Makamera maindasitiri ndiwo akakosha zvikamu muzvikwata zvemabhuku. Basa ravo rinokosha kwazvo nderekushandura zviratidzo zveonde kuita zviratidzo zvemagetsi zvemagetsi zvemaindasitiri akakwira-tsanangudzo yeindasitiri.
MuChinese kuona masisitimu, lens yeindasitiri kamera yakaenzana neziso remunhu, uye basa rayo guru ndeyekuisa chinangwa chechiratidzo chechifananidzo pane photosensitive nzvimbo yemifananidzo (maindasitiri kamera).
Yese yemifananidzo yemifananidzo yakagadziriswa neiyo inoonekwa system inogona kuwanikwa kubva kune lens yekamera yeindasitiri. Kunaka kweMaindasitiri kamera lensichakanganisa zvakananga kuita kwakazara kwegadziriro yekuona.
Semhando yekufungidzira michina, kamera yeindasitiri kazhinji inowanzo fomu yemifananidzo izere yekuwana ine simba, neizvozvo, kusarudzwa kwemaindasitiri ekare Kazhinji, inogona kuongororwa uye inotariswa kubva pane zvinotevera zvinhu:
1.Wavelength uye zoom lens kana kwete
Zviri nyore kusimbisa kana kamera yeindasitiri inoda kuti zooms inonakidza kana yakagadziriswa-inotarisa lens. Kutanga, zvinodikanwa kuti uone kana iyo inoshanda wavelength yemuindasitiri kamera lens iri kutarisisa. Munguva yekufungidzira, kana kukura kuchikosha kuti kushandurwa, zoom lens inofanira kushandiswa, neimwe nzira nzira yakatarwa-inotarisa yakaringana.
Maererano neinoshanda wavelength yeMaindasitiri kamera lenses, bhendi rinoonekera rinoonekwa rinonyanya kuzivikanwa, uye kune zvakare zvinoshandiswa mune mamwe mabhendi. Zvimwe zvinowedzerwa zviyero zvinodiwa? Iro monochromatic kana polychromatic mwenje? Ko simba remwenje rakatsauka rinogona kudziviswa zvinobudirira here? Izvo zvinodikanwa kuti usanzwisise zvakaremedza zvinhu zviri pamusoro usati wabvisa iyo inoshanda wavelength ye lens.

2.Kunyanya kukosheswa kunopihwa kune zvakakosha zvikumbiro
Zvichienderana nekunyorera chaiko, panogona kunge paine zvinokosha zvinodiwa. Zvinodiwa Zvinodiwa Pakutanga, semuenzaniso, kungave kune chiyero chekuyera, kana iyo imagesmi yekudzika, etcc. Yakadzika yekutarisa kazhinji haina kutorwa zvakanyanya, asi chero mufananidzo wekugadzirisa maitiro anofanira gadzirisa.
3.Kushanda kureba uye kufuka urefu
Kushanda kureba uye kufuka kureba kunowanzoonekwa pamwe chete. Pfungwa yakajairika ndeyekutanga kuona iyo System resolution, wobva wanzwisisa kukura kweiyo CCD pixel size, uye nekureba kwekusanganiswa kweiyo spatial chimiro chemagetsi, kuti uwedzere kufungidzira urefu hwe Maindasitiri kamera lens.
Naizvozvo, urefu hwekushamwaridzana hwemaindasitiri kamera ine hukama hwekushanda kwedare reindasitiri kamera lens uye kamera resolution (pamwe neCCD pixel size).
Zvinhu zvekufunga kana uchisarudza maindasitiri kamera lenses
4.Saizi yemifananidzo uye mufananidzo wemufananidzo
Saizi yemifananidzo yeMaindasitiri kamera lenskusarudzwa inofanira kuwirirana neiyo photosensitive saizi yeindasitiri kamera, uye hombe yekugara zvidiki "inofanira kuteverwa Mhando yemufananidzo yemugumo yemunda wekutarisa haigoni kuvimbiswa.
Izvo zvinodiwa nekufungidzira mhando zvinonyanya kuvimba neMTF uye kukanganisa. Muchiyero chekushandisa, kukanganisa kunofanirwa kupihwa zvakanyanya.
5.Aperture uye lens gomo
Kuparadzwa kweshandare yeindasitiri inonyanya kukanganisa kupenya kwekufungidzira, asi muzviratidzo zvazvino, kamera, kamera, sosi yekubatanidza, etc. saka, kuitira kuti Tora iyo inodiwa mufananidzo kupenya, matanho mazhinji ekugadzirisa anodikanwa.
Iyo Lens Gomo rekamera yeindasitiri inoreva iyo inokwira interface pakati peiyo lens uye kamera, uye maviri aya anofanira kuenderana. Kana vaviri vacho vasingaenderane, kutsiva kunofanirwa kutariswa.
Zvinhu zvekufunga kana uchisarudza maindasitiri kamera lens
6.Mutengo uye tekinoroji kukura
Kana mushure mekuratidzwa kwakakwana kwezvikamu zviri pamusoro apa, pane mhinduro dzakawanda dzinosangana nezvinodiwa, unogona kufunga nezvekukura kwakazara uye hunyanzvi hwekukura, uye uvakwanise kwavari.
PS: Muenzaniso weLens Sarudzo
Pazasi isu tinopa muenzaniso wekusarudza lens kune kamera yeindasitiri. Semuenzaniso, muchina wewireni siginecha yekuona mari inoda kuti ive yakagadzirirwa neMaindasitiri kamera lens. Iwo anozivikanwa mishonga: Iyo indasitiri kamera CCD ndeye 2/3 inches sosi yechiedza.
Kuongororwa kwekutanga kwekusarudza lenses ndeye zvinotevera:
(1.
.
(3) Kushanda kureba uye kufuka urefu:
Mufananidzo Magnifation: M = 4.65 / (0.05 x 1000) = 0.093
Foral urefu: F = l * m / (m + 1) = 200 * 0.093 / 1.093 = 17mm
Kana chinhambwe chinhambwe chinodiwa kuti uve mukuru kuna 200mm, urefu hwemahara hwemazini akasarudzwa hunofanirwa kunge hukuru kupfuura 17mm.
.
. Iko hakuna chinodiwa chekuparadza panguva yacho.
Kuburikidza nekuongororwa uye kuverenga kwezvinhu zviri pamusoro apa, isu tinogona kuwana yekutanga "yeredhiyo yeindasitiri kamera, yakajeka kutaridzika, C-gomo, inoenderana ne 2/3-inch ccd size ye pixel, uye chidiki chidiki chinokanganisa. Zvichienderana nezvinodiwa izvi, kumwe kusarudzwa kunogona kuitwa. Kana ma lenses akati wandei anogona kuzadzisa izvi zvinodiwa, zvinokurudzirwa kuenderera mberi uye kusarudza iyo yakanakisa lens.
Pfungwa dzekupedzisira:
Chulangan yakaita dhizaini yekutanga uye kugadzirwa kweMaindasitiri Lenses, iyo inoshandiswa mune zvese zvikamu zvemaindasitiri ekushandisa. Kana iwe uchifarira kana uine zvinodiwa kune maindasitiri maindasitiri, ndapota taura nesu nekukurumidza sezvinobvira.
