Le khasiI-telecentric lensyakhelwe ngokuyinhloko ukulungisa i-parallax ye-lens yendabuko yezimboni, futhi ingaba ebangeni elithile lebanga, ukuze ukuqina kwesithombe okutholakele ngeke kuguquke, okuyisicelo esibaluleke kakhulu entweni elinganiselwe indawo efanayo.

Ngokusebenzisa i-lens ekhethekile ye-lens, ubude bayo obugxile yisikhathi eside, futhi ubude be-lens buvame ukuba buncanyana kunobude obugxile.

Izici zeama-telecentric lens

Isimo saso ukuthi kungenza izinto ezikude zivele zikhudlwana kunosayizi wazo wangempela, ngakho-ke ubuhle bendawo noma izinto zingathathwa njengezithombe zicace futhi zichazwe kabanzi.

Ama-lens we-telecentric aletha i-acleap egxuma ekuhlolweni kokunemba kwemishini okusekelwe kwizimpawu zazo ezi-optical ezihlukile: Ukulungiswa okuphezulu, ukujula okubanzi kwenkambu, nokuhlanekezelwa okuphansi okuhlukile.

Ama-Telecentc Lens asetshenziswa kabanzi kwizimo ezinjengemicimbi yezemidlalo, izilwane zasendle kanye nezithombe zemvelo, kanye nokubonwa kwezinkanyezi, ngoba lezi zigcawu zivame ukudinga ukudubula noma ukubheka izinto ezikude. Ama-lens we-telecentric angaletha izinto ezikude "eduze" ngenkathi egcina ukucaciswa nemininingwane yesithombe.

Ngaphezu kwalokho, ngenxa yobude obude bokugxila kwamalensi we-telecentric, bangakwazi ukufeza ukufiphala kwangemuva kanye nokujula kwensimu engajulile, okwenza lesi sihloko sivelele ngokwengeziwe lapho sidubula, ngakho-ke futhi kusetshenziswa kabanzi kuzithombe ezinhle kakhulu.

Ukuhlukaniswa okuyisisekelo kwamalensi we-telecentric

Ama-lens we-telecentric ahlukaniswe ngama-telececric lens ye-telecentric, ama-telececric lens kanye namalensi aseceleni.

Into lens

Object telocentric lens is the aperture stop placed on the image square focal plane of the optical system, when the aperture stop is placed on the image square focal plane, even if the object distance changes, the image distance also changes, but the image height does ungashintshi, okungukuthi, usayizi wento ephakathi ayishintshi.

Ilensi ye-Object Square Telecentric isetshenziselwa ukukalwa okunembayo kwezimboni, ukuhlanekezela kuncane kakhulu, futhi ukusebenza okuphezulu kungafinyelela ukungahlanekezeli.

Izithombe zesikwele sezithombe

Ilensi ye-telecentric ye-telecentric ibeka i-apertire diaphragm endizeni egxile entweni ukuze uthishanhloko oseceleni kwesithombe uRay uhambisana ne-axis aptical. Ngakho-ke, yize isikhundla sokufaka se-CCD chip izinguquko, usayizi wesithombe esiveziwe kwi-CCD chip uhlala ungashintshiwe.

Lens ye-BIlivatal

Ilensi ye-BILATARL telecentric lens ihlanganisa izinzuzo zamalensi amabili we-telecentric. Ekucutshungulweni kwezithombe zezimboni, ngokuvamile kuphela okwenziwa yi-telecentric lens. Ngesinye isikhathi, amalensi we-telecentric nhlangothi zombili asetshenziswa (vele intengo iphakeme).

Ensimini yombono womshini wezithombe / umshini womshini, amalensi we-telecentric ngokuvamile awasebenzi, ngakho-ke lo mkhakha ngokuyisisekelo awuzisebenzisi.
