Ubwoko byaindorerwamo z'ingandashyiraho

Hari ubwoko bune bw'imiyoboro, ari bwo F-mount, C-mount, CS-mount na M12 mount. F-mount ni ihuriro rikoreshwa muri rusange, kandi muri rusange rikwiriye lens zifite uburebure bwa focal burenga mm 25. Iyo uburebure bwa focal bwa lens y'icyitegererezo buri munsi ya mm 25, bitewe n'uko lens y'icyitegererezo ari nto, C-mount cyangwa CS-mount irakoreshwa, kandi bamwe bakoresha ihuriro rya M12.

Itandukaniro riri hagati ya C mount na CS mount

Itandukaniro riri hagati y’imirongo ya C na CS ni uko intera iri hagati y’aho lens ihurira na kamera igera ku gice cy’inyuma cy’inyuguti (aho sensor ya CCD photoelectric ya kamera igomba kuba iri) itandukanye. Intera iri hagati y’imirongo ya C-mount ni 17.53mm.

Impeta ya adaptateri ya 5mm C/CS ishobora kongerwa kuri lensi ya CS-mount, kugira ngo ibashe gukoreshwa na kamera zo mu bwoko bwa C.

Ibipimo by'ibanze by'indorerwamo z'inganda

Aho ureba (FOV):

FOV yerekeza ku ruhererekane rugaragara rw'ikintu cyabonetse, ni ukuvuga igice cy'ikintu cyafashwe na sensor ya kamera. (Uruhererekane rw'aho ureba ni ikintu kigomba kumvikana mu guhitamo)

Aho ureba

Intera yo gukoreraho (WD):

Bivuga intera iri hagati y'imbere y'ikirahuri n'ikintu kirimo kugeragezwa. Ni ukuvuga intera iri hagati y'ubuso kugira ngo hamenyekane neza.

Umusozo:

Ingano ntoya cyane y'ibintu byasuzumwe ishobora gupimwa hakoreshejwe sisitemu yo gufotora. Akenshi, uko imiterere y'ibintu iba nto, niko imiterere iba myiza kurushaho.

Ubujyakuzimu bw'ishusho (DOF):

Ubushobozi bw'ikirahuri cyo kugumana ubushobozi bwifuzwa mu gihe ibintu biri hafi cyangwa kure y'aho bireba neza.

Izindi parametre zaamatara yo mu nganda

Ingano ya chip ishobora kwangirika n'amafoto:

Ingano y'ubuso bufatika bwa chip ya kamera, muri rusange yerekeza ku bunini butambitse. Iyi parameta ni ingenzi cyane kugira ngo hamenyekane uburyo bukwiye bwo gupima lens kugira ngo haboneke urwego rw'ishusho wifuza. Igipimo cy'ibanze cyo gukura kwa lens (PMAG) gigenwa n'ikigereranyo cy'ingano ya chip ya sensor n'urwego rw'ishusho. Nubwo ibipimo by'ibanze birimo ingano n'urwego rw'ishusho ya chip ya kamera, PMAG si urwego rw'ibanze.

Uburebure bw'inyuma (f):

"Uburebure bw'ifatizo ni igipimo cy'ubwinshi cyangwa itandukaniro ry'urumuri muri sisitemu y'urumuri, bivuze intera iri hagati y'urumuri rw'ikirahure kugeza aho urumuri ruhurira. Ni kandi intera iri hagati y'urumuri ujya ku gice cy'ifoto nka filime cyangwa CCD muri kamera. f={intera ikora/aho ureba uruhande rurerure (cyangwa uruhande rugufi)}XCCD uruhande rurerure (cyangwa uruhande rugufi)

Ingaruka z'uburebure bw'icyerekezo: uko uburebure bw'icyerekezo buto, ni ko uburebure bw'icyerekezo burushaho kuba bwinshi; uko uburebure bw'icyerekezo buto, ni ko uburebure bw'icyerekezo burushaho kuba bwinshi; uko uburebure bw'icyerekezo buto, ni ko ibintu birushaho kuba bibi, bigatuma urumuri rugabanuka ku nkengero z'aho ibintu bihurira.

Umusozo:

Igaragaza intera ntoya iri hagati y'ingingo 2 ishobora kubonwa n'itsinda ry'indorerwamo zireba kure

0.61x y'uburebure bw'umurambararo (λ) / NA = igisubizo (μ)

Uburyo bwo kubara bwavuzwe haruguru bushobora kubara igisubizo mu buryo bwa teyori, ariko ntibukubiyemo kugoreka.

※Uburebure bw'urumuri bukoreshwa ni 550nm

Ibisobanuro:

Umubare w'imirongo y'umukara n'umweru ugaragara hagati ya mm 1. Igice (lp) / mm.

Kugoreka:

Kimwe mu bipimo bipima imikorere y'indorerwamo ni ukudahinduka. Bivuga umurongo ugororotse uri hanze y'umurongo mukuru mu murongo w'ikintu, uba nk'umugozi nyuma yo gufotorwa na sisitemu y'amashusho. Ikosa ryo gufata amashusho y'iyi sisitemu y'amashusho ryitwa kugoreka. Kugoreka bigira ingaruka gusa ku miterere y'ishusho, ntabwo bigira ingaruka ku buhanga bw'ishusho.

Umwobo n'umubare wa F:

Urupapuro rw'amabara y'urumuri ni igikoresho gikoreshwa mu kugenzura ingano y'urumuri runyura muri lens, akenshi ruri imbere muri lens. Dukoresha agaciro ka F kugira ngo tugaragaze ingano y'ahagaragara, nka f1.4, F2.0, F2.8, n'ibindi.

Umwobo n'umubare wa F

Kwagura imbonankubone:

Uburyo bwo kubara igipimo cy'ingenzi cyo gupima ni ubu bukurikira: PMAG = ingano ya sensor (mm) / field of view (mm)

Kwagura ecran

Gukuza ecran bikoreshwa cyane muri mikorosikopi. Gukuza ecran y'ikintu cyapimwe biterwa n'ibintu bitatu: gukura optique kw'ikirahuri, ingano ya sensor chip ya kamera y'inganda (ingano y'ubuso bw'icyerekezo), n'ingano ya ecran.

Kwagura ecran = kwagura lens optique × ingano ya ecran × 25.4 / ingano ya diagonal ya rake

Ibyiciro by'ingenzi by'indorerwamo z'inganda

Gushyira mu byiciro

•Ukurikije uburebure bw'ibanze: prime na zoom

•Ubworoherane: ubworoherane buhamye n'ubworoherane buhindagurika

•Ukoresheje uburyo bwo guhuza: Uburyo bwo guhuza C, uburyo bwo guhuza CS, uburyo bwo guhuza F, nibindi.

•Igabanyijemo ibipimo byinshi: lensi yo kongera ubushobozi idahinduka, lensi yo gukurura ihoraho

•Lense z'ingenzi cyane zikoreshwa mu nganda zikora imashini zireba cyane cyane zirimo lense za FA, lense za telecentric na mikorosikopi z'inganda, n'ibindi.

Ingingo z'ingenzi zigomba kwitabwaho mu guhitamoindorerwamo y'imashini ireba:

1. Aho ureba, kongera urumuri n'intera wifuza gukora: Mu gihe uhitamo lenzi, tuzahitamo lenzi ifite aho ureba hanini gato ugereranyije n'ikintu kigomba gupimwa, kugira ngo tworohereze kugenzura uko ibintu bigenda.

2. Ibisabwa mu bujyakuzimu bw'aho ukorera: Ku mishinga isaba ubujyakuzimu bw'aho ukorera, koresha umwanya muto uko bishoboka kose; mu gihe uhitamo lenzi ifite ubushobozi bwo kongera uburebure, hitamo lenzi ifite ubushobozi bwo kongera uburebure buri hasi uko umushinga ubishoboye. Niba ibisabwa mu mushinga ari byinshi, nkunda guhitamo lenzi igezweho ifite ubushobozi bwo kongera uburebure buri hejuru.

3. Ingano y'ibipimo n'uburyo kamera ikoreshwa: Urugero, lenzi ya 2/3″ ishyigikira ubuso bunini bwa kamera ikora mu nganda ni 2/3″, ntishobora gushyigikira kamera ikora mu nganda nini kurusha santimetero 1.

4. Umwanya uhari: Ntibishoboka ko abakiriya bahindura ingano y'ibikoresho mu gihe gahunda ari ngombwa.
