Kugenzura imihangayiko yikirahure ni ihuriro ryingenzi mubikorwa byo gukora ibirahure, kandi uburyo bwo gukoresha ubushyuhe bukwiye kugirango ugabanye imihangayiko bizwi nabatekinisiye b'ibirahure. Nyamara, uburyo bwo gupima neza guhangayikishwa nikirahure buracyari kimwe mubibazo bitoroshye bitiranya benshi mubakora ibirahuri nabatekinisiye, kandi igereranya gakondo ryarushijeho kuba ridakwiriye gukenerwa mubisabwa mubirahure muri societe yubu. Iyi ngingo irerekana uburyo bukoreshwa muburyo bwo gupima imihangayiko muburyo burambuye, twizeye ko buzafasha kandi bukamurikira inganda zibirahure:
1. Ishingiro ryamahame yo kumenya guhangayika:
1.1 Umucyo ukabije
Birazwi neza ko urumuri ari umuyagankuba wa elegitoroniki uhindagurika mu cyerekezo cya perpendikulari yerekeza ku cyerekezo cyiterambere, kunyeganyega hejuru yimibumbe yose ihindagurika yerekeza ku cyerekezo cyimbere. Niba polarisiyasi iyungurura yemerera gusa icyerekezo runaka cyo kunyeganyega kunyura munzira yumucyo yatangijwe, urumuri rushobora kuboneka, rwitwa urumuri rwa polarize, kandi ibikoresho bya optique bikozwe ukurikije optique ni polarizer (Umuyoboro wa Polariscope).YYPL03 Umuyoboro wa Polariscope
1.2 Birefringence
Ikirahure ni isotropic kandi gifite indangagaciro imwe yo kwangirika mubyerekezo byose. Niba hari impungenge mubirahure, imiterere ya isotropique irasenywa, bigatuma indangagaciro yo guhinduka ihinduka, kandi indangagaciro yo guhagarika ibyerekezo bibiri byingenzi bitagikoreshwa ntikiri kimwe, ni ukuvuga, biganisha kuri birefringence.
1.3 Itandukaniro ryinzira nziza
Iyo urumuri rwa polarisiyasi runyuze mu kirahure gihangayikishije umubyimba t, icyerekezo cy'urumuri kigabanyijemo ibice bibiri bihindagurika mu cyerekezo cya x na y. Niba vx na vy ari umuvuduko wibice bibiri bya vector bikurikiranye, noneho igihe gisabwa cyo kunyura mubirahuri ni t / vx na t / vy, kandi ibice byombi ntibikiri hamwe, noneho hariho itandukaniro ryinzira nziza δ
