Isishwankathelo
I-polarization optics isetyenziselwa ukutshintsha imeko ye-polarization ye-radiation radiation. I-polarization optics yethu ibandakanya ii-polarizers, iipleyiti zamaza / ii-retarders, i-depolarizers, i-Faraday Rotators, kunye ne-isolators yamehlo ngaphezulu kwe-UV, ebonakalayo, okanye i-IR spectral ranges.
Iipleyiti zamaza, ezikwabizwa ngokuba zii-retarders, zisasaza ukukhanya kwaye zihlengahlengise imeko yayo yepolarization ngaphandle kokunciphisa, ukutenxa, okanye ukushenxisa umqadi. Benza oku ngokulibazisa (okanye ukulibazisa) enye icandelo le-polarization ngokubhekiselele kwicandelo layo le-orthogonal. Ipleyiti yamaza sisixhobo esibonakalayo esineentsimbi ezimbini eziziintloko, ezicothayo nezikhawulezayo, ezisombulula umqadi owenziweyo wesiganeko ube yimiqadi emibini ejikelezayo. Umqadi ovelayo uphinde udibanise ukwenza umqadi othile owenziwe ngepolarized. Iipleyiti zamaza zivelisa amaza azeleyo, anesiqingatha kunye nekota yokudeda. Zikwabizwa ngokuba yi-retarder okanye ipleyiti yokulibala. Ekukhanyeni okungabonakaliyo, iipleyiti zamaza zilingana neefestile - zombini zizinto ezibonakalayo ezisicaba apho ukukhanya kudlula khona.
⊙I-quarter-wave plate: xa ukukhanya kwe-linearly polarized kufakwa kwii-degrees ezingama-45 ukuya kwi-axis ye-quarter wave plate, i-output is circularized polarized, kunye ne-vice versa.
