Iilensi yocingoikakhulu yenzelwe ukulungisa i-parallax ye-lens yemveli yoshishino, kwaye inokuba kuluhlu oluthile lomgama, ukwenzela ukuba ukukhuliswa komfanekiso ofunyenweyo akuyi kutshintsha, isicelo esibaluleke kakhulu kwimeko yokuba into elinganisiweyo ayikho kwi umphezulu ofanayo.

Ngoyilo olukhethekileyo lwelensi, ubude bayo bokujongwa bubude, kwaye ubude bomzimba belensi budla ngokuba buncinci kunobude obugxininisiweyo.

Iimpawu zeiilensi zocingo

Uphawu lwayo kukuba inokwenza izinto ezikude zibonakale zikhulu kunobukhulu bazo bokwenyani, ngoko ke imbonakalo ekude okanye izinto zinokufotwa ngokucacileyo kwaye zichazwe ngakumbi.

Iilensi zeTelecentric zizisa ukutsiba okusemgangathweni kumatshini wokuhlola ngokuchanekileyo umbono ngokusekwe kwiimpawu zabo ezizodwa zamehlo: isisombululo esiphezulu, ubunzulu bomhlaba obanzi, ukuphazamiseka okuphantsi kakhulu, kunye noyilo olulodwa oluhambelana nokukhanya.

Iilensi zeTelecentric zisetyenziswa kakhulu kwimiboniso efana nemidlalo, izilwanyana zasendle kunye nokufota kwendalo, kunye nokuphononongwa kweenkwenkwezi, kuba le miboniso ihlala ifuna ukudubula okanye ukujonga izinto ezikude.Iilensi zeTelecentric zinokuzisa izinto ezikude "kufutshane" ngelixa zigcina ukucaca kunye neenkcukacha zomfanekiso.

Ukongeza, ngenxa yobude bojoliso olude lweiilensi zocingo, banokufikelela kwimvelaphi engasemva kunye nobunzulu obunzulu bebala, ukwenza umxholo ubonakale ngakumbi xa kufotwa, ngoko ke zikwasetyenziswa ngokubanzi kwifoto yokufota.

Ukuhlelwa okusisiseko kweilensi yocingoes

Iilensi zeTelecentric zohlulwe ikakhulu kwiilensi zetelecentric ezisecaleni kwesixhobo, iilensi zocingo ezisecaleni komfanekiso kunye neelensi zocingo ezisecaleni.

Ilensi yento

Ilensi ye-telocentric yento sisitophu sokuvula esibekwe kumfanekiso wesikweri ogxininise kwiplani yenkqubo yokukhanya, xa indawo yokuvula ibekwe kumfanekiso wenqwelomoya ekugxilwe kuyo, nokuba umgama wento uyatshintsha, umgama womfanekiso nawo uyatshintsha, kodwa ubude bomfanekiso buyatshintsha. ayitshintshi, oko kukuthi, ubungakanani bento elinganisiweyo ayitshintshi.

I-lens ye-square ye-telecentric ye-square isetyenziselwa ukulinganisa ukuchaneka kwemizi-mveliso, ukugqwetha kuncinci kakhulu, kwaye ukusebenza okuphezulu akunakuphumelela ukugqwesa.

Ilensi yesikwere somfanekiso

I-lens yecala lomfanekiso we-telecentric ibeka i-diaphragm ye-aperture kwi-object-side focal plane ukuze i-reyi eyintloko yecala-mfanekiso ihambelane ne-optical axis.Ngoko ke, nangona indawo yokufakela i-CCD chip itshintsha, ubukhulu bomfanekiso oqikelelweyo kwi-CCD chip abutshintshi.

Ilensi yamazwe amabini

Ilensi yomnxeba yamacala amabini idibanisa okuluncedo kwezi lensi zimbini zingasentla.Xa kusetyenzwa umfanekiso wemizi-mveliso, ngokuqhelekileyo kusetyenziswa iilensi ze-telecentric kuphela.Ngamanye amaxesha, iilensi zocingo kumacala omabini zisetyenziswa (ngokuqinisekileyo ixabiso liphezulu).

Kwintsimi yokulungiswa kwemifanekiso yemizi-mveliso / umbono womatshini, iilensi ze-telecentric ngokubanzi azisebenzi, ngoko ke eli shishini alizisebenzisi.
