LCP-28 Abbe Imaging ndi Spatial Seltering Experience

Kufotokozera Kwachidule:

Mfundo yojambula ya Abbe imakhulupirira kuti kujambula kwa lens kungathe kugawidwa m'masitepe awiri: sitepe yoyamba ndiyo kupanga mawonekedwe ozungulira kumbuyo kwa ndege (ndege) ya lens ndi kuwala kosiyana kuchokera ku chinthucho, chomwe ndi "Frequency division" zotsatira zoyambitsidwa ndi diffraction;Gawo lachiwiri ndikuwongolera molumikizana mafunde amitundu yosiyanasiyana pa ndege yazithunzi kuti apange chithunzi cha chinthucho, chomwe ndi "kaphatikizidwe" komwe kumachitika chifukwa cha kusokoneza.Masitepe awiri a njira yojambula ndi masinthidwe awiri a Fourier.Ngati matembenuzidwe awiriwa a Fourier ali abwino kotheratu, ndiko kuti, palibe kutayika kwa chidziwitso, ndiye kuti chithunzicho ndi chinthucho chiyenera kufanana kwathunthu.Ngati zosefera zosiyanasiyana zapamalo ziyikidwa pamwamba pa sipekitiramu kuti zitseke zigawo zina zamafupipafupi za sipekitiramu, chithunzicho chidzasintha.Kusefa kwamalo ndikuyika zosefera zosiyanasiyana pamtunda wa mawonekedwe a kuwala, kuchotsa (kapena kusankha kudutsa) maulendo ena apakati kapena kusintha matalikidwe awo ndi gawo, kuti chithunzithunzi chamitundu iwiri chiwongoleredwe ngati chikufunikira.Ichinso ndiye tanthauzo la coherent Optical processing.
