Nigute Twasuzuma Imashini Iyerekwa? Ni ubuhe buryo?

Kugirango tumenye neza ko lens ishobora gutanga amashusho yujuje ubuziranenge hamwe n’imikorere yizewe mu bihe byihariye byo gusaba, ni ngombwa gukora isuzuma rijyanye na lens. None, ni ubuhe buryo bwo gusuzumaimashini yerekana imashini? Muri iki kiganiro, tuziga uburyo bwo gusuzuma imashini zerekana imashini.

Nigute ushobora gusuzuma imashini yerekana imashini

Nubuhe buryo bwo gusuzuma bwakorewe imashini?

Isuzumabumenyi ryerekana imashini zigomba gusuzuma ibintu byinshi byerekana ibipimo ngenderwaho n'ibiranga, kandi bigomba gukorwa hifashishijwe ibikoresho kabuhariwe hamwe nababigize umwuga kugirango ibisubizo by'isuzuma bibe byiza kandi byiza.

Ibikurikira nuburyo bukuru bwo gusuzuma:

1.Umwanya wo kureba ikizamini

Umwanya wo kureba lens igena ubunini bwibintu sisitemu optique ishobora kubona, kandi mubisanzwe birashobora gusuzumwa mugupima diameter yishusho yakozwe na lens muburebure bwihariye.

2.Ikizamini cyo kugoreka

Kugoreka bivuga guhindura ibintu bibaho mugihe lens yerekana ikintu gifatika kumurongo wamashusho. Hariho ubwoko bubiri bwingenzi: kugoreka ingunguru no kugoreka pincushion.

Isuzuma rishobora gukorwa no gufata amashusho ya kalibrasi hanyuma ugakora ubugororangingo bwa geometrike no gusesengura ibintu. Urashobora kandi gukoresha ikarita yikizamini gisanzwe, nkikarita yikizamini hamwe na gride isanzwe, kugirango urebe niba imirongo kumpande yagoramye.

3.Ikizamini cyo gukemura

Ikemurwa rya lens rigena ibisobanuro birambuye kumashusho. Kubwibyo, gukemura nikintu gikomeye cyibizamini bya lens. Mubisanzwe bipimishwa ukoresheje ikarita yikizamini gisanzwe hamwe na software ikora isesengura. Mubisanzwe, imikemurire yinzira igira ingaruka kubintu nkubunini bwa aperture nuburebure bwibanze.

Gukemura lens bigira ingaruka kubintu byinshi

4.Back yibanze uburebure

Uburebure bwibanze inyuma ni intera kuva ishusho yindege kugeza inyuma yinzira. Kuburebure bwerekanwe bwerekanwe, uburebure bwinyuma bwibanze burashizweho, mugihe kuri zoom zoom, uburebure bwinyuma bwibanze burahinduka nkuko uburebure bwibanze buhinduka.

5.Ikizamini cyo kumva

Ibyiyumvo birashobora gusuzumwa mugupima ibimenyetso ntarengwa byerekana ko lens ishobora kubyara mugihe cyihariye cyo kumurika.

6.Ikizamini cya Chromatic aberration

Chromatic aberration bivuga ikibazo cyatewe no kudahuza ingingo yibanda kumabara atandukanye yumucyo mugihe lens ikora ishusho. Chromatic aberration irashobora gusuzumwa harebwa niba impande zamabara kumashusho zisobanutse, cyangwa ukoresheje imbonerahamwe idasanzwe yo gupima ibara.

7.Ikigereranyo gitandukanye

Itandukaniro ni itandukaniro ryumucyo hagati yumucyo kandi wijimye mwishusho yakozwe na lens. Irashobora gusuzumwa ugereranije igipande cyera nigishishwa cyumukara cyangwa ukoresheje imbonerahamwe idasanzwe yikigereranyo (nkimbonerahamwe ya Stupel).

Ikigereranyo gitandukanye

8.Ikizamini cya Vignetting

Vignetting nikintu cyerekana ko umucyo wuruhande rwishusho uri munsi yuw'ikigo bitewe no kugabanya imiterere ya lens. Ikizamini cya Vignetting mubusanzwe gipimwa hifashishijwe ibara ryera ryera kugirango ugereranye itandukaniro ryumucyo hagati hagati nuruhande rwishusho.

9.Ikizamini cyo kurwanya anti-Fresnel

Kugaragaza kwa Fresnel bivuga ibintu byo kwerekana igice igice cyumucyo iyo gikwirakwije mubitangazamakuru bitandukanye. Mubisanzwe, isoko yumucyo ikoreshwa mukumurikira lens no kwitegereza kugirango isuzume ubushobozi bwo kurwanya-lens.

10.Ikizamini cyo kohereza

Kwimura, ni ukuvuga kohereza lens kuri fluorescence, birashobora gupimwa ukoresheje ibikoresho nka spekitifotometero.

Ibitekerezo bya nyuma ：

ChuangAn yakoze igishushanyo mbonera n'umusaruro waimashini yerekana imashini, zikoreshwa mubice byose bya sisitemu yo kureba imashini. Niba ushimishijwe cyangwa ukeneye ibyuma byerekana imashini, nyamuneka twandikire vuba bishoboka.
