Imikorere ya Diaphragm muri sisitemu ya optique

Imikorere yibanze ya aperture muri sisitemu ya optique ikubiyemo kugabanya ibiti bitagaragara, kugabanya umurima wo kureba, kuzamura ubwiza bwibishusho, no gukuraho urumuri ruzimiye, nibindi. By'umwihariko:

1. Kugabanya urumuri rwa Apamure: Aperture igena ingano yumucyo winjira muri sisitemu, bityo bikagira ingaruka kumurika no gukemura indege yishusho. Kurugero, diaphragm izenguruka kumurongo wa kamera (bakunze kwita aperture) ikora nka diaphragm ya aperture igabanya ubunini bwibiti byabaye.

2. Kugabanya Umwanya wo Kureba: Umwanya wo kureba diaphragm ikoreshwa kugirango ugabanye urugero rwishusho. Muri sisitemu yo gufotora, ikadiri ya firime ikora nka diaphragm yumurima, igabanya intera yishusho ishobora gushingwa mumwanya wibintu.

3.

4. Kurandura urumuri rutagaragara: Diaphragm ihagarika urumuri rudashushanya, bityo bikongerera itandukaniro. Diaphragm yo kurwanya inzererezi ikoreshwa mukubuza urumuri rutatanye cyangwa kugwiza urumuri kandi bikunze kuboneka muri sisitemu igoye.

Ibyiciro bya diaphragms birimo ibi bikurikira:

Aperture Diaphragm: Ibi bigena mu buryo butaziguye inguni ya aperture ya beam yerekana amashusho ahantu hamwe kandi bizwi kandi nka diafragma nziza.

Diaphragm yo mu murima: Ibi bigabanya intera igaragara yishusho ishobora gushirwaho, nko mugihe cya firime ya kamera.

Diaphragm yo Kurwanya Urusaku: Ibi bikoreshwa muguhagarika urumuri rutatanye cyangwa kugwiza urumuri rugaragara, bityo bikazamura itandukaniro no gusobanuka kwa sisitemu.

Ihame ryakazi nigikorwa cya diaphragm ihindagurika ishingiye kubushobozi bwayo bwo kugenzura ingano yumucyo unyura muguhindura ubunini bwa aperture. Muguhinduranya cyangwa kunyerera icyuma cya diaphragm, ubunini bwa aperture burashobora guhora buhindurwa, bigafasha kugenzura neza urumuri. Imikorere ya diafragma ihindagurika harimo guhindura imiterere, kugenzura ubujyakuzimu bwumurima, kurinda lens, no gushiraho urumuri, nibindi. Kurugero, mugihe cyumucyo ukomeye, kugabanya neza aperture birashobora kugabanya urumuri rwinjira mumurongo, bityo bikarinda kwangirika guterwa no gukabya.
