Hoʻokolohua Kānana ʻĀpana a me ka LCP-28 Abbe

Wehewehe Pōkole:

Manaʻo ke kumumanaʻo kiʻi ʻo Abbe e hiki ke hoʻokaʻawale ʻia ke kaʻina hana kiʻi o kahi lens i ʻelua mau ʻanuʻu: ʻo ka hana mua, ʻo ia ke hana ʻana i kahi spectrum spatial ma ka mokulele focal hope (spectrum plane) o ka lens e ka mālamalama diffracted mai ka mea, ʻo ia ka hopena "frequency division" i hoʻokumu ʻia e ka diffraction; ʻO ka lua o ka hana, ʻo ia ke kau like 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 hoʻokumu ʻia e ka hoʻopilikia. ʻO nā ʻanuʻu ʻelua o ke kaʻina hana kiʻi he ʻelua mau hoʻololi Fourier. Inā kūpono loa kēia mau hoʻololi Fourier ʻelua, ʻo ia hoʻi, ʻaʻohe nalowale o ka ʻike, a laila pono ke kiʻi a me ka mea e like loa. Inā hoʻonohonoho ʻia nā kānana spatial like ʻole ma ka ʻili spectrum e ālai i kekahi mau ʻāpana alapine spatial o ka spectrum, e loli ke kiʻi. ʻO ka kānana spatial ke kau ʻana i nā kānana spatial like ʻole ma ka ʻili spectrum o ka ʻōnaehana optical, wehe (a koho paha e hoʻouna) i kekahi mau alapine spatial a hoʻololi paha i ko lākou amplitude a me ka pae, i hiki ke hoʻomaikaʻi ʻia ke kiʻi mea ʻelua-dimensional e like me ka mea e pono ai. ʻO kēia nō hoʻi ke ʻano o ka hana optical coherent.
