Ukulawulwa kokucindezeleka kwengilazi kuyisixhumanisi esibaluleke kakhulu enqubweni yokukhiqiza ingilazi, futhi indlela yokusebenzisa ukwelashwa kokushisa okufanele ukulawula ukucindezeleka yaziwa kakhulu ochwepheshe bengilazi. Kodwa-ke, indlela yokulinganisa ngokunembile ukucindezeleka kwengilazi isengenye yezinkinga ezinzima ezidida iningi labakhiqizi bengilazi kanye nochwepheshe, futhi ukulinganisa okuvamile okubonakalayo sekuye kwaba okungafaneleki kakhulu ezidingweni zekhwalithi zemikhiqizo yengilazi emphakathini wanamuhla. Lesi sihloko sethula izindlela zokulinganisa ukucindezeleka ezisetshenziswa kakhulu ngokuningiliziwe, sinethemba lokuba usizo nokukhanyisa izimboni zengilazi:
1. Isisekelo semfundiso yokutholakala kokucindezeleka:
1.1 Ukukhanya okuhlanganisiwe
Kwaziwa kahle ukuthi ukukhanya kuyigagasi likagesi elidlidliza ngendlela eqondile neqondayo, lidlidliza kuzo zonke izindawo ezidlidliza ngendlela eqondile neqondayo. Uma kungeniswa isihlungi se-polarization esivumela kuphela indlela ethile yokudlidliza ukuthi idlule endleleni yokukhanya, kungatholakala ukukhanya okupholishiwe, okubizwa ngokuthi ukukhanya okupholishiwe, kanti imishini ye-optical eyenziwe ngokwezici ze-optical iyi-polarizer (Isibukeli Sokucindezeleka se-Polariscope).Isibukeli Sokucindezeleka se-Polariscope se-YYPL03
1.2 Ukuqina kwe-Birefringence
Ingilazi iyi-isotropic futhi ine-refractive index efanayo kuzo zonke izinhlangothi. Uma kukhona ukucindezeleka engilazini, izakhiwo ze-isotropic ziyabhujiswa, okubangela ukuthi i-refractive index ishintshe, futhi i-refractive index yeziqondiso ezimbili eziyinhloko zokucindezeleka ayisafani, okungukuthi, iholela ku-birefringence.
1.3 Umehluko wendlela yokukhanya
Uma ukukhanya okuhlanganisiwe kudlula engilazini ecindezelwe enobukhulu obungu-t, i-vector yokukhanya ihlukana ibe izingxenye ezimbili ezidlidliza eziqondisweni zokucindezeleka kuka-x no-y, ngokulandelana. Uma i-vx no-vy kuyijubane lezingxenye ezimbili ze-vector ngokulandelana, khona-ke isikhathi esidingekayo ukuze kudlule engilazini ngu-t/vx no-t/vy ngokulandelana, futhi izingxenye ezimbili azisavumelanisiwe, khona-ke kukhona umehluko wendlela yokukhanya δ.
