I-Polariscope Strain Viewer Principles of Optics

Ukulawulwa koxinzelelo lweglasi likhonkco elibaluleke kakhulu kwinkqubo yokuvelisa iglasi, kwaye indlela yokusebenzisa unyango olufanelekileyo lobushushu ukulawula uxinzelelo luye lwaziwa kakhulu kwiingcali zeglasi.Nangona kunjalo, indlela yokulinganisa ngokuchanekileyo uxinzelelo lweglasi iseyenye yeengxaki ezinzima ezibhidanisa uninzi lwabavelisi beglasi kunye namagcisa, kwaye uqikelelo lobungqina bemveli luye lwaba lungafanelekanga ngakumbi kwiimfuno zomgangatho weemveliso zeglasi kuluntu lwanamhlanje.Eli nqaku lazisa iindlela zokulinganisa uxinzelelo ezisetyenziswa ngokuqhelekileyo, ngethemba lokuba luncedo kunye nokukhanyisa kwiifektri zeglasi:

1. Isiseko sethiyori sokufumanisa uxinzelelo:

1.1 Ukukhanya kwepolarized

Kuyaziwa ukuba ukukhanya liza lombane elingcangcazela lisiya kwicala elithe ngqo kwicala langaphambili, lingcangcazela kuzo zonke iindawo ezingcangcazelayo ezijonge kwicala eliya ngaphambili.Ukuba isihluzi se-polarization esivumela kuphela ulwalathiso oluthile lokungcangcazela ukuba ludlule kwindlela yokukhanya luyaziswa, ukukhanya kwe-polarized kunokufumaneka, okubizwa ngokuba kukukhanya kwe-polarized, kunye nezixhobo zokukhanya ezenziwe ngokuhambelana neempawu zokukhanya yi-polarizer.Polariscope Strain Viewer).YYPL03 iPolariscope Strain Viewer

1.2 Ukuqhawulwa kwemida kabini

Iglasi i-isotropic kwaye inesalathiso sokuphinda siphinde siphindeke kuzo zonke iindlela.Ukuba kukho uxinzelelo kwiglasi, iipropathi ze-isotropic zitshatyalaliswa, ezibangela ukuba i-index ye-refractive itshintshe, kwaye i-index refractive index of the two principal stress directions ayisekho, oko kukuthi, ukukhokelela kwi-birefringence.

1.3 Umahluko wendlela yokubona

Xa ukukhanya kwepolarized kudlula kwiglasi egxininisiweyo yobukhulu be-t, i-vector yokukhanya iyahlukana ibe ngamacandelo amabini angcangcazelayo ku-x kunye no-y wendlela yoxinzelelo, ngokulandelelana.Ukuba i-vx kunye ne-vy zizizantya zamacandelo amabini e-vector ngokulandelelanayo, ngoko ixesha elifunekayo ukudlula kwiglasi yi-t/vx kunye ne-t/vy ngokulandelelanayo, kwaye amacandelo amabini awasadityaniswanga, ngoko kukho umahluko wendlela yokubona δ
