Ingaruka zindi lens zibisobanuro bimwe ariko ibishushanyo bitandukanye ku ishusho
Ingaruka zamashusho yubushyuhe hamwe nibisobanuro bimwe ariko ibishushanyo bitandukanye kubishushanyo bigaragazwa cyane mubitandukaniro mubisobanuro bya optique. Nubwo ibisobanuro (nko kwibandaho, aperture, imiterere yo kureba, gukemura, nibindi) birashobora gutuma ibintu bikunze kugaragara muburyo bufatika:
1. Ubushobozi bwo gukosora bwa Aberration
Itandukaniro mumiterere ya Optique: umubare, imiterere, nuburyo bwo gukoresha inzira Lens hamwe nibishushanyo byinshi bigoye guhagarika inkombe na chromatic asberration, bityo bigatera imbere guhuza hagati yikigo nukuge.
Ubushyuhe bwumuriro: Lens yigisha amashusho akoreshwa ahanini mubushyuhe bunini. Itandukaniro muri Coefficion yo Kwagura Ubushyuhe bwibikoresho bitandukanye (nkikigereki, ikirahuri cyigitsina, na chalcogenide) bishobora gutera ubuziranenge bwa Drift mugihe imyumvire yubushyuhe. Lens hamwe nigikorwa cyoroshye kizagabanya uburyo bwumurakunde bwumuriro binyuze mumitungo ihuye cyangwa imashini.
2. GUHINDUKA KANDI GUHUZA
Anti - Gutwika Gutwika: Inzira zitandukanye zo gutora zigira ingaruka kumurika no guhindagurika no guhindagurika kumucyo mumatsinda ya infrared (nka 8 - 14μm). Hejuru - Amavuta meza arashobora kunoza ibimenyetso - - igipimo cyurusaku, kugabanya "amashusho yumuzimu" no gukora amashusho asobanutse neza, cyane cyane hafi yubushyuhe bwinshi (nka flames - Ibikoresho byubushyuhe).
Ibiranga ibikoresho biranga: Nubwo ibisobanuro bimwe, itandukaniro muburyo bwo kwera cyangwa gukora ingengabihe yibikoresho bya lens bishobora gutera kwamagana uburebure bumwe bwo kugabanuka, bigira ingaruka ku mashusho.
3. Kumenyekana no kugenzura urusaku
Aperture no kuvura urukuta rwimbere: Umwanya nuburyo bya Aperture hamwe nuburyo bwo gufata urukuta rwimbere rwa lens barrel (nkimiterere yumukara hamwe ninzira yumukara) bizagira ingaruka kumuntu wo gucana. Lened yagenewe nabi irashobora gutera Halo cyangwa ibihangano bikikije hejuru - intego zubushyuhe, kugabanya imyanzuro irambuye.
Ingaruka ya Narcissus: Mubishushanyo bimwe na bimwe, umupaka wubushyuhe ugaragara gusubira kuri detector ukoresheje lens, zikora ibibara byijimye. Ibishushanyo byiza bigabanya ibihangano nkibi binyuze muri lens curvature cyangwa guhiga.
4. Imiterere ya mashini no kuramba
Kwibanda na zoom uburyo bwo kwibandaho: UBUYOBOZI BW'INGINGO / AUTO yibanda ku kashe (umukungugu no kurwanya amazi) bigira ingaruka ku gihagararo cya buri gihe - Ikoreshwa ry'amazi. Kurugero, kashe mibi irashobora gutera lens igihuru, kugabanya ubuziranenge bwishusho muburyo buhebuje.
Anti - Kunyeganyeza: Mubikorwa Porogaramu, uburyo itsinda rya Lens rihabwa ingaruka ku kurwanya (kunyeganyega. Igihe kirekire - Ijambo kunyeganyega rishobora gutera umurongo wa optique kugirango uhindure kandi rigire ingaruka ku bukari.
5. Umwanzuro nyawo na MTF umurongo
Nominal vs yapimwe kubisobanuro: Muburyo bumwe "Hafi", itandukaniro ryo kwimura imikorere (MTF) rishobora kuganisha ku gishushanyo gitandukanye. Kurugero, lens hamwe na mtf yihuta ku nkombe yumurima wibireba bizahindura ibisobanuro birambuye iyo bisa ku ngufu nini.
Guhuza Guhuza: Niba igishushanyo mbonera gishushanyije kuri statector yihariye (nko mubunini bwa pigiseli, ecran yubukonje) bizagira ingaruka kubikorwa nyabyo. Ibishushanyo bidasubirwaho birashobora gutera guhakana cyangwa kwinjiza.
6. Guhuza n'imihindagurikire yo gusaba
Funga - Urwego Gutekereza: Ibishushanyo bimwe byateguwe hafi - nko kwibanda kunganda), mugihe abandi bashobora kwibasirwa na kurera ubuziranenge kugirango bafunge cyangwa ba kure mubisobanuro bimwe .
Gutunganya amanota meza: Kuri Hejuru - Amashusho meza (nko kuboneka cyane cyane cyane hamwe nigihe kimwe), guhanagura ubushyuhe bukabije), Guhuza Igenzura ryibintu bimwe), Guhuza Ibisubizo byatanzwe cyangwa Guhuza Ibisubizo Byinshi birashobora kugira uruhare muri lens zitandukanye bishobora kugira ingaruka kubushobozi bwo kugarura ibice.
Ibyifuzo byo guhitamo
Reba kuri MTF umurongo kandi upimye amakuru: Ibisobanuro ntibishobora kwerekana neza imikorere nyayo kandi bigomba guhuzwa nibizamini bya laboratoire (nko kugerageza guhuza laboratoire (nko kugerageza guhuza amabuye, urusaku ruhwanye nubushyuhe bwa Netd).
Imiterere y'ibidukikije: Hitamo igishushanyo mbonera cyiza cyo gutora no gushyirwaho ikimenyetso ukurikije imiterere yimikoreshereze (ubushyuhe bwinshi, ubushyuhe bwinshi, kunyeganyega).
Kugenzura Igenzura: Menya neza ko ingano ya pigiseli na ecran ya ground F Umubare wimyenda ihuye nuwatezimbere kugirango wirinde imyanda cyangwa vignetting.
Muri make, ibisobanuro birambuye bya lenter yamashusho yubushyuhe bizagira ingaruka zikomeye ku ishusho yanyuma, cyane cyane mubidukikije - Gusaba Gusaba guhuzwa nibikorwa byapimwe aho kwishingikiriza.
