Ungawahlola kanjani ama-lens wombono womshini? Iziphi izindlela?

Ukuze uqinisekise ukuthi i-lens inganikeza izithombe ezisezingeni eliphakeme nokusebenza okuthembekile kwizimo ezithile zohlelo lokusebenza, kuyadingeka ukwenza ukuhlola okufanele kumalensi. Ngakho-ke, yiziphi izindlela zokuhlola zeAmalensi wombono woMshini? Kulesi sihloko, sizofunda ukuthi singakuhlola kanjani ama-Menses wens wens.

Yiziphi izindlela zokuhlola amalensi wombono womshini?

Ukuhlolwa kwamalensi wokubuka umshini kudinga ukucubungula izici eziningi zamapharamitha okusebenza nezimpawu, futhi kudinga ukwenziwa ngaphansi kokusebenza kwemishini ekhethekile kanye nabaqeqeshiwe ukuqinisekisa ukuthi imiphumela yokuhlola ilungile futhi iyasebenza.

Okulandelayo izindlela zokuhlola eziphambili:

1.Inkambu yokuhlola ukuhlolwa

Inkambu yokubukwa kwelensi inquma usayizi wesigameko esibona uhlelo lwe-optical, futhi imvamisa ingahlolwa ngokukala ububanzi besithombe esakhiwe yilensi ebulungiswa yilensi.

2.Ukuhlolwa kokuhlanekezela

Ukuhlanekezela kubhekiswa ekuguqukeni okwenzeka lapho amaphrojekthi we-lens anento yangempela endizeni ecabangayo. Kunezinhlobo ezimbili eziphambili: ukuhlanekezela kwe-barrel kanye nokuhlanekezela kwe-pencesion.

Ukuhlola kungenziwa ngokuthatha izithombe zokulinganisa bese wenza ukulungiswa kwejometri nokuhlaziywa kokuhlanekezela. Ungasebenzisa futhi ikhadi lokuhlola lesinqumo elijwayelekile, njengekhadi lokuhlola elinegridi ejwayelekile, ukubheka ukuthi imigqa emaphethelweni igobile yini.

3.Ukuhlolwa kwesinqumo

Ukulungiswa kwelensi kunquma ukucaciswa kwemininingwane yesithombe. Ngakho-ke, ukulungiswa kuyindlela ebaluleke kakhulu yokuhlola yelensi. Imvamisa ihlolwe kusetshenziswa ikhadi lokuhlola lesinqumo esijwayelekile ngesoftware yokuhlaziya ehambisanayo. Imvamisa, ukulungiswa kwamalensi kuthinteka yizinto ezifana nosayizi we-aperture nobude obugxile.

4.BUkuhlolwa kobude obugxile kwe-ACK

Ubude obugxile emuva ibanga ukusuka endizeni yesithombe kuya emuva kwelensi. Ngelensi yobude obugxile egxilile, ubude obugxile emuva buhleliwe, ngenkathi i-lens zoom, ubude obugxile emuva buguquka njengoba ubude bangempela buguquka njengoba ubude bangempela buguquka.

5.Ukuhlolwa kokuzwela

Ukuzwela kungahlaziywa ngokukala isinali yokuphuma ephezulu yokuthi ilensi ingakhiqiza ngaphansi kwezimo ezithile zokukhanyisa.

6.Ukuhlolwa kwe-chromatic abrrration

I-Chromatic Abrrrration isho inkinga ebangelwa ukungahambisani kwamaphoyinti agxile kwemibala ehlukahlukene yokukhanya lapho amalensi enza isithombe. Ukushintshwa kwe-chromatic kungahlaziywa ngokubheka ukuthi ngabe imigqa yombala esithombeni icacile, noma ngokusebenzisa ishadi elikhethekile lokuhlola umbala.

7.Ukuhlolwa kokuqhathanisa

Ukuqhathanisa kungumehluko ekukhazimuleni phakathi kwamaphoyinti aqhakazile futhi amnyama kakhulu esithombeni esikhiqizwe yilensi. Ingahlolwa ngokuqhathanisa isichibi esimhlophe ku-patch emnyama noma ngokusebenzisa ishadi lokuhlola elikhethekile lokuhlola (njengeshadi le-stupel).

8.Ukuhlolwa kweVignetting

IVignigning yisimo sokukhanya kwesikhafu sesithombe esiphansi kunaleso sikhungo ngenxa yomkhawulo wesakhiwo selensi. Ukuhlolwa kweVigningting kuvame ukukalwa kusetshenziswa isizinda esimhlophe esifanayo ukuqhathanisa umehluko wokukhanya phakathi kwesikhungo namandla wesithombe.

9.Ukuhlolwa kokubonisa okulwa ne-freen

I-Fresnel Reflection isho into ebonakalayo yokuboniswa okuyingxenye kokukhanya lapho isakaza phakathi kwemidiya ehlukene. Imvamisa, kuvame ukuba ngumthombo wokukhanya ukukhanyisela ilensi futhi uqaphele ukuboniswa ukuhlola amandla okubhala amalensi.

10.Ukuhlolwa kweTransmittance

Ukudluliselwa, okungukuthi, ukudluliselwa kwelensi ku-fluorescence, kungalinganiswa kusetshenziswa imishini efana ne-spectrophotometer.

Imicabango yokugcina:

UChuangan wenze ukwakheka kokuqala nokukhiqizwa kweAmalensi wombono woMshini, ezisetshenziswa kuzo zonke izici zezinhlelo zombono womshini. Uma unentshisekelo noma unezidingo zamalensi wombono womshini, sicela uxhumane nathi ngokushesha okukhulu.
