LCP-28 Abbe Kiʻi a me Spatial kānana hoʻokolohua

ʻO ka wehewehe pōkole:

Manaʻo ka manaʻo kiʻi Abbe e hiki ke māhele ʻia ke kaʻina hana kiʻi o ka lens i ʻelua mau ʻanuʻu: ʻo ka hana mua ka hana ʻana i kahi spectrum spatial ma ka mokulele hope hope (spectrum plane) o ka lens ma o ke kukui ʻokoʻa mai ka mea, ʻo ia ka ʻO ka hopena "frequency division" ma muli o ka diffraction;ʻO ka ʻanuʻu ʻelua, ʻo ia ka hoʻopili ʻana i nā kukuna o nā alapine spatial like ʻole ma ka mokulele kiʻi e hana i kahi kiʻi o ka mea, ʻo ia ka hopena "synthesis" i hana ʻia e ke keakea.ʻO nā ʻanuʻu ʻelua o ke kaʻina hana kiʻi i ʻelua mau hoʻololi Fourier.Inā maikaʻi loa kēia mau hoʻololi Fourier ʻelua, ʻo ia hoʻi, ʻaʻohe nalowale o ka ʻike, a laila e like loa ke kiʻi a me ka mea.Inā hoʻonoho ʻia nā kānana spatial like ʻole ma ka ʻili o ka spectrum e ālai i kekahi mau ʻāpana alapine spatial o ka spectrum, e loli ke kiʻi.ʻO ka kānana spatial ka waiho ʻana i nā kānana spatial like ʻole ma ka ʻili o ka spectrum o ka ʻōnaehana optical, wehe (a koho paha e hala) i kekahi mau alapine spatial a i ʻole e hoʻololi i ko lākou amplitude a me ka pae, i hiki ke hoʻomaikaʻi ʻia ke kiʻi mea ʻelua-dimensional e like me ka makemake.ʻO kēia hoʻi ke kumu o ka hoʻoili ʻana o ka optical coherent.
