Ukuze kuqinisekiswe ukuthi ilensi inganikeza izithombe ezisezingeni eliphezulu kanye nokusebenza okuthembekile ezimweni ezithile zohlelo lokusebenza, kubalulekile ukwenza ukuhlolwa okufanele kulensi. Ngakho-ke, yiziphi izindlela zokuhlola zeamalensi okubona komshiniKulesi sihloko, sizofunda ukuthi singazihlola kanjani amalensi okubona komshini.
Indlela yokuhlola amalensi ombono womshini
Yiziphi izindlela zokuhlola amalensi ombono womshini?
Ukuhlolwa kwamalensi okubona komshini kudinga ukucabangela izici eziningi zemingcele yokusebenza kanye nezici, futhi kudinga ukwenziwa ngaphansi kokusebenza kwemishini ekhethekile kanye nochwepheshe ukuqinisekisa ukuthi imiphumela yokuhlola ilungile futhi iyasebenza.
Nazi izindlela eziyinhloko zokuhlola:
1.Ukuhlolwa kwensimu yokubuka
Insimu yokubuka ilensi inquma ubukhulu besigcawu esingabonwa uhlelo lwe-optical, futhi ngokuvamile ingahlolwa ngokulinganisa ububanzi besithombe esakhiwe ilensi ngobude obuqondile.
2.Ukuhlolwa kokuhlanekezela
Ukuhlanekezela kubhekisela ekuguquguqukeni okwenzeka lapho ilensi ikhipha into yangempela endizeni yesithombe. Kunezinhlobo ezimbili eziyinhloko: ukuhlanekezela kwebhareli kanye nokuhlanekezela kwe-pincushion.
Ukuhlola kungenziwa ngokuthatha izithombe zokulinganisa bese wenza ukulungiswa kwejometri kanye nokuhlaziywa kokuhlanekezela. Ungasebenzisa futhi ikhadi lokuhlola elijwayelekile, njengekhadi lokuhlola elinegridi ejwayelekile, ukuhlola ukuthi imigqa emaphethelweni igobile yini.
3.Ukuhlolwa kwesisombululo
Isixazululo selensi sinquma ukucaca kwemininingwane yesithombe. Ngakho-ke, isixazululo siyipharamitha yokuhlola ebaluleke kakhulu yelensi. Ngokuvamile sihlolwa kusetshenziswa ikhadi lokuhlola isixazululo elijwayelekile elinesofthiwe yokuhlaziya ehambisanayo. Ngokuvamile, isixazululo selensi sithinteka yizici ezifana nosayizi wokuvula kanye nobude obuqondile.
Ukulungiswa kwelensi kuthinteka yizici eziningi
4.Bukuhlolwa kobude be-ack focal
Ubude bokugxila emuva buyibanga elisuka endaweni yesithombe liye ngemuva kwelensi. Kulensi enobude obuqondile, ubude bokugxila emuva buzinzile, kanti ngelensi yokusondeza, ubude bokugxila emuva buyashintsha njengoba ubude bokugxila bushintsha.
5.Ukuhlolwa kokuzwela
Ukuzwela kungahlolwa ngokulinganisa isignali yokukhipha ephezulu kakhulu ilensi engakhiqiza ngaphansi kwezimo ezithile zokukhanya.
6.Ukuhlolwa kokuphazamiseka kwe-Chromatic
Ukuphambuka kwe-Chromatic kubhekisela enkingeni ebangelwa ukungahambisani kwamaphuzu okugxila emibala ehlukahlukene yokukhanya lapho ilensi yakha isithombe. Ukuphambuka kwe-Chromatic kungahlolwa ngokubheka ukuthi imiphetho yombala esithombeni icacile yini, noma ngokusebenzisa ishadi lokuhlola umbala elikhethekile.
7.Ukuhlolwa kokuqhathanisa
Umehluko phakathi kokukhanya phakathi kwamaphuzu akhanya kakhulu namnyama kakhulu esithombeni esikhiqizwe ilensi. Ungahlolwa ngokuqhathanisa i-patch emhlophe ne-patch emnyama noma ngokusebenzisa ishadi lokuhlola elikhethekile lokungafani (njengeshadi le-Stupel).

8.Ukuhlolwa kwe-Vignetting
Ukufiphaza kuyisimo sokuthi ukukhanya komphetho wesithombe kuphansi kunokwesikhungo ngenxa yokulinganiselwa kwesakhiwo selensi. Ukuhlolwa kokufiphaza kuvame ukulinganiswa kusetshenziswa isizinda esimhlophe esifanayo ukuqhathanisa umehluko wokukhanya phakathi kwesikhungo nomphetho wesithombe.
9.Ukuhlolwa kokubonakaliswa kwe-Anti-Fresnel
Ukubonakaliswa kwe-Fresnel kubhekisela esimweni sokubonakaliswa kokukhanya okungaphelele lapho kusakazeka phakathi kwemidiya ehlukene. Ngokuvamile, umthombo wokukhanya usetshenziselwa ukukhanyisa ilensi nokubuka ukubonakaliswa ukuhlola ikhono lelensi lokulwa nokubonakaliswa.
10.Ukuhlolwa kokudluliselwa
Ukudluliselwa, okungukuthi, ukudluliselwa kwelensi ku-fluorescence, kungalinganiswa kusetshenziswa imishini efana ne-spectrophotometer.
Imicabango Yokugcina:
UChuangAn wenze umklamo wokuqala kanye nokukhiqizwa kweamalensi okubona komshini, ezisetshenziswa kuzo zonke izici zezinhlelo zokubona komshini. Uma unesithakazelo noma unesidingo samalensi okubona komshini, sicela usithinte ngokushesha okukhulu.
