Taw qhia rau shear-wave splitting
Thaum yoj shear nkag mus rau hauv nruab nrab anisotropic, nws tam sim ntawd muab faib ua ob hom shear vuam nrog orthogonal polarities, ib qho yog quasi-shear yoj (qSV yoj), thiab lwm qhov yog ntshiab shear yoj (SH yoj). Qhov tshwm sim no tseem hu ua birefringence, uas tshwm sim los ntawm anisotropy ntawm kev tshaj tawm.
