Magirazi e3D, anozivikanwawo se "stereoscopic glasses," magirazi akakosha anogona kushandiswa kuona mifananidzo ye3D kana mifananidzo.Magirazi eStereoscopic akakamurwa kuva marudzi mazhinji emavara, anowanzo tsvuku bhuruu uye tsvuku bhuruu.
Pfungwa iyi ndeyekutendera maziso ese kuti aone mumwe chete wemifananidzo miviri yemufananidzo we3D, uchishandisa nzira yechiedza mune inowirirana uye akasiyana mavara.Mafirimu e3D ari kuramba achizivikanwa pakati pevateereri.Parizvino, pane matatu marudzi emagirazi e3D pamusika: chromatic aberration, polarizing uye chikamu chenguva.Nheyo yacho ndeyokuti maziso maviri anogamuchira mifananidzo yakasiyana, uye uropi huchabatanidza data kubva kumativi maviri kuti iite matatu-dimensional effect.
Iyo fizikisi yemagirazi e3D
Chiedza wave is electromagnetic wave, electromagnetic wave is shear wave, shear wave vibration direction uye nzira yekuparadzira iri perpendicular.Kune mwenje wechisikigo unopararira mune imwe nzira, kutungamira kwayo kunowanikwa mumativi ese mundege perpendicular kune yekuparadzira gwara.Kana, kana iyo vibrate ine nzira imwe chete ichinzi linear polarized panguva ino, iyo yakawanda mutsara polarized, polarizing firimu ndiyo nzira iri nyore, pakati pepolarized lens firimu rine matinji matinji makristasi, akarongeka zvakaenzana mune imwe nzira yekurongeka, kuitira kuti iwe ugone kuisa mwenje wechisikigo kuti uve polarized mumaziso edu.Zvakaita se:
Musimboti wepolarized 3D magirazi ndeokuti ziso rekuruboshwe uye ziso rekurudyi remagirazi zvakateerana ane transverse polarizer uye longitudinal polarizer.Nenzira iyi, kana firimu rinoitwa uchishandisa polarized light tekinoroji rinoridzwa, mufananidzo welenzi yekuruboshwe inosefa kuburikidza neinochinjika polarizer kuti iwane transverse polarized light, uye mufananidzo wekurudyi lenzi unosefa kuburikidza nelongitudinal polarizer kuti uwane longitudinal polarized chiedza.
Kushandisa iyi mwenje wepolarized light ndizvo chaizvo zvinoda stereoscopic cinema - kuita kuti maziso ekurudyi nekuruboshwe ataridzike akasiyana zvachose.Nekushongedza mapurojekita maviri nemapolarizer, iwo mapurojekita anoronga zvakakwana polarized mafungu emwenje perpendicular kune mumwe nemumwe, uye ipapo muoni anogona kuona maziso ekurudyi nekuruboshwe emumwe nemumwe pasina kukanganisa kuburikidza neakananga magirazi.
Kare, magirazi e 3D akaiswa polarized aingoputirwa nepolarizing layer pamusoro pemagirazi akajairwa kugadzira iyo polarizing firimu, iro raive rakachipa zvakanyanya.Asi nzira iyi ine chirema, paunenge uchiona firimu kuti ugare wakatwasuka, haugone kurereka musoro, kana zvisina kudaro ichava kaviri.Iye zvino, kana uchiona bhaisikopo re3D, malenzi epolarizing anopfekwa nevateereri ane circular polarizers, kureva kuti, imwe inosiiwa polarized uye imwe iri kurudyi polarized, izvo zvinogona zvakare kuita kuti maziso ekuruboshwe nekurudyi evateereri aone mifananidzo yakasiyana, uye zvisinei kuti musoro unorerekera sei, hapazovi nemaonero maviri.

Colour musiyano modhi ndiyo yakachipa nzira yekuona mafirimu.Chishandiso chekutamba chicharatidza mifananidzo yekuruboshwe nekurudyi mune mavara akasiyana (tsvuku nebhuruu zvakajairika).Nemagirazi, ziso rekuruboshwe rinongoona mufananidzo weA (wakaita sechiedza dzvuku) uye ziso rekurudyi rinongoona mufananidzo weruvara rweB (sechiedza chebhuruu), kuitira kuti uone hutatu-dimensional kuratidzwa kwemufananidzo weziso rekuruboshwe nekurudyi.Asi kana ruvara rwuri pedyo nefirita tsvuku isati yapera kana firiji yebhuruu isati yapera, pachava nemumvuri weviri, zvakaoma kuva nemigumisiro yakakwana.Nguva refu mushure memaziso achaitawo nguva pfupi yekusarura kwemavara kunokonzerwa nechipingamupinyi.
Iyo shutter modhi inowanikwa nekuchinja pakati pekuruboshwe uye kurudyi ziso mafiramu kuti uwane 3D maitiro.Kusiyana nepolarizing, shutter mode ndeye inoshanda 3D tekinoroji.Iyo shutter 3D player inoshingaira kuchinja pakati peziso rekuruboshwe uye ziso rekurudyi.Kureva kuti, panguva imwecheteyo, iyo polarized 3D pikicha ine zvese zviri zviviri kuruboshwe nekurudyi mifananidzo panguva imwe chete, asi yevhavha inongori kuruboshwe kana kurudyi mifananidzo, uye magirazi e3D anochinja ziso rekuruboshwe nekurudyi panguva imwe chete.Kana iyo skrini inoratidza ziso rekuruboshwe, magirazi anovhura ziso rekuruboshwe uye anovhara ziso rekurudyi;Kana iyo skrini ichiratidza ziso rekurudyi, magirazi anovhura ziso rekurudyi uye anovhara ziso rekuruboshwe.Nekuti kumhanya kwekuchinja kupfupi pane yenguva pfupi yekuona kwevanhu, hazvibviri kunzwa kupenya kwemufananidzo paunenge uchiona firimu.Asi tekinoroji inochengetedza iyo yekutanga kugadziriswa kwemufananidzo, zvichiita kuti zvive nyore kune vashandisi kunakidzwa yechokwadi yakazara HD 3D pasina kusvibisa kupenya kwemufananidzo.
