Ungayikhetha Kanjani Isilinganiso Esifanele Sokuphambuka Kwamalensi Ezimboni?

Ukukhetha izinga lokuguquguquka elifanele le-aberrationilensi yezimbonikudinga ukucabangela izici eziningi, njengezidingo ezithile zohlelo lokusebenza, izidingo zokunemba kokulinganisa, isabelomali sezindleko, njll. Nazi ezinye iziphakamiso kanye nokucatshangelwa kokukhetha:

1.Khomba izidingo zesicelo

Khomba izidingo ezithile zezicelo zezimboni zekhwalithi yesithombe nokunemba kokulinganisa, bese unquma amazinga ekhwalithi yesithombe adingekayo ngokusekelwe ezidingweni. Isibonelo, kwezinye izinhlelo zokusebenza ezidinga ukucaca okuphezulu kwesithombe nokunemba, kungadingeka ukukhetha ilensi yezimboni enesilinganiso esiphansi sokuphambuka.

2.Ukuqondaaukuphambukatizinhlobo

Qonda umthelela wamazinga ahlukene okuphambuka kwesithombe kukhwalithi yesithombe, okuhlanganisa ukuhlanekezela, ukuphambuka kwe-chromatic, ukusabalala kwamabala, njll., ukuze ukhethe ilensi yezimboni efaneleke kakhulu yezinhlelo zokusebenza ezithile.

Ukuphambuka kuhlukaniswe kakhulu kube ukuphambuka kwe-radial kanye nokuphambuka kwe-tangential. Ukuphambuka kwe-radial kuvame ukubonakala ngokuphambuka kwezinto emaphethelweni esithombe, kuyilapho ukuphambuka kwe-tangential kubangelwa amaphutha e-angular phakathi kwelensi kanye nendiza yokuthwebula izithombe. Eziningi zezicelo zezimboni, ukuphambuka kwe-radial cishe kuyinkinga enkulu.

3.Hlola imininingwane yelensi

Niniukukhetha ilensi, kunconywa futhi ukuhlola idatha yesilinganiso sokuphambuka ezinchazweni zayo, okuvame ukunikezwa njengephesenti noma inani lephikseli. Kuzinhlelo zokusebenza ezidinga ukulinganiswa okunembe kakhulu, kungafaneleka kakhulu ukukhetha ilensi enesilinganiso sokuphambuka esiphansi.

4.Ukuqonda indlela yokuhlola

Abakhiqizi bamalensi bavame ukunikeza idatha noma izindlela zokuhlola ukuphambuka. Ukuqonda lezi zindlela zokuhlola kungasiza ekuhloleni ngokunembile ukusebenza kokuphambuka kwelensi.

5.Cabanga ngesabelomali sezindleko

Ngokuvamile, amalensi ezimboni anezinga eliphansi lokuphambuka azobiza kakhulu. Ngakho-ke, kubalulekile ukucabangela isabelomali sezindleko ukuze kunqunywe ukuthi ngabe kudingeka ilensi yekhwalithi ephezulu.

6.Cabanga ngezinto zemvelo

Kuyadingeka futhi ukucabangela izici ezifana nezimo zokukhanya kanye nokushintsha kwezinga lokushisa endaweni yokusebenza ukuqinisekisa ukuzinza nokuthembeka kwelensi.

Ngaphezu kwesilinganiso sokuphambuka,ukukhetha ilensifuthi kudingeka kucatshangelwe ukuthi ezinye izinhlaka ezifana nesisombululo, insimu yokubuka, ubude bokugxila, njll. ziyahlangabezana yini nezidingo.

Imicabango Yokugcina:

Uma unesifiso sokuthenga izinhlobo ezahlukene zamalensi okuqapha, ukuskena, ama-drones, ikhaya elihlakaniphile, noma olunye uhlobo lokusetshenziswa, sinalokho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngamalensi ethu nezinye izesekeli.
