Iilensi ye-telecentriciklanyelwe kakhulu ukulungisa i-parallax yelensi yezimboni yendabuko, futhi ingaba sebangeni elithile lebanga, ukuze ukukhuliswa kwesithombe okutholiwe kungashintshi, okuyisicelo esibaluleke kakhulu esimweni sokuthi into elinganisiwe ayikho endaweni efanayo.

Ngomklamo welensi ekhethekile, ubude bayo obuqondile bude kakhulu, kanti ubude obubonakalayo belensi buvame ukuba buncane kunobude obuqondile.

Izici zeamalensi e-telecentric

Isici sayo ukuthi ingenza izinto ezikude zibonakale zinkulu kunosayizi wazo wangempela, ngakho-ke indawo noma izinto ezikude zingathathwa izithombe zicace futhi zibe nemininingwane eminingi.

Amalensi e-Telecentric aletha ijubane elifanele ekuhlolweni kokunemba kombono womshini ngokusekelwe ezicini zawo ezihlukile zokukhanya: ukulungiswa okuphezulu, ukujula kwensimu okubanzi kakhulu, ukuphambuka okuphansi kakhulu, kanye nomklamo wokukhanya ohambisanayo oyingqayizivele.

Amalensi e-Telecentric asetshenziswa kabanzi ezigcawini ezifana nemicimbi yezemidlalo, izithombe zezilwane zasendle kanye nemvelo, kanye nokubuka izinkanyezi, ngoba lezi zigcawu zivame ukudinga ukudubula noma ukubuka izinto zikude. Amalensi e-Telecentric angasondeza izinto ezikude "eduze" ngenkathi egcina ukucaca nemininingwane yesithombe.

Ngaphezu kwalokho, ngenxa yobude obude bokugxilaamalensi e-telecentric, zingafinyelela ukufiphala kwangemuva kanye nokujula kwensimu okungajulile, okwenza isihloko sivelele kakhulu lapho kudutshulwa, ngakho-ke zisetshenziswa kabanzi ekuthwebuleni izithombe ze-portrait.

Ukuhlukaniswa okuyisisekelo kwamalensi e-telecentric

Amalensi e-Telecentric ahlukaniswe kakhulu ngamalensi e-telecentric aseceleni kwezinto, amalensi e-telecentric aseceleni kwesithombe kanye namalensi e-telecentric aseceleni.

Ilensi yezinto

Ilensi ye-telocentric yento iyi-aperture stop ebekwe endizeni yesithombe yesikwele esiqondile sohlelo lwe-optical, lapho i-aperture stop ibekwa endizeni yesithombe yesikwele esiqondile, noma ngabe ibanga lento lishintsha, ibanga lesithombe nalo liyashintsha, kodwa ukuphakama kwesithombe akushintshi, okungukuthi, usayizi wento elinganisiwe awushintshi.

Ilensi yesikwele se-telecentric yento isetshenziselwa ukulinganisa ngokunemba kwezimboni, ukuphambuka kuncane kakhulu, futhi ukusebenza okuphezulu akunakufeza ukuphambuka.

Umdwebo weskimu wendlela yokukhanya kwe-telecentric ohlangothini lwento

Ilensi yesikwele sesithombe

Ilensi ye-telecentric eseceleni kwesithombe ibeka i-aperture diaphragm endizeni egxile ehlangothini lento ukuze umsebe oyinhloko oseceleni kwesithombe uhambisane ne-optical axis. Ngakho-ke, yize indawo yokufaka ye-chip ye-CCD ishintsha, usayizi wesithombe esibonisiwe ku-chip ye-CCD awushintshi.

Ilensi yezinhlangothi zombili

Ilensi ye-telecentric ezinhlangothi zombili ihlanganisa izinzuzo zamalensi amabili e-telecentric angenhla. Ekucubungulweni kwezithombe zezimboni, ngokuvamile kusetshenziswa amalensi e-telecentric ezinto kuphela. Ngezinye izikhathi, kusetshenziswa amalensi e-telecentric kuzo zombili izinhlangothi (vele intengo iphakeme).

Emkhakheni wokucubungula izithombe zezimboni/ukubona komshini, amalensi e-telecentric ngokuvamile awasebenzi, ngakho-ke lo mkhakha awuwasebenzisi.
