Polarization tswj kev siv hluav taws xob kho qhov muag: "ncej lub hnub qub" ntawm lub ntiaj teb kev sib txuas lus, lub hnub qub saib xyuas kev nyab xeeb rau lub xeev polarization.
Nyob rau hauv lub ntiaj teb ntawm precision optics, lub xeev polarization lub teeb yog zoo li lub tswv yim nyob rau hauv kev tshawb fawb, thiab nws txoj kev ruaj ntseg ncaj qha txiav txim siab qhov tseeb ntawm tag nrho cov system. Polarization {{{1} Taug kev kho qhov muag ntawm polarical, raws li kev tiv thaiv kev ruaj khov, muab cov khoom siv kho qhov tseeb optical nrog lawv cov yam ntxwv tshwj xeeb.
Tsis zoo li ib qho kev sib txuas lus kev sib txuas lus kho qhov muag tau, polarization {{} Taug kev tsim cov kev ntxhov siab tshwj xeeb ntawm ob sab ntawm cov tub ntxhais ntawm fiber. Qhov kev tsim qauv no tau ua rau ob lub orthogonal polarization hom nyob rau hauv cov fiber ruaj khov, ua tau zoo rau kev sib txuas ntawm kev sib txuas ntawm cov qauv. Nws yog zoo li tso tawm cov kev mob siab rau "ob - txoj kab kev" rau lub teeb} txoj kab kev "rau lub teeb pom kev ntawm cov cim sib txawv hauv cov nroog uas tsis muaj kev cuam tshuam nrog lwm tus. Tam sim no, cov ntsiab lus "Panda ntaus" thiab "Battie ntaus" Poltization {} tswj kev ua tau zoo ntawm cov qauv geometric sib txawv. Ntawm lawv, Panda - hom fiber, nrog nws cov kev ua tau zoo thiab kev ua tau ruaj khov, zoo} fais fab sib kis; Thaum lub pob tw - hom fiber, nrog nws cov txiaj ntsig siab birefringle, ua rau muaj txiaj ntsig zoo hauv qhov zoo hauv qhov chaw hnov.
Hauv fiber ntau optic gyroscopes, polarization {{0} Kev tswj cov ntsiab lus ntawm cov kab ke, thiab lawv cov yam ntxwv ruaj ntseg kom pom tseeb qhov tseeb. Nyob rau hauv daim teb ntawm quantum sib txuas lus, polarization {2} Taug kev nqa cov ntawv me me, muaj cov ntaub ntawv kev nyab xeeb. Nyob rau hauv high - lub zog ua lag luam laser, lawv tswj hwm polarization ntawm cov lasers, ua kom muaj kev sib txawv ntawm kev ua kom zoo. Tshwj xeeb hauv kev sib txuas siv kho qhov muag kho qhov muag, polarization- Kev tswj cov teeb meem ntawm cov khoom sib hloov, muab cov khoom siv hluav taws xob ua kom zoo nkauj, muab cov khoom siv hluav taws xob ruaj khov, muab cov khoom siv hluav taws xob ruaj khov kho, muab cov khoom siv nrawm nrawm nrawm dua. Hauv kev faib tawm cov fiber ntau lub ntsej muag siv tes ua haujlwm, lawv ua tiav siab dua- precision teeb liab kev soj ntsuam kev nyab xeeb.
Nyob rau hauv xyoo tsis ntev los no, lub polarization {{0} Nyeem cov thev naus laus zis fiber ntau dua li cov cim tseem ceeb xws li ua kom muaj kev sib piv thiab polarization. Los ntawm kev npaj kho thiab kos duab ntawm cov pas nrig ua ntej tau raug txo kom tsawg dua ntawm 0.2 DB / KM, thiab Polarization Extinity Extintert tau nce ntau dua 30 dB. Cov kev nce qib no tau nthuav dav rau daim ntawv thov tau txais kev sib tw ntawm polarization- tswj cov. Tshwj xeeb yog tsis yog tus neeg tsis lees paub yog nyob rau hauv lub "ua nyob rau hauv Suav teb 2025" tswj hwm cov thev naus laus zis tau ua tiav cov kev sib txuas tseem ceeb. Kev lag luam hauv tsev tau ua tiav cov txheej txheem tiav ntawm cov khoom npaj ua tiav, thiab cov khoom lag luam muaj zog rau kev ua haujlwm loj rau cov haujlwm loj thiab kev tiv thaiv kev tiv thaiv kev tiv thaiv kev ua teb chaws.
