Imigaqo yePolariscope Strain Viewer yeOptics

Ulawulo loxinzelelo lweglasi likhonkco elibaluleke kakhulu kwinkqubo yokuvelisa iglasi, kwaye indlela yokusebenzisa unyango olufanelekileyo lobushushu ukulawula uxinzelelo sele iyaziwa kakhulu ziingcali zeglasi. Nangona kunjalo, indlela yokulinganisa ngokuchanekileyo uxinzelelo lweglasi iseyenye yeengxaki ezinzima ezidida uninzi lwabavelisi beeglasi kunye neengcali, kwaye uqikelelo lwemveli olusekelwe kwimibono luye lwaba lolungafanelekanga ngakumbi kwiimfuno zomgangatho weemveliso zeglasi kuluntu lwanamhlanje. Eli nqaku lazisa ngeendlela zokulinganisa uxinzelelo ezisetyenziswa rhoqo ngokweenkcukacha, ngethemba lokuba ziya kuba luncedo kwaye zikhanyisele iifektri zeglasi:

1. Isiseko sethiyori sokuchongwa koxinzelelo:

1.1 Ukukhanya okupholisiweyo

Kuyaziwa ukuba ukukhanya ligagasi le-electromagnetic elingcangcazela kwicala elithe nkqo kwicala elingaphambili, lingcangcazela kuzo zonke iindawo ezingcangcazelayo kwicala elithe nkqo kwicala elingaphambili. Ukuba isihluzo se-polarization esivumela kuphela icala elithile lokungcangcazela ukuba lidlule kwindlela yokukhanya singeniswa, ukukhanya kwe-polarized kungafunyanwa, okubizwa ngokuba kukukhanya kwe-polarized, kwaye izixhobo ze-optical ezenziwe ngokweempawu ze-optical yi-polarizer (Isibukeli soxinzelelo lwePolariscope).Isibukeli soxinzelelo sePolariscope seYYPL03

1.2 Ukuqina kwe-Birefringence

Iglasi ayi-isotropic kwaye ine-refractive index efanayo kuzo zonke iindlela. Ukuba kukho uxinzelelo kwiglasi, iipropati ze-isotropic ziyatshatyalaliswa, nto leyo ebangela ukuba i-refractive index itshintshe, kwaye i-refractive index yeendlela ezimbini eziphambili zoxinzelelo ayisafani, oko kukuthi, ikhokelele kwi-birefringence.

1.3 Umahluko kwindlela yokujonga

Xa ukukhanya okupholazayo kudlula kwiglasi exineneyo enobukhulu obungu-t, i-light vector iyahlukana ibe ziinxalenye ezimbini ezingcangcazela kwicala le-x kunye ne-y, ngokulandelelana. Ukuba i-vx kunye ne-vy zisantya seenxalenye ezimbini ze-vector ngokulandelelana, ixesha elifunekayo lokudlula kwiglasi yi-t/vx kunye ne-t/vy ngokulandelelana, kwaye ezi nxalenye zimbini azisavumelaniswanga, ngoko kukho umahluko wendlela ye-optical δ.
