I-telecentric lens uhlobo lweIlensi ye-Optical, eyaziwa nangokuthi ilensi yethelevishini, noma ilensi ye-telephoto. Ngokusebenzisa i-lens ekhethekile, ubude bayo obugxile yisikhathi eside, futhi ubude be-lens buvame ukuba buncanyana kunobude obugxile. Isici ukuthi singamela izinto ezikude kakhulu kunesayizi yazo yangempela, ngakho-ke ingabamba ubuhle bokude noma izinto ngokucacile nangokuningiliziwe.

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-telecentric lensingaletha izinto ezikude "eduze" ngenkathi zigcina 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.

Lens ye-telecentric

1.Izici eziyinhloko ze-Telecentric lens

Umgomo osebenzayo welensi ye-telecentric ukusebenzisa isakhiwo sawo esikhethekile ukusabalalisa ukukhanya ngokulinganayo futhi usebenze isithombe esisezinzwa noma ifilimu. Lesi sici siyivumela ukuthi ifeze imiphumela engcono yokucabanga lapho kudutshulwa izigcawu kude kakhulu nendaba. Ngakho-ke, yiziphi izimfanelo ze-telecentric lens?

Ukucabanga okunengqondo okuphezulu:

Umcabango onqenqemeni weI-telecentric lensngeke igobele. Noma emaphethelweni amalensi, imigqa isagcina i-angle efanayo yokuhlangana nge-eksisi ephakathi yelensi, ngakho-ke kungathathwa izithombe eziphezulu kakhulu.

Umqondo oqinile onobukhulu obukhulu:

Ngenxa yokuqagela kwe-orthogonal, ilensi ye-telecentc ingagcina ubudlelwane obulinganayo besikhala, okwenza izithombe ezithwebula zibe nomqondo oqinile onobukhulu obuthathu.

Imigqa ehambisanayo:

Ngenxa yesakhiwo sangaphakathi esikhethekile se-Optical, ilensi ye-telecentric ingagcina ukukhanya okufaka i-lens parallel kuzo zonke izikhundla, okusho ukuthi imigqa yesithombe ethathwe i-lens izohlala iqonde ngaphandle kokugoba noma ukuguqulwa.

2.Izicelo ezisemqoka zamalensi we-telecentric

Ama-Telecentc Lens asetshenziswa kabanzi kule mikhakha elandelayo:

Izicelo zokucubungula isithombe

Emikhakheni efana nombono wekhompyutha adinga ukucubungula kwezithombe, ama-telecentric lens asetshenziswa kabanzi ngenxa yemiphumela yawo yokucabanga eqondile, eyenza ukucubungula kwesithombe kucace bha.

Izicelo zokuhlola izimboni

Ama-telecentric lens ajwayele ukusetshenziswa ekuhlolweni kwezimboni ezidinga ukucabanga okunengqondo okuphezulu.

Isicelo Sokuthwebula Izithombes

Kwezinye izithombe zobungcweti,ama-telecentric lenszisetshenziswa kaningi, njengezithombe zokwakha, izithombe zomkhiqizo, njll.

Izicelo zezithombe zezindiza nezicelo ze-Telephoto

Ezithombeni zezithombe zendiza kanye ne-telephoto Photography, ama-telecentric lens angabamba izithombe ngobukhulu obuqinile ezintathu nokunemba okuphezulu, futhi kusetshenziswa kabanzi.

Ukufundwa okuhlobene:Ngabe amalensi wezimboni ahlukaniswa kanjani? Kwehluke kanjani kumalensi ajwayelekile?
