Maqhubu a kganyang sebakeng se lokolohileng (hammoho le maqhubu a motlakase a maqhubu a mang) ke maqhubu a shear, mme tataiso ya ho thothomela ha masimo a yona a motlakase le a makenete e na le ditsela tse fapaneng tse ka bang teng karolong e tshekaletseng e otlolohileng ho ya ka tataiso ya ho ata ha maqhubu, e leng thepa ya polarization ya lesedi. Polarization e na le boleng ba bohlokwa ba tshebediso masimong a puisano e kopaneng ya optical, ho lemoha diindasteri, biomedicine, ho lemoha lefatshe hole, sesole sa sejwalejwale, difofane le lewatle.
Ka tlhaho, e le hore li tsamaee hantle, lintho tse phelang tse ngata li hlahisitse litsamaiso tsa pono tse ka khethollang polarization ea leseli. Mohlala, linotši li na le mahlo a mahlano (mahlo a mararo a le mong, mahlo a mabeli a kopaneng), ao e 'ngoe le e 'ngoe ea 'ona e nang le mahlo a manyenyane a 6,300, a thusang linotši ho fumana 'mapa oa polarization ea leseli mahlakoreng 'ohle a leholimo. Notši e ka sebelisa 'mapa oa polarization ho fumana le ho tataisa mefuta ea eona ka nepo lipalesa tseo e li fumanang. Batho ha ba na litho tsa 'mele tse tšoanang le linotši ho utloa polarization ea leseli, 'me ba hloka ho sebelisa lisebelisoa tsa maiketsetso ho utloa le ho laola polarization ea leseli. Mohlala o tloaelehileng ke tšebeliso ea likhalase tsa polarization ho tsamaisa leseli ho tsoa litšoantšong tse fapaneng ho ea mahlong a letšehali le a letona ho polarization e otlolohileng, e leng molao-motheo oa lifilimi tsa 3D cinema.
Ntlafatso ea lisebelisoa tsa taolo ea polarization ea optical tse sebetsang hantle ke senotlolo sa ho nts'etsapele theknoloji ea ts'ebeliso ea leseli le nang le polarized. Lisebelisoa tse tloaelehileng tsa taolo ea polarization li kenyelletsa jenereithara ea boemo ba polarization, scrambler, polarization analyzer, controller ea polarization, jj. Lilemong tsa morao tjena, theknoloji ea taolo ea polarization ea optical e potlakisa tsoelo-pele le ho kenella ka botebo libakeng tse 'maloa tse hlahang tsa bohlokoa bo boholo.
Ho nkapuisano ea mahlomohlala, e susumetsoang ke tlhoko ea phetiso e kholo ea data litsing tsa data, ho sebelisana ha libaka tse telele ho tsamaellanaleseliTheknoloji ea puisano e ntse e namela butle-butle ho ea lits'ebetsong tsa khokahano ea nako e khuts'oane tse amehang haholo ke litšenyehelo le tšebeliso ea matla, 'me tšebeliso ea theknoloji ea taolo ea polarization e ka fokotsa litšenyehelo le tšebeliso ea matla ea litsamaiso tsa puisano ea optical tse lumellanang tsa nako e khuts'oane.

Leha ho le jwalo, di-waveguide tsa optical tse lokisitsweng ka dikristale tsa setso tsa lithium niobate di na le mathata a phapang e nyane ya refractive index le bokgoni bo fokolang ba ho tlama masimo a optical. Ka lehlakoreng le leng, boholo ba sesebediswa bo boholo, mme ho thata ho fihlela ditlhoko tsa ntshetsopele ya kopanyo.
