WAVE PLAY
Ipuleti le-wave, elibizwa nangokuthi i-phase retarder, liyithuluzi le-optical eliguqula isimo sokukhanya kwe-polarization ngokukhiqiza umehluko wendlela yomehluko (noma umehluko wesigaba) phakathi kwezakhi ezimbili zepatalonal orthogonal polarization. Lapho ukukhanya kwesigameko kudlula kumapuleti egagasi anezinhlobo ezihlukile zeparamitha, ukukhanya okuphumayo kuhlukile, okungaba ukukhanya komugqa oqondile, ukukhanya okuhlanganisiwe kwe-polarized, ukukhanya okuyi-polarized, njll. Kunoma ikuphi wavelength othile, umehluko wesigaba unqunywa ngobukhulu yepuleti le-wave.
Amapulangwe e-Wave ngokuvamile enziwa ngezinto ezi-birefringent ngobukhulu obuqondile njenge-quartz, i-calcite noma i-mica, i-axis yakhe yokukhanya ihambelana nobuso obukhulu. Amapulangwe ejwayelekile ejwayelekile (kufaka phakathi amapuleti we-λ / 2 kanye ne-λ / 4 wave) asuselwa ekwakhiweni kwesikhala somoya okuvumela ukusetshenziswa kwawo kwezicelo zamandla aphezulu ngomkhawulo womonakalo ophakeme kune-10 J / cm² ngezinsimbi ezingama-20 ku-1064 nm.
Isigamu (λ / 2) Iplanethi yamagagasi
Ngemuva kokudlula kupuleti le-wave le-λ / 2, ukukhanya okuqondile komugqa kusasenkambeni yolayini, noma kunjalo, kukhona umehluko we-angle (2θ) phakathi kwendiza yokudlidliza ye-vibration ehlanganisiwe nendiza yokudlidliza yesigameko esikhanyayo. Uma u-θ = 45 °, indiza yokudlidliza yesibani sokuphuma ihambelana ngqo nendiza yokudlidliza yesibani sesigameko, okungukuthi, lapho θ = 45 °, ipuleti le-wave le-λ / 2 lingaguqula isimo se-polarization ngo-90 °.
Ikota (λ / 4) Ipulatifomu yeWave
Lapho i-angle phakathi kwesigameko sokudlidliza kwesehlakalo sokukhanya okuthelekisiwe ne-eksisi yokukhanya yepuleti le-wave θ = 45 °, ukukhanya okudlula kuplathifini we-λ / 4 kudinganiswe ngokujikeleza. Ngaphandle kwalokho, ngemuva kokudlulela epuletini le-λ / 4 wave, ukukhanya okujikelezwe yijikelezi kuzolinganiswa ngokuqondile. Ipuleti le-wave le-λ / 4 linomphumela olinganayo ne-λ / 2 wave plate lapho ivumela ukukhanya kudlule kabili.
