Yintoni i-pinhole lens? Zithini iimpawu kunye nokusetyenziswa kweelensi zePinhole?

1,Yintoni i-pinhole lens?

I-pinhole lens, njengoko igama lithetha, ngaba ilensi encinci kakhulu, i-aperture yokudubula i-pinhole kuphela, yilensi esetyenziswa ziikhamera ze-Ultra-Micro. Iilensi zePihole Sebenzisa umgaqo-nkqubo wemingxunya emincinci ekufumaneni imifanekiso kwaye ube neempawu ezizodwa kunye nokusetyenziswa kwezicelo.

2,Zithini iimpawu ze-pinhole lens?

Njengecandelo leSixhobo seKhamera elikhethekileyo, iilensi zePinhole zineempawu ezizodwa:

(1)Inkangeleko efihliweyo

I-pores yelensi yePinhole incinci kakhulu kwaye ifana nobukhulu be-pinhole. Ngenxa yobubanzi obuncinci obuncinci, ubungakanani bekhamera ye-pinhole ye-pinhole ye-computer, ihlala inobungakanani bengqekembe. Olu luyilo oluncinci lwenza ukuba ikhamera yekhamera ye-pihole ifihla ngokulula kwiindawo ezahlukeneyo, kwaye kunzima ukuyiqonda.

(2)KakhulusI-Orworioiimage

Ngenxa yoyilo olukhethekileyo lweelensi zepinhole, ubunzulu bendawo yayo bunzulu kwaye bunokudubula imifanekiso enkulu. Oku kuthetha ukuba izinto ezingaphambi kwekhamera zinokuboniswa ngokucacileyo kumgangatho wokucinga ngaphandle komgama. Ngokusekwe kolu phawu, iilensi ze-pinhole zenziwa kakuhle xa kudubula iindawo zokudubula kunye noyilo kufuna ukucaciswa okukhulu.

(3)Ubude obujolise kubude kunye ne-aperture

II-pinhole lensNgokwesiqhelo ayinabude obungahlawulelwayo kunye ne-aperture. Xa sele ifakiwe, i-engile kunye nokukhanya kokufumana ukukhanya kwelensi ilungisiwe. Nangona oku kunqunyelwe ekuguqukeni kokudubula ukuya kwinqanaba elithile, kuye kwenza ukuba iilensi zepinhole zilula kwaye kulula ukuzisebenzisa.

(4)Ukusebenza okunqongopheleyo kwiindawo ezinokukhanya

Kuba iilensi zepinhole zine-aperture encinci kunye nenani elincinci lokukhanya, isiphumo sokudubula kwiindawo ezinokukhanya esisezantsi akunakulunga. Oku kunokubangela iingxaki ezinje ngemifanekiso ephantsi kunye nokugqwetha imibala, kwaye imithombo yokukhanya eyongezelelweyo okanye izixhobo ezincedisayo ziyafuneka ukuphucula iziphumo zokudubula.

(5)Incwadana yemigaqosi-etup

Iilensi ze-pihole zihlala zinganazo izinto eziphezulu njengee-autofocus kwaye zifuna useto lwencwadi kunye nohlengahlengiso. Oku kukhulisa ubunzulu bokusebenza ukuya kwinqanaba elithile, kodwa ikwabonelela ngenkululeko engaphezulu, ivumela iifoto ukuba zilungelelanise ngokuguquguquka ngokweemfuno ezithile.

(6)Uluhlu olubanzi lwezicelo

Ukufihlwa kunye nokukhululeka kokusetyenziswa kweIilensi zePiholezenze zasetyenziswa ngokubanzi kumasimi amaninzi. Nokuba libekokhuseleko lwasekhaya, ukubek'esweni kweofisi okanye ukubeka i-ofisini yendawo yokuhlala, iilensi ze-pinhole zingadlala indima ebalulekileyo. Kwangelo xesha, basetyenziswa ngokubanzi kuphando lwezenzululwazi, ukubek'esweni ezitratweni, ukubonwa kwezilwanyana kunye namanye amasimi.

3,Zithini izicelo ze-pinhole zeelensi?

Iindawo zesicelo zeilensi zePinhole ikakhulu zibandakanya le miba ilandelayo:

(1) Ukubeka esweni ukhuseleko

Iilensi zepirhole zincinci kwaye zifihlakele, ukuze zifakwe kwizixhobo ezincinci kakhulu kwaye zisetyenziswa ukubeka esweni ukhuseleko olufihlakeleyo. Ngenxa yobungakanani bayo obuncinci, banokufihlwa ngokulula naphi na ukuba badubule indalo esingqongileyo.

(2) Ukuhlolwa kwendlela

Iilensi zepirhole nazo zidlala indima ebalulekileyo kulawulo lwezothutho lwedolophu. Zisetyenziselwa ukutyeshelwa kwendlela yokuphula itrafikhi, irekhode imigca yengozi yendlela, njl., Ukuncedisa ekuphuculeni ukhuseleko lwendlela kunye nolawulo.

(3) Intsimi yobugcisa

Iilensi zepinhole zisetyenziswa kwicandelo lobugcisa ukuvelisa iziphumo ezibonakalayo ezibonakalayo. Kuba iilensi zePinhole zine-infutha engapheliyo yentsimi, zinokwenza zombini umphambili kwaye imvelaphi icacile. Amagcisa amaninzi kunye neefoto zisebenzisa le ndlela ukwenza iphupha eliphuphayo, imvakalelo retro.

(4)Intsimi yophando yophando

Ngenxa yeempawu zeIilensi zePihole, zisetyenziswa ngokubanzi kwicandelo lophando lwezenzululwazi. Umzekelo, ekuqaliseni ngeenkwenkwezi, iilensi ze-pinhole zingasetyenziselwa ukugcina ilanga okanye amanye amabhunga asezulwini. Kwangelo xesha, iilensi zepinhole zikwanazo izixhobo ezibaluleke kakhulu ekujongisweni kweekhemikhali zekhemikhali kunye ne-atomic-calkac-cam-cam.

(5)Intsimi yezonyango

Kwi-radiology kunye namayeza ogqirha enyukliya, iilensi ze-pihole adlala indima ebalulekileyo kwiindlela zokucinga ezingahlaseli ezifana ne-pet (i-Poitron Ensungunce) kunye ne-Photon yokukhuphela

(6)Intsimi yemfundo

I-CINHHELe I-lensed isetyenziswe ngokubanzi kwimfundo, ngakumbi kwii-optics kunye nokufundisa ngokufota, ukunceda abafundi baqonde ukuba ukuqaqamba kwenziwe njani ngelensi kunye nendlela emihle ngayo.

(7)Ubuqupihotography

Ukufihlwa kweelensi zepinhole kukwayenza ifumane izicelo ezithile kwintsimi yefoto yobuqu. Abantu banokufihla i-lens ye-pinhole njengezinto zemihla ngemihla, ezinjengeebhokisi zephepha, ijeli yeshawari, izibane ezincinci, njl. Njl.

Kufuneka kuqatshelwe ukuba ngenxa yemeko efihliweyo, iilensi zepinhole nazo zisetyenziswa ngokulula ngabasengqiqweni kwimisebenzi engekho mthethweni, njengokuhamba, ukufota ngokufihlakeleyo, njl njl.

Ke ngoko, xa usebenzisaIilensi zePihole, imithetho efanelekileyo, imigaqo kunye nemilinganiselo yokuziphatha kufuneka iqwalaselwe ukuqinisekisa ukuba isetyenziswa ngokusemthethweni nangokuthotyelwa kwemigaqo.

Iingcinga zokugqibela:

Ukuba unomdla wokuthenga iintlobo ezahlukeneyo zeelensi zokujonga, ukuskena, iidrones, ikhaya, okanye naluphi na olunye usetyenziso, sinayo into oyifunayo. Nxibelelana nathi namhlanje ukuze ufunde ngakumbi malunga neelensi zethu kunye nezinye izinto.
