Polarizer Fa'amatalaga
O polarizers e faʻamatalaina e ni nai faʻamaufaʻailoga autu, o nisi o ia mea e faʻapitoa mo le polarization optics.O pito sili ona taua o:
⊙Tuuina atu: O lenei tau e faasino i le tuʻuina atu o le moli faʻasolosolo laina i le itu o le polarization axis, poʻo le tuʻuina atu o le malamalama e leʻi faʻaogaina e ala i le polarizer.Fa'asalalauga fa'atutusa o le tu'uina atu lea o le malamalama e le'i polarized e ala i polarizer e lua ma o latou polarization axes o lo'o fa'aoga tutusa, a'o le fa'asalalauina o le felauaiga lea o le malamalama e le polarized e ala i polarizer se lua ma o latou polarization axes kolosi.Mo fa'asalalauga fa'alelei lelei o le moli fa'asolosolo fa'atasi e tutusa ma le axis polarization o le 100%, fa'asolo tutusa o le 50% ma le fa'asalalauina o le 0%.O le malamalama le polarized e mafai ona manatu o se tu'ufa'atasiga fa'afuase'i o le p- ma le s-polarized malamalama.O se polarizer laina sili ona lelei o le a na'o le tu'uina atu o se tasi o laina laina e lua, fa'aitiitia ai le malosi muamua e le'i fa'asalaina I.0i le afa, ie,I=I0/2,o lona uiga o le felauaiga tutusa (mo le malamalama le polarized) e 50%.Mo le malamalama faʻasalalau laina faʻatasi ma le malosi I0, o le malosi e tuʻuina atu e ala i se polarizer lelei, I, e mafai ona faʻamatalaina e le tulafono a Malus, ie,I=I0cos2Øo le θ o le tulimanu i le va o le faʻalavelave faʻafuaseʻi laina ma le axis polarization.Matou te vaʻaia mo tuʻu tutusa, 100% faʻasalalauga e ausia, ae mo 90 ° axes, e taʻua foi o polarizers sopo, o loʻo i ai le 0% faʻasalalauga, o lea o le faʻasalalauina o le 0%.Ae peita'i i fa'aoga moni i le lalolagi, e le mafai lava ona sa'o le 0% le fa'asalalauga, o le mea lea, o lo'o fa'ailoaina e polarizer le fua fa'atatau e pei ona fa'amatalaina i lalo, lea e mafai ona fa'aoga e iloa ai le felauaiga sa'o e ala i polarizer e lua.
⊙Fuafuaga Fa'aumatia ma le Degree o Polarization: O mea faʻapipiʻi o se polarizer laina e masani ona faʻamalamalamaina i le tikeri o le polarization poʻo le faʻaogaina lelei, ie, P = (T1-T2)/(T1+T2) ma lona fua faatatau fa'aumatia, ie, ρp=T2/T1lea o felauaiga autu o le malamalama fa'alaina laina e ala i se polarizer o le T1 ma le T2.O le T1 o le maualuga lea o le felauaiga e ala i le polarizer ma e tupu pe a tutusa le laina o le polarizer ma le polarization o le mea na tupu linearly polarized beam;O le T2 o le la'ititi la'ititi lea e ala atu i le polarizer ma e tupu pe a fa'asaga le axis o le polarizer i le fa'apipi'iina o le fa'alavelave fa'afuase'i laina fa'alava.
O le faʻaumatiaga o le faʻaogaina o se polarizer laina e masani ona faʻaalia e pei o le 1 / ρp: 1. O lenei faʻamaufaʻailoga e amata mai i lalo ifo o le 100: 1 (o lona uiga o loʻo e 100 taimi sili atu le faʻasalalauga mo le malamalama P polarized nai lo le S polarized moli) mo polarers laupepa taugofie i le 106: 1 mo polarizer tioata tioata maualuga maualuga.Ole fua ole fa'aumatiaga e masani lava ona fesuisuia'i ile umi ole galu ma le fa'alavelave fa'afuase'i ma e tatau ona iloiloina fa'atasi ma isi mea e pei ole tau, lapo'a, ma fa'asalalauga fa'asalalau mo se fa'aoga tu'uina atu.I le faʻaopoopoga i le faʻaumatia fua, e mafai ona tatou fuaina le faʻatinoga o se polarizer e ala i le faʻamalamalamaina o le lelei.O le maualuga o le faʻaogaina o le polarization e taʻua o le "faʻatusatusa", o lenei fua faʻatatau e masani ona faʻaaogaina pe a mafaufau i faʻaoga maualalo le malamalama lea e taua tele ai le gau.
⊙Fa'atagaga talia: O le fa'amalieina o le fa'ailoga pito sili lea ona tele mai le fa'asologa o le fa'asologa o le mamanu lea o le a fa'atino pea e le polarizer i totonu o fa'amatalaga.O le tele o polarizers ua mamanuina e galue i le fa'alavelave fa'afuase'i o le 0° po'o le 45°, po'o le pito a Brewster.E taua tele le fa'aoga o le taliaina mo le fa'aogaina ae e taua tele pe a galue ma fa'alava e le o fa'atasi.Wire grid ma dichroic polarizers e sili ona tele le taliaina, e oʻo atu i le taliaina atoa o le toetoe 90 °.
⊙Fausiaina: Polarizer e sau i le tele o foliga ma mamanu.O polarizers ata manifinifi o ni ata manifinifi e tutusa ma filiga mata.Polarizing plate beamsplitters e manifinifi, mafolafola ipu tuu i se tulimanu i le ave.Polarizing cube beamsplitters e aofia ai ni prisms tulimanu sa'o se lua e fa'apipi'i fa'atasi i le hypotenuse.
Birefringent polarizer e aofia ai ni prisms tioata e lua o loʻo faʻapipiʻi faʻatasi, lea e fuafua ai le pito o prisms e le mamanu polarizer patino.
⊙Va'ai manino: O le pupuni manino e masani lava ona fa'agata mo polarers birefringent ona o le maua o tioata mama mama fa'atapula'a le tele o nei polarizers.O polarizers Dichroic e tele avanoa manino e avanoa ona o la latou gaosiga e tu'uina atu i lapopo'a tetele.
⊙Ole umi ole auala: Ole umi ole moli e tatau ona alu ile polarizer.E taua mo le ta'ape, fa'aleaga faitoto'a, ma avanoa fa'atapula'aina, e mafai ona taua tele le umi o auala i polarizer birefringent ae e masani ona pupuu i polarizer dichroic.
⊙Fa'aleaga faitoto'a: O le fa'aleaga leisa e fa'amauina i mea fa'aoga fa'apea fo'i ma le mamanu polarizer, fa'atasi ai ma polarizer birefringent e masani ona i ai le pito sili ona maualuga le fa'aleagaina.O le sima e masani lava o le elemene sili ona faigofie i le faʻaleagaina o le laser, o le mafuaʻaga lea e maualuga atu ai le faʻaleagaina o mea faʻapipiʻi faʻafesoʻotaʻi poʻo polarizer birefringent ea vaʻaia.
Polarizer Filifiliga Taiala
E tele ituaiga o polarizer e aofia ai le dichroic, cube, wire grid, ma crystalline.E leai se ituaiga polarizer e lelei mo talosaga uma, e tofu lava ma ona lava malosi ma vaivaiga.
Dichroic Polarizers e tuʻuina atu se tulaga faʻapitoa faʻapitoa aʻo poloka uma isi.Faiga masani e aofia ai se substrate ufiufi tasi po o polymer dichroic ata tifaga, sandwiched lua ipu tioata.A o'o atu se ave fa'anatura e ala i mea dichroic, o se tasi o vaega polarization o le fa'alava o le fa'alava e malosi le mitiia ma le isi e alu i fafo ma le vaivai vaivai.O lea la, e mafai ona fa'aogaina le dichroic sheet polarizer e fa'aliliu ai fa'alava polarized fa'alava i fa'alava fa'alaina laina.Pe a faatusatusa i polarizing prisms, dichroic pepa polarizer ofoina atu le tele tele ma le taliaina angle.While o le ae vaai maualuga extinction i tau ratios, o le fausiaina faatapulaaina le faaaogaina mo lasers mana maualuga po o le vevela maualuga.Dichroic polarizers o lo'o maua i le tele o ituaiga, e amata mai i le taugofie o ata laminated i le sa'o maualuga fa'atusatusaga polarizer.
Dichroic polarizers mitiia le tulaga polarization le manaomia
Polarizing Cube Beamsplitters e faia e ala i le tu'ufa'atasia o prisms tulimanu taumatau e lua ma se hypotenuse ufiufi.O le faʻapipiʻi faʻapipiʻi e masani ona fausia i luga ole laiga o mea maualuga ma maualalo faʻamaufaʻailoga e atagia ai le malamalama S polarized ma faʻasalalau P. O le taunuuga e lua faʻalava faʻasolosolo i se foliga e faigofie ona faʻapipiʻi ma faʻaoga.O mea fa'apipi'i fa'apipi'i e masani ona tatalia le malosi maualuga, peita'i o mea fa'apipi'i fa'aoga e sima ai kupi e mafai ona le manuia.O lenei faiga fa'aletonu e mafai ona fa'aumatia e ala ile fa'afeso'ota'i mata.E ui e masani ona tatou vaʻaia le faʻatusatusaga maualuga mo le ave faʻasalalau, o le faʻatusatusaga faʻaalia e masani lava ona maualalo.
O fa'apolokalame fa'asologa uaea o lo'o fa'aalia ai le tele o uaea microscopic i luga o se mea tioata e fa'aliliuina le malamalama P-Polarized ma fa'aalia le malamalama S-Polarized.Ona o le natura faʻainisinia, uaea laina polarizer o loʻo faʻaalia ai se paʻu umi galu e faʻatapulaʻaina e ala i le tuʻuina atu o le mea e fai ai le mea e sili ona lelei mo fesoʻotaʻiga lautele e manaʻomia ai le faʻatusatusaga maualuga.
Polarization fa'asaga i uaea u'amea fa'asalalauina
Crystalline polarizer e tuʻuina atu se polarization manaʻomia ma faʻasese le vaega o totoe e ala i le faʻaogaina o mea birefringent o latou mea tioata.
E fa'aogaina e fa'apolokalame tioata ia mea fa'a-fa'ato'aga o le mea'ai e sui ai le tulaga fa'apipi'i o le malamalama o lo'o sau.O mea Birefringent e iai la'ititi la'ititi o fa'ailoga o le su'esu'e mo le malamalama polarized i fa'atonuga 'ese'ese e mafua ai ona fealua'i setete polarization 'ese'ese i mea i le saoasaoa eseese.
