Ungazihlola njani iilensi zokubona koomatshini? Zithini iindlela?

Ukuze kuqinisekiswe ukuba ilensi inokubonelela ngemifanekiso esemgangathweni ophezulu kunye nokusebenza okuthembekileyo kwiimeko ezithile zokusetyenziswa, kuyimfuneko ukwenza uvavanyo olufanelekileyo kule lensi. Ngoko ke, zeziphi iindlela zovavanyoiilensi zokubona koomatshiniKweli nqaku, siza kufunda indlela yokuvavanya iilensi zokubona komatshini.

Indlela yokuvavanya iilensi zombono womatshini

Ziziphi iindlela zokuvavanya iilensi zombono womatshini?

Uvavanyo lweelensi zokubona komatshini kufuneka luqwalasele iinkalo ezininzi zeempawu kunye neempawu zokusebenza, kwaye kufuneka lwenziwe phantsi kokusebenza kwezixhobo ezikhethekileyo kunye neengcali ukuqinisekisa ukuba iziphumo zovavanyo zichanekile kwaye ziyasebenza.

Ezi zilandelayo ziindlela eziphambili zovavanyo:

1.Uvavanyo lokujonga indawo

Ibala lembono yelensi limisela ubungakanani bendawo enokubonwa yinkqubo ye-optical, kwaye ngokuqhelekileyo linokuvavanywa ngokulinganisa ububanzi bomfanekiso owenziwe yilensi kubude obuthile be-focal.

2.Uvavanyo lokuphambuka

Ukuphambuka kubhekisa kuguquko oluvela xa ilensi iveza into yokwenyani kwiplani yomfanekiso. Kukho iintlobo ezimbini eziphambili: ukuphambuka kwebharele kunye nokuphambuka kwepincushion.

Uvavanyo lungenziwa ngokuthatha imifanekiso yokulinganisa uze emva koko wenze uhlalutyo lokulungisa ijiyometri kunye nolwe-distortion. Ungasebenzisa ikhadi lovavanyo oluqhelekileyo, njengekhadi lovavanyo elinegridi eqhelekileyo, ukujonga ukuba imigca esemaphethelweni igobile na.

3.Uvavanyo lwesisombululo

Isisombululo selensi simisela ukucaca kweenkcukacha zomfanekiso. Ke ngoko, isisombululo sesona parameter sibalulekileyo sovavanyo selensi. Sihlala sivavanywa kusetyenziswa ikhadi lovavanyo lwesisombululo esiqhelekileyo kunye nesoftware yohlalutyo ehambelanayo. Ngokwesiqhelo, isisombululo selensi sichaphazeleka zizinto ezifana nobukhulu bomngxuma kunye nobude befocal.

4.Buvavanyo lobude be-ack focal

Ubude befocal ngasemva bumgama ukusuka kwindawo yomfanekiso ukuya ngasemva kwelensi. Kwilensi enobude obuzinzileyo, ubude befocal ngasemva buzinzile, ngelixa kwilensi yokusondeza, ubude befocal ngasemva buyatshintsha njengoko ubude befocal butshintsha.

5.Uvavanyo lobuthathaka

Uvakalelo lunokuvavanywa ngokulinganisa isignali ephezulu yokukhupha enokuveliswa yilensi phantsi kweemeko ezithile zokukhanya.

6.Uvavanyo lwe-Chromatic aberration

Ukuphazamiseka kweChromatic kubhekisa kwingxaki ebangelwa kukungangqinelani kwamanqaku okugxila kwimibala eyahlukeneyo yokukhanya xa ilensi isenza umfanekiso. Ukuphazamiseka kweChromatic kunokuvavanywa ngokujonga ukuba imiphetho yombala kumfanekiso icacile na, okanye ngokusebenzisa itshathi yovavanyo lombala ekhethekileyo.

7.Uvavanyo lokwahlulahlula

Umahluko phakathi kokukhanya phakathi kwamanqaku akhanyayo namnyama kumfanekiso owenziwe yilensi. Ungavavanywa ngokuthelekisa ipetshi emhlophe nepetshi emnyama okanye ngokusebenzisa itshathi yovavanyo lomahluko ekhethekileyo (njengetshathi yeStupel).

8.Uvavanyo lwe-Vignetting

Ukuqaqamba komphetho womfanekiso yinto yokuba ukukhanya komphetho womfanekiso kuphantsi kunokwembindi ngenxa yokunqongophala kwesakhiwo selensi. Uvavanyo lokuqaqamba ludla ngokulinganiswa kusetyenziswa imvelaphi emhlophe efanayo ukuthelekisa umahluko wokukhanya phakathi kwembindi nomphetho womfanekiso.

9.Uvavanyo lokubonakalisa i-Anti-Fresnel

Ukubonakaliswa kweFresnel kubhekisa kwinto yokubonakaliswa okungaphelelanga kokukhanya xa kusasazeka phakathi kweendlela ezahlukeneyo. Ngokwesiqhelo, umthombo wokukhanya usetyenziselwa ukukhanyisa ilensi kunye nokujonga ukubonakaliswa ukuvavanya amandla okuchasana nokubonakaliswa kwelensi.

10.Uvavanyo lokudlulisa

Ukudluliselwa, oko kukuthi, ukudluliselwa kwelensi ukuya kwi-fluorescence, kunokulinganiswa kusetyenziswa izixhobo ezifana ne-spectrophotometer.
