Ungawahlola Kanjani Amalensi Ombono Womshini? Yiziphi Izindlela?

Ukuze uqinisekise ukuthi ilensi inganikeza izithombe zekhwalithi ephezulu nokusebenza okuthembekile kuzimo ezithile zohlelo lokusebenza, kuyadingeka ukwenza ukuhlola okufanelekile kulensi. Ngakho-ke, yiziphi izindlela zokuhlolaumshini wokubona lens? Kulesi sihloko, sizofunda indlela yokuhlola amalensi ombono womshini.

Ungawahlola kanjani amalensi okubona omshini

Yiziphi izindlela zokuhlola zamalensi okubona omshini?

Ukuhlolwa kwamalensi ombono womshini kudinga ukucabangela izici eziningi zemingcele nezici zokusebenza, futhi kudinga ukwenziwa ngaphansi kokusebenza kwemishini ekhethekile nochwepheshe ukuze kuqinisekiswe ukuthi imiphumela yokuhlola ilungile futhi iyasebenza.

Okulandelayo izindlela zokuhlola eziyinhloko:

1.Ukuhlolwa kwendawo yokubuka

Inkambu yokubuka ilensi inquma usayizi wesigcawu esingabonwa isistimu yokubona, futhi ngokuvamile ingahlolwa ngokulinganisa ububanzi besithombe esakhiwe ilensi ngobude obuthile bokugxila.

2.Ukuhlolwa kokuhlanekezela

Ukuhlanekezela kubhekisela ekuwohlokeni okwenzeka lapho ilensi ikhiqiza into yangempela endizeni yesithombe. Kunezinhlobo ezimbili eziyinhloko: ukuhlanekezela komgqomo kanye nokuhlanekezela kwe-pincushion.

Ukuhlola kungenziwa ngokuthatha izithombe zokulinganisa bese kwenziwa ukulungisa kwejiyomethri nokuhlaziya ukuhlanekezela. Ungasebenzisa futhi ikhadi lokuhlola ukulungiswa okujwayelekile, njengekhadi lokuhlola elinegridi evamile, ukuze uhlole ukuthi imigqa emaphethelweni igobile yini.

3.Ukuhlolwa kwesinqumo

Ukulungiswa kwelensi kunquma imininingwane ecacile yesithombe. Ngakho-ke, ukulungiswa kuyipharamitha yokuhlola ebaluleke kakhulu yelensi. Ivamise ukuhlolwa kusetshenziswa ikhadi elijwayelekile lokuhlola ukulungiswa elinesofthiwe ehambisanayo yokuhlaziya. Ngokuvamile, ukulungiswa kwelensi kuthintwa izici ezifana nosayizi wokuvula kanye nobude bokugxila.

4.Bukuhlolwa kobude be-ack obugxile

Ubude bokugxila emuva yibanga ukusuka endizeni yesithombe ukuya ngemuva kwelensi. Ukuze uthole ilensi yobude obugxilile obugxilile, ubude bokugxila emuva bugxilile, kuyilapho ilensi yokusondeza, ubude obugxile emuva bushintsha njengoba ubude bokugxila bushintsha.

5.Ukuhlolwa kokuzwela

Ukuzwela kungahlolwa ngokulinganisa isignali ephezulu yokuphuma engakhiqizwa ilensi ngaphansi kwezimo ezithile zokukhanya.

6.Ukuhlolwa kwe-Chromatic aberration

I-Chromatic aberration ibhekisela enkingeni ebangelwa ukungahambisani kwamaphoyinti okugxiliswa kuwo emibala ehlukahlukene yokukhanya lapho ilensi yakha isithombe. I-Chromatic aberration ingahlolwa ngokubheka ukuthi amaphethelo ombala esithombeni acacile yini, noma ngokusebenzisa ishadi lokuhlola lombala elikhethekile.

7.Ukuhlolwa kokuqhathanisa

Umehluko umehluko wokukhanya phakathi kwamaphoyinti agqamile namnyama kakhulu esithombeni esikhiqizwe ilensi. Ingahlolwa ngokuqhathanisa ipheshi elimhlophe nesiqeshana esimnyama noma ngokusebenzisa ishadi elikhethekile lokuhlola ukugqama (njengeshadi le-Stupel).

8.Ukuhlolwa kwe-Vignetting

I-Vignetting isenzakalo sokuthi ukukhanya konqenqema lwesithombe kungaphansi kwalokho kwesikhungo ngenxa yomkhawulo wesakhiwo selensi. Ukuhlolwa kwe-Vignetting kuvame ukukalwa kusetshenziswa ingemuva elimhlophe elifanayo ukuze kuqhathaniswe umehluko wokukhanya phakathi kwesikhungo nomkhawulo wesithombe.

9.Ukuhlolwa kwe-Anti-Fresnel reflection

I-Fresnel reflection ibhekisela kwinto yokubonakala kwengxenye yokukhanya lapho isakazeka phakathi kwemidiya ehlukene. Ngokuvamile, umthombo wokukhanya usetshenziselwa ukukhanyisa ilensi futhi ubuke ukubonakaliswa ukuze kuhlolwe ikhono lelensi elimelene nokubonakala.

10.Ukuhlolwa kokudlulisela

Ukudluliswa, okungukuthi, ukudluliswa kwelensi ku-fluorescence, kungalinganiswa kusetshenziswa okokusebenza njenge-spectrophotometer.

Imicabango yokugcina:

UChuangAn wenze umklamo wokuqala kanye nokukhiqizwa kweumshini wokubona lens, ezisetshenziswa kuzo zonke izici zomshini wokubona izinhlelo. Uma unentshisekelo noma unezidingo zamalensi ombono womshini, sicela usithinte ngokushesha okukhulu.
