1,Chii chinonzi lenzi ye pinhole?
Lenzi yemuhole, sezvinoreva zita racho, igirazi diki kwazvo, mukana waro wekupfura wakakura seburi repakona, igirazi rinoshandiswa nemakamera e-ultra-micro. Magirazi epakona anoshandisa musimboti wemifananidzo yemaburi madiki kuti awane mifananidzo uye ane hunhu hwakasiyana uye mashandisirwo akasiyana.
2,Ndezvipi zvinhu zvine chekuita ne pinhole lens?
Sechikamu chakakosha chemudziyo wekamera, lenzi yepinhole ine zvimwe zvinhu zvakasiyana:
(1)Chitarisiko chakavanzika
Maburi e lenzi ye pinhole madiki zvikuru uye akafanana nehukuru hwe pinhole. Nekuda kwehukuru hwe pinhole dhayamita, saizi yekamera yese ye pinhole diki zvikuru, kazhinji saizi yemari chete. Dhizaini iyi diki inoita kuti kamera ye pinhole ive nyore kuvanda munzvimbo dzakasiyana-siyana, uye zvakaoma kuiziva.
(2)Hukuruscenarioimuroyi
Nekuda kwekugadzirwa kwakakosha kwelenzi yemugodhi, kudzika kwayo kwakadzama uye kunogona kutora mifananidzo yakakura. Izvi zvinoreva kuti zvinhu zviri pamberi pekamera zvinogona kuratidzwa zvakajeka pamusoro pemifananidzo pasinei nedaro. Zvichibva pane izvi, lenzi yemugodhi yakaita zvakanaka kana kutora mifananidzo yenzvimbo nezvivakwa zvichida kujeka kukuru.
(3)Kureba kwakasimba uye aperture
Iyolenzi ine gombakazhinji haina urefu hwefocal uye aperture inogadziriswa. Kana yangoiswa, kugona kwelenzi kugamuchira kona nechiedza zvinogadziriswa. Kunyangwe izvi zvichigumira pakuchinjika kwekupfura kusvika pamwero wakati, zvinoitawo kuti lenzi yepinhole ive nyore uye ive nyore kushandisa.
Lenzi yemugodhi
(4)Kushanda kushoma munzvimbo dzisina chiedza chakawanda
Sezvo lenzi yemugodhi ine mukana mudiki uye chiedza chishoma, kupfura kunogona kuitwa munzvimbo dzisina chiedza chakawanda. Izvi zvinogona kukonzera matambudziko akadai semifananidzo isina kujeka uye kukanganiswa kwemavara, uye mamwe manyuko echiedza kana mimwe michina yekuwedzera inodiwa kuti pfuti ibudirire.
(5)Nemaokoskugadzirira
Magirazi epinhole kazhinji haana zvinhu zvepamusoro zvakaita se autofocus uye anoda magadzirirwo nemaoko uye kugadziriswa. Izvi zvinowedzera kuoma kwekushanda kusvika pamwero wakati, asi zvinopawo rusununguko rwakawanda, zvichibvumira vafotori kugadzirisa zvinoenderana nezvinodiwa chaizvo.
(6)Mhando dzakasiyana dzemashandisirwo
Kuvanza uye nyore kushandisamagirazi ane maburi madikiita kuti ashandiswe zvakanyanya muminda yakawanda. Ingava yekutarisa kuchengetedzwa kwemba, yekutarisa mahofisi kana yekutarisa nzvimbo dzeveruzhinji, magirazi emumaburi anogona kuita basa rakakosha. Panguva imwe chete, anoshandiswawo zvakanyanya mukutsvagisa kwesainzi, yekutarisa traffic, yekutarisa mhuka nedzimwe nzvimbo.
3,Ndezvipi zvinoshandiswa nemalenzi epinhole?
Nzvimbo dzekushandisa dzema lenzi epinhole dzinosanganisira zvinhu zvinotevera:
(1) Kutarisa kuchengetedzeka
Magirazi emuchina madiki uye akavanzwa, saka anogona kuiswa mumidziyo midiki uye kushandiswa senzira yekutarisa kuchengetedzwa kwakavanzika. Nekuda kwehukuru hwawo hudiki, anogona kuvanzwa zviri nyore chero kupi kuti aone nharaunda zviri pachivande.
Lenzi yemugodhi wekutarisa kuchengetedzeka
(2) Kutarisa traffic
Magirazi emumugwagwa ane maburi ane basa rakakoshawo mukutarisira migwagwa yemumaguta. Anoshandiswa kutora mifananidzo yemhosva dzemumugwagwa, kunyora tsaona dzemumugwagwa, nezvimwewo, zvichibatsira kuvandudza kuchengetedzeka kwemotokari uye kushanda zvakanaka kwemaneja.
(3) Munda weunyanzvi
Magirazi epinhole anoshandiswa mumunda weunyanzvi kugadzira mifananidzo yakasiyana. Nekuti magirazi epinhole ane kudzika kusingaperi kwemunda, anogona kuita kuti pamberi nepashure paonekwe zvakajeka. Vanyori vazhinji nevatori vemifananidzo vanoshandisa nzira iyi kugadzira pfungwa yekurota, yekare.
(4)Nzvimbo yekutsvagisa kwesainzi
Nekuda kwehunhu hwemagirazi ane maburi madiki, anoshandiswawo zvakanyanya muongororo yesainzi. Semuenzaniso, mukuongorora kwenyeredzi, magirazi emugodhi anogona kushandiswa kuona zuva kana zvimwe zvinhu zvemudenga. Panguva imwe chete, magirazi emugodhi anoshandiswawo zvakanyanya mukutarisa mashandiro emakemikari madiki uye zviitiko zvemuviri zveatomu.
(5)Munda wezvekurapa
Mukuongorora mifananidzo ye radiology ne nuclear medicine, ma lenzi e pinhole anoita basa rakakosha muhunyanzvi hwekuona mifananidzo husingakuvadzi hwakadai sePET (positron emission tomography) uye SPECT (single photon emission computed tomography).
Lenzi yemuhole yekuongororwa nachiremba
(6)Munda wedzidzo
Magirazi emuchina wepinhole anoshandiswawo zvakanyanya mudzidzo, kunyanya mukudzidzisa ma optics nekutora mifananidzo, kubatsira vadzidzi kunzwisisa kuti chiedza chinopararira sei kuburikidza negirazi uye kuti mifananidzo inogadzirwa sei.
(7)Zvemunhuphotography
Kuvharwa kwelenzi yemugodhi wepakona kunoitawo kuti ive nemamwe mashandisirwo munyaya dzekutora mifananidzo yevanhu. Vanhu vanogona kuviga lenzi yemugodhi wepakona sezvinhu zvezuva nezuva, zvakaita semabhokisi emapepa, gel yekugeza, marambi madiki etafura, nezvimwewo, zvekutora mifananidzo yakavanzika.
Zvinofanira kucherechedzwa kuti nekuda kwehunhu hwayo hwekuvanda, magirazi epaburi retsono anoshandiswawo zviri nyore nevatyori vemutemo pakuita zvinhu zvisiri pamutemo, zvakaita sekudongorera, kutora mifananidzo muchivande, nezvimwewo, izvo zvinokanganisa zvakanyanya kuvanzika kwevagari uye chiremerera chavo.
Saka, kana uchishandisamagirazi ane maburi madiki, mitemo, mitemo uye mwero wetsika dzinofanira kucherechedzwa kuti zvive nechokwadi chekuti zvinoshandiswa zviri pamutemo uye zvinoenderana nemitemo.
Pfungwa Dzekupedzisira:
Kana muchida kutenga marudzi akasiyana-siyana emalenzi ekutarisa, ekuongorora, emadrone, epamba rakangwara, kana chero chimwe chinhu, tine zvamunoda. Taura nesu nhasi kuti udzidze zvakawanda nezvemalenzi edu nezvimwe zvinhu.
