Overview
Polarization optics inoshandiswa kushandura mamiriro epolarization yechiitiko radiation.Yedu polarization optics inosanganisira polarizers, wave plates / retarders, depolarizers, Faraday Rotators, uye optical isolator pamusoro peUV, inooneka, kana IR spectral renji.
Mawave plates, anozivikanwawo seretarders, anofambisa mwenje uye anogadzirisa mamiriro ayo epolarization pasina kudzikisira, kutsauka, kana kubvisa danda.Vanoita izvi nekudzoreredza (kana kunonoka) chimwe chikamu chepolarization maererano nechikamu chayo che orthogonal.A wave plate chinhu chemaziso chine matemo maviri makuru, anononoka uye anokurumidza, anogadzirisa chiitiko chakaporeswa danda kuita mapango maviri anoenderana perpendicular polarized.Iyo danda riri kubuda rinosanganiswa zvakare kuita rimwe danda repolarized.Wave plates anogadzira azere-, hafu- uye kota-mafungu ekunonoka.Ivo vanozivikanwa zvakare seretarder kana retardation ndiro.Muchiedza chisina kuporeswa, mahwendefa ewave akaenzana nemahwindo - ese ari maviri akafuratira optical zvikamu izvo chiedza chinopfuura.
⊙Quarter-wave plate: kana mutsara wepolarized mwenje uchiiswa pa45 madhigirii kune axis yekota wave plate, iyo inobuda inotenderedzwa polarized, uye zvinopesana.
⊙Half-wave plate: A half wave plate inotenderedza mwenje welinearized kune chero yainoda kutaridzika.Kona yekutenderera inopeta kaviri kona pakati pechiitiko chepolarized light uye optical axis.
