyera iyo yakanyanya kubuda chiratidzo icho lens inogona kuburitsa pasi pemamiriro emwenje chaiwo.
6.Chromatic aberration test
Chromatic aberration inoreva dambudziko rinokonzerwa nekusaenderana kwekutarisa kwemavara akasiyana-siyana echiedza kana lenzi ichiita mufananidzo. Chromatic aberration inogona kuongororwa nekutarisa kana mipendero yeruvara pamufananidzo yakajeka, kana nekushandisa yakakosha bvunzo chati.
7.Kusiyanisa bvunzo
Musiyano ndiwo mutsauko wekupenya pakati pemapoinzi akajeka uye akasviba zvakanyanya mumufananidzo unogadzirwa nelenzi. Inogona kuongororwa nekuenzanisa chigamba chichena kune chitema chitema kana kushandisa yakasarudzika bvunzo chati (yakadai seStupel chart).
Kusiyanisa bvunzo
8.Vignetting test
Vignetting chiitiko chekuti kupenya kwemupendero wemufananidzo kwakadzikira pane kwepakati nekuda kwekuganhurwa kweiyo lens chimiro. Vignetting bvunzo inowanzoyerwa uchishandisa yunifomu chena kumashure kuenzanisa kupenya musiyano pakati pepakati uye kumucheto kwemufananidzo.
9.Anti-Fresnel yekuratidzira bvunzo
Fresnel reflection inoreva chiitiko chekuratidza zvishoma kwechiedza kana ichipararira pakati penhau dzakasiyana. Kazhinji, sosi yemwenje inoshandiswa kuvhenekera lens uye kutarisa ratidziro yekuongorora iyo anti-reflection kugona kwelens.
10.Transmittance test
Transmittance, kureva kuti, kutapurirana kwelenzi kuenda kufluorescence, kunogona kuyerwa uchishandisa michina yakaita se spectrophotometer.
Pfungwa dzekupedzisira:
ChuangAn akaita yekutanga dhizaini uye kugadzirwa kwemichina yekuona lenzi, iyo inoshandiswa mumativi ese emashini ekuona masisitimu. Kana iwe uchifarira kana uine zvinodiwa zvemashini ekuona lenzi, ndapota taura nesu nekukurumidza sezvinobvira.
