Ungaqinisekisa njani isisombululo seelensi zezimboni? Zithini imisebenzi yazo?

1,Indlela yokuqinisekisa isisombululo seelensi zemizi-mveliso?

Ukuqinisekisa isigqibo se-ilensi yemizi-mveliso, kufuneka ezinye iindlela zokulinganisa novavanyo. Makhe sijonge iindlela ezahlukeneyo eziqhelekileyo zokuqinisekisa ukusombulula iilensi zemizi-mveliso:

Umlinganiselo we-MTF

Amandla okukwazi ukusombulula lens anokuvavanywa ngokuvavanya iModulation Transfer Function (MTF) yelens. Ukulinganiswa kweMTF kunokubonisa amandla elens okudlulisa iinkcukacha kwiifrequencies ezahlukeneyo kunye nomahluko, ngaloo ndlela kugweba ukusebenza kweresonance yelens.

Umfanekiso wovavanyo lwesisombululo

Sebenzisa umfanekiso wovavanyo lwesisombululo esinomahluko ophezulu kunye neenkcukacha ukuvavanya amandla okusombulula lensi. Ngokujonga iinkcukacha kunye neemeko zomphetho kumfanekiso, unokugweba ekuqaleni ukusebenza kwesisombululo selensi.

Sebenzisa imifanekiso ukuvavanya isisombululo

Sebenzisa iitshathi zovavanyo lwesisombululo

Kwiindlela ezisebenzayo, isisombululo selensi singavavanywa kusetyenziswa iitshathi zovavanyo lwesisombululo ezenzelwe ngokukodwa ukuvavanya isisombululo selensi. Ezi tshathi ziqulathe uthotho lwemigca emincinci okanye iipateni ezikuvumela ukuba uvavanye isisombululo selensi ngokujonga indlela ezibukhali nezibonakala ngayo ezi pateni kumfanekiso.

Sebenzisa izixhobo zobungcali

Ukuba kufuneka umlinganiselo wesisombululo ochanekileyo, izixhobo zobuchwephesha ze-optical kunye nesoftware zingasetyenziselwa ukwenza uvavanyo oluneenkcukacha ngakumbi lwesisombululo.

Jonga umgangatho womfanekiso

Ungayisebenzisa leilensi yemizi-mvelisoukudubula into nokubona ukucaca neenkcukacha zomfanekiso. Ukuba umfanekiso ucacile, uneenkcukacha, kwaye unombala ochanekileyo nomahluko, oko kuthetha ukuba ilensi inokuba nesisombululo esiphezulu.

Iinkcukacha zomenzi wesalathiso

Abavelisi belensi badla ngokubonelela ngolwazi malunga nesisombululo selensi kwiinkcukacha zemveliso, kuquka idatha efana nexabiso eliphezulu lesisombululo okanye i-MTF curve. Ungabhekisa nakwinkcukacha ezibonelelwe ngumvelisi ukuze uqonde ukusebenza kwesisombululo selensi.

2,Zithini imisebenzi ephambili yeelensi zemizi-mveliso?

Njengelensi ekhethekileyo yokukhanya kwizicelo zombono wemizi-mveliso, imisebenzi ephambili yeelensi zemizi-mveliso ibandakanya oku kulandelayo:

Ukuchongwa kunye nokuchongwa

Iilensi zoshishino, xa zidityaniswe neekhamera kunye nemithombo yokukhanya, zingasetyenziselwa ukubona iziphene zomphezulu, ukulinganisa ubukhulu, ukuchonga umbhalo okanye iipateni, kunye nokufezekisa ulawulo lomgangatho oluzenzekelayo kunye nokujonga inkqubo yemveliso. Oku kuphucula ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso.

Imisebenzi yeelensi zemizi-mveliso

Ukufunyanwa koMfanekiso

Iilensi zemizi-mvelisoIngabamba imifanekiso enesisombululo esiphezulu, engalunganga, engafaniyo kakhulu, iqinisekisa ukucaca nokuchaneka kwemifanekiso ebanjiweyo, inika isiseko esithembekileyo sokucwangciswa nokuhlaziywa kwemifanekiso okulandelayo.

Ukufunyanwa kwedatha

Idatha yemifanekiso efunyenwe ngeelensi zemizi-mveliso ingasetyenziselwa uhlalutyo lwezibalo, ukurekhoda idatha, kunye nokuchonga iimpazamo, ukunceda amashishini aphucule kwaye aphucule iinkqubo zawo zemveliso.

Isikhokelo Esibonakalayo

Iilensi zoshishino zingasetyenziselwa imisebenzi efana nokubeka izinto kwindawo yazo, ukuhambahamba, kunye nokuqaphela iinkqubo zokubona koomatshini, ukubonelela ngesikhokelo esibonakalayo seerobhothi kunye nezixhobo ezizenzekelayo, kunye nokufezekisa imveliso kunye nokusebenza okuzenzakalelayo.

Iingcinga Zokugqibela:

UChuangAn wenze uyilo lokuqala kunye nemveliso yeiilensi zoshishino, ezisetyenziswa kuzo zonke iinkalo zezicelo zoshishino. Ukuba unomdla okanye uneemfuno zeelensi zoshishino, nceda unxibelelane nathi ngokukhawuleza.
