Kona yechiedza che lens ndiyo kona iri pakati pe optical axis ne lens chief ray. Iyo lens chief ray ndiyo ray inopfuura nepa aperture stop ye optical system nemutsetse uri pakati pe entrance pupil's center nenzvimbo ye object. Chikonzero chekuvapo kweCRA mu Image Sensor ndechekuti pane FOV (Field of view) paMirco Lens pamusoro pe Image Sensor, uye kukosha kweCRA kunoenderana ne horizontal error value pakati pe Micro Lens ye Image Sensor nenzvimbo ye silicon photodiode. Chinangwa ndechekuenzanisa zviri nani lens.
Kona yemwaranzi huru yelenzi
Kusarudza CRA inoenderana neLens&Image Sensor kunogona kuve nechokwadi chekuti ma photon anotorwa nemazvo mu silicon photodiodes, zvichiita kuti pasave nekusawirirana pakati pe optical crosstalk.
Kune ma sensor emifananidzo ane ma pixel madiki, kona huru yemwaranzi yave chinhu chakakosha. Izvi zvinodaro nekuti chiedza chinofanira kupfuura nepakati pe pixel kuti chisvike pa silicon photodiode iri pasi pe pixel, izvo zvinobatsira kuwedzera huwandu hwechiedza chinopinda mu photodiode uye kuderedza huwandu hwechiedza chinopinda mu silicon photodiode ye pixel iri pedyo (Kugadzira optical crosstalk).
Saka, kana Image sensor ikasarudza lenzi, inogona kukumbira mugadziri weImage Sensor nemugadziri welenzi kuti vagadzire CRA curve kuti ienderane; zvinowanzokurudzirwa kuti musiyano wekona yeCRA pakati peImage Sensor nelenzi utongwe mukati me +/-3 degrees, hongu, kana Pixel idiki, ndipo panodiwa zvakawanda.
Mhedzisiro yekusawirirana kwelenzi yeCRA nesensor yeCRA:
Kusawirirana kunoguma nekutaura kwakasiyana-siyana zvichikonzera kusawirirana kwemavara pamufananidzo, zvichikonzera kudzikira kwechiratidzo-ku-ruzha (SNR); sezvo CCM ichida kuwedzera kwekuwedzera kwedhijitari kuti itsive kurasikirwa kwechiratidzo muphotodiode.
Mhedzisiro yekusawirirana kwelens CRA ne sensor CRA
Kana CRA isingaenderane, ichakonzera matambudziko akadai semifananidzo isina kujeka, mhute, kusiyana kushoma, mavara asina kujeka, uye kudzika kwenzvimbo.
Lenzi yeCRA idiki pane iyo Image Sensor CRA inogadzira ruvara.
Kana Image Sensor iri diki pane lens CRA, lens ichaonekwa ine shading.
Saka tinofanira kutanga taona kuti ruvara rwemavara haruonekwe, nekuti ruvara rwemalenzi rwuri nyore kugadzirisa kuburikidza nekubvisa matambudziko pane ruvara rwemavara.
Sensor yemufananidzo uye lenzi yeCRA
Zvinogona kuonekwa kubva pamufananidzo uri pamusoro apa kuti TTL yelenzi ndiyo kiyi yekuona angle yeCRA. Kana TTL yakaderera, angle yeCRA yakakura. Saka, sensor yemufananidzo ine mapikiseti madiki yakakoshawo pakufananidza lenzi yeCRA pakugadzira sisitimu yekamera.
Kazhinji, lenzi yeCRA hainyatsoenderana neImage sensor CRA nekuda kwezvikonzero zvakasiyana-siyana. Zvakaonekwa mukuyedza kuti lenzi yeCRA ine mativi akatsetseka (akapfava) inoshivirira kusiyana kwemamodule emakamera kupfuura maCRA akakombama.
Lenzi yeCRA hainyatsoenderana neImage sensor CRA nekuda kwezvikonzero zvakasiyana-siyana
Mifananidzo iri pazasi inoratidza mienzaniso yematanda akatsetseka uye maCRA akakombama.
Mienzaniso yeCRA dzakatsetseka uye dzakakombama
Kana CRA yelenzi yakasiyana zvakanyanya neCRA yesensa yemufananidzo, ruvara rwacho ruchaonekwa sezvakaratidzwa mumufananidzo uri pazasi.
