Lub polarizer lossis tseem hu ua yoj phaj lossis retarder yog ib qho khoom siv kho qhov muag uas hloov lub xeev polarization ntawm lub teeb tsis dhau los ntawm nws.
Ob hom waveplates yog ib nrab-waveplates, uas hloov polarization kev taw qhia ntawm linearly polarized lub teeb, thiab quarter-waveplates, uas hloov linearly polarized lub teeb mus ncig polarized lub teeb thiab vice versa.Peb lub hlis twg yoj daim hlau kuj tseem siv tau los tsim elliptical polarization.
Polarizers, los yog waveplates raws li lawv kuj hu ua, yog tsim los ntawm birefringent cov ntaub ntawv (xws li quartz) uas muaj sib txawv indices ntawm refraction rau lub teeb linearly polarized raws ib los yog lwm yam ntawm ob lub perpendicular crystallographic axes.
Cov ntsiab lus polarizing yog siv rau hauv daim ntawv thov kev pom kom txo qis glare lossis kub qhov chaw, txhim kho qhov sib piv, lossis ua kev ntsuas kev ntxhov siab.Polarization kuj tseem siv tau los ntsuas kev hloov pauv hauv magnetic teb, qhov kub thiab txias, qauv molecular, kev sib cuam tshuam tshuaj lom neeg lossis kev co acoustic.Polarizers yog siv los xa ib lub xeev polarization tshwj xeeb thaum thaiv tag nrho lwm tus.Polarized lub teeb tuaj yeem muaj linear, ncig lossis elliptical polarization.
Tus cwj pwm ntawm waveplates (piv txwv li ib nrab yoj daim hlau, lub quarter yoj daim hlau, thiab lwm yam) nyob ntawm lub thickness ntawm cov siv lead ua, lub wavelength ntawm lub teeb thiab qhov kev hloov ntawm refractive index.Los ntawm kev xaiv qhov kev sib raug zoo ntawm cov kev txwv no, kev hloov pauv theem tswj tau tuaj yeem qhia txog ntawm ob lub polarization ntawm lub teeb nthwv dej, yog li hloov nws cov polarization.
Kev ua haujlwm siab nyias zaj duab xis polarizers yog tsim los siv lub xeev-of-the-art nyias zaj duab xis vapor deposition txheej tshuab rau kev ua tau zoo.Polarizers muaj nyob rau hauv polarizing txheej ntawm ob sab ntawm polarizer, los yog nrog ib tug polarizing txheej nyob rau hauv lub tswv yim sab thiab ib tug zoo-zoo multi-txheej txheej anti-reflection txheej ntawm cov zis sab.
