ʻO ke kāohi ʻana i ke kaumaha o ke aniani he loulou koʻikoʻi loa ia i ke kaʻina hana aniani, a ʻo ke ʻano o ka hoʻopili ʻana i ka mālama wela kūpono e kāohi i ke kaumaha ua ʻike maikaʻi ʻia e nā loea aniani. Eia nō naʻe, pehea e ana pololei ai i ke kaumaha o ke aniani kekahi o nā pilikia paʻakikī e huikau ai ka hapa nui o nā mea hana aniani a me nā loea, a ua lilo ka manaʻo kuʻuna i mea kūpono ʻole no nā koi maikaʻi o nā huahana aniani i ke kaiāulu o kēia wā. Ke hōʻike nei kēia ʻatikala i nā ʻano ana kaumaha i hoʻohana pinepine ʻia me ka kikoʻī, me ka manaʻolana e kōkua a hoʻomālamalama i nā hale hana aniani:
1. Kumu kumumanaʻo o ka ʻike ʻana i ke kaumaha:
1.1 Mālamalama polarisa
Ua ʻike maopopo ʻia he nalu electromagnetic ka mālamalama e haʻalulu ana i kahi kuhikuhi kū pololei i ke kuhikuhi o ka holomua, e haʻalulu ana ma nā ʻili haʻalulu āpau e kū pololei ana i ke kuhikuhi o ka holomua. Inā hoʻokomo ʻia ka kānana polarization e ʻae wale ana i kahi kuhikuhi haʻalulu e hele ma ke ala mālamalama, hiki ke loaʻa ka mālamalama polarized, i kapa ʻia ʻo ka mālamalama polarized, a ʻo nā lako optical i hana ʻia e like me nā ʻano optical he polarizer (Mea Nānā i ke Kaʻina Polariscope).YYPL03 Polariscope Strain Viewer
1.2 Birefringence
He isotropic ke aniani a he like ka refractive index ma nā ʻaoʻao a pau. Inā he stress i loko o ke aniani, ua luku ʻia nā waiwai isotropic, e hoʻololi ai i ka refractive index, a ʻaʻole like ka refractive index o nā ʻaoʻao stress nui ʻelua, ʻo ia hoʻi, e alakaʻi ana i ka birefringence.
1.3 ʻOkoʻa ala Optical
Ke hele ka mālamalama polarized ma o ke aniani i hoʻoluhi ʻia me ka mānoanoa t, māhele ka vector mālamalama i ʻelua mau ʻāpana e haʻalulu ana ma nā kuhikuhi stress x a me y. Inā ʻo vx a me vy nā wikiwiki o nā ʻāpana vector ʻelua, a laila ʻo ka manawa e pono ai e hele ma o ke aniani ʻo t/vx a me t/vy, a ʻaʻole i hoʻonohonoho hou ʻia nā ʻāpana ʻelua, a laila aia kahi ʻokoʻa ala optical δ.
