Iilensi telecentricngokuyinhloko yakhelwe ukulungisa i-parallax yelensi yezimboni yendabuko, futhi ingaba ebangeni elithile lebanga, ukuze ukukhuliswa kwesithombe esitholiwe kungashintshi, okuwuhlelo olubaluleke kakhulu esimweni lapho into elinganisiwe ingekho indawo efanayo.

Ngomklamo okhethekile welensi, ubude bayo bokugxila bude ngokuqhathaniswa, futhi ubude bendawo yelensi ngokuvamile buncane kunobude bokugxila.

Izici zeamalensi e-telecentric

Isici sayo ukuthi ingenza izinto ezikude zibonakale zizinkulu kunosayizi wazo wangempela, ngakho indawo ekude noma izinto zingathathwa izithombe zicace futhi zinemininingwane eyengeziwe.

Amalensi e-Telecentric aletha ukweqa kwekhwalithi ekuhlolweni kokunemba kokubona komshini ngokusekelwe kuzici zawo zokubona ezihlukile: ukulungiswa okuphezulu, ukujula kwenkambu ebanzi kakhulu, ukuhlanekezela okuphansi kakhulu, kanye nomklamo wokukhanya ohambisanayo oyingqayizivele.

Amalensi e-telecentric asetshenziswa kakhulu ezigcawini ezifana nemicimbi yezemidlalo, izilwane zasendle kanye nezithombe zemvelo, kanye nokubhekwa kwezinkanyezi, ngoba lezi zigcawu zivame ukudinga ukudubula noma ukubuka izinto ezikude. Amalensi e-Telecentric angasondeza izinto ezikude ngenkathi egcina ukucaca nemininingwane yesithombe.

Ngaphezu kwalokho, ngenxa yobude bokugxila okude beamalensi e-telecentric, bangafinyelela ukufiphala kwengemuva kanye nokujula kwenkambu engajulile, okwenza isihloko sigqame kakhulu lapho kushuthwa, ngakho futhi zisetshenziswa kabanzi ekuthwebuleni izithombe.

Ukuhlukaniswa okuyisisekelo kweilensi telecentrices

Amalensi e-Telecentric ahlukaniswe ikakhulukazi amalensi e-telecentric ohlangothini lwento, amalensi e-telecentric aseceleni kwesithombe namalensi e-telecentric aseceleni.

Ilensi yento

Ilensi ye-telocentric yento iyisitobhi sokuvula esibekwe endizeni yesithombe esiyisikwele esigxilile sesistimu yokubona, lapho isitobhi sokuvula sibekwe endizeni egxilile yesithombe, ngisho noma ibanga lento lishintsha, ibanga lesithombe nalo liyashintsha, kodwa ubude besithombe buyashintsha. ungashintshi, okungukuthi, usayizi wento elinganisiwe awushintshi.

Ilensi yesikwele yesikwele yento isetshenziselwa ukulinganisa ukunemba kwemboni, ukuhlanekezela kuncane kakhulu, futhi ukusebenza okuphezulu akuzuzi ukuhlanekezela.

Ilensi yesikwele yesithombe

Ilensi ye-telecentric eseceleni kwesithombe ibeka i-diaphragm yokuvula endizeni egxilile yohlangothi lwento ukuze umsebe oyinhloko wohlangothi lwesithombe uhambisane ne-eksisi yokubona. Ngakho-ke, nakuba indawo yokufaka ye-CCD chip ishintsha, usayizi wesithombe esibonisiwe ku-CCD chip uhlala ungashintshiwe.

Umdwebo womzila wokukhanya oyisikwele we-telecentric

I-lens yamazwe amabili

Ilensi ye-telecentric yamazwe amabili ihlanganisa izinzuzo zamalensi amabili angenhla e-telecentric. Ekucutshungulweni kwezithombe zezimboni, ngokuvamile kusetshenziswa amalensi ezinto ze-telecentric kuphela. Ngezikhathi ezithile, kusetshenziswa amalensi e-telecentric nhlangothi zombili (yebo intengo iphakeme).

Emkhakheni wokucubungula izithombe/umbono womshini wezimboni, amalensi e-telecentric ngokuvamile awasebenzi, ngakho-ke lo mkhakha awuwasebenzisi.
