Uwitekalensyashizweho cyane cyane kugirango ikosore parallax yinzira gakondo yinganda, kandi irashobora kuba mumwanya runaka, kugirango ibishusho byabonetse bidahinduka, nikintu gikomeye cyane cyakoreshwa murubanza ko ikintu cyapimwe kitari kuri ubuso bumwe.

Binyuze mu gishushanyo kidasanzwe, uburebure bwacyo ni burebure, kandi uburebure bwumubiri bwa lens busanzwe ari buto kuruta uburebure bwibanze.

Ibirangaindangururamajwi

Ikiranga ni uko ishobora gutuma ibintu bya kure bigaragara binini kuruta ubunini bwabyo, bityo ahantu kure cyangwa ibintu bishobora gufotorwa neza kandi birambuye.

Lens ya telecentric izana gusimbuka kwujuje ubuziranenge imashini igenzura neza hashingiwe ku miterere yihariye ya optique: imiterere ihanitse, ubujyakuzimu bwagutse bwumurima, kugoreka ultra-hasi, no gushushanya bidasanzwe.

Lens ya telecentric ikoreshwa cyane mumashusho nkibikorwa bya siporo, inyamaswa zo mu gasozi n’ifoto y’ibidukikije, hamwe n’ubushakashatsi bw’ikirere, kubera ko akenshi usanga bisaba kurasa cyangwa kureba ibintu kure. Lens ya telecentric irashobora kuzana ibintu bya kure "hafi" mugihe ukomeje gusobanuka neza nibisobanuro birambuye.

Byongeyeho, kubera uburebure burebure bwaindangururamajwi, barashobora kugera kumurongo wijimye hamwe nuburebure bwimbitse bwumurima, bigatuma ingingo igaragara cyane mugihe cyo kurasa, bityo rero ikoreshwa cyane mumafoto yerekana amashusho.

Ibyiciro by'ibanze byalenses

Indangantego ya terefegitura igabanijwemo ibice byuruhande rwibintu byerekanwa, ibishushanyo mbonera byerekanwa na televiziyo.

Ibikoresho by'ibikoresho

Ibikoresho bya telocentric lens ni aperture ihagarara yashyizwe kumashusho kwaduka yibanze ya sisitemu ya optique, mugihe ihagarikwa rya aperture rishyizwe kumashusho kare kare indege, nubwo intera intera ihindagurika, intera yishusho nayo irahinduka, ariko uburebure bwishusho burahinduka ntabwo bihinduka, ni ukuvuga, ingano yikintu yapimwe ntabwo ihinduka.

Ibikoresho bya kwaduka ya tereviziyo ikoreshwa mugupima neza inganda, kugoreka ni nto cyane, kandi imikorere yo hejuru ntishobora kugera ku kugoreka.

Igishushanyo mbonera cyumucyo wumucyo mubyerekezo

Ishusho kare

Lens ya shusho-kuruhande rwa terefegitura ishyira diaphragm ya aperture kumurongo wikintu cyerekezo cyerekezo kugirango urumuri-shusho nyamukuru imirasire ihwanye na optique. Kubwibyo, nubwo imyanya yo kwishyiriraho ya CCD chip ihinduka, ingano yishusho iteganijwe kuri chip ya CCD ntigihinduka.

Ishusho kare ya tereviziyo yumucyo inzira igishushanyo

Lens ebyiri

Ibice byombi byitumanaho bihuza ibyiza byinzira ebyiri zavuzwe haruguru. Mu gutunganya amashusho yinganda, muri rusange ibintu byifashishwa gusa. Rimwe na rimwe, ikoreshwa rya televiziyo ku mpande zombi rikoreshwa (birumvikana ko igiciro kiri hejuru).

Mu rwego rwo gutunganya amashusho yinganda / iyerekwa ryimashini, lens ya telecentric muri rusange ntabwo ikora, inganda rero ntizikoresha.
