Kuyesa kwa Kujambula ndi Kusefa kwa Malo a LCP-28 Abbe

Kufotokozera Kwachidule:

Mfundo ya Abbe imaging imakhulupirira kuti njira yojambulira zithunzi ya lenzi ingagawidwe m'magawo awiri: gawo loyamba ndikupanga spatial spectrum kumbuyo kwa lenzi pogwiritsa ntchito kuwala kochokera ku chinthucho, komwe ndi "kugawa kwafupipafupi" komwe kumachitika chifukwa cha diffraction; Gawo lachiwiri ndikuyika bwino ma lights a spatial frequency osiyanasiyana pa chithunzicho kuti apange chithunzi cha chinthucho, chomwe ndi "synthesis" effect yomwe imachitika chifukwa cha kusokonezedwa. Masitepe awiri a njira yojambulira zithunzi ndi ma Fourier transforms awiri. Ngati ma Fourier transforms awiriwa ndi abwino kwambiri, ndiko kuti, palibe kutayika kwa chidziwitso, ndiye kuti chithunzi ndi chinthucho ziyenera kufanana kwathunthu. Ngati ma spatial filters osiyanasiyana ayikidwa pamwamba pa spectrum kuti aletse zigawo zina za spatial frequency za spectrum, chithunzicho chidzasintha. Spatial filtering ndikuyika ma spatial filters osiyanasiyana pamwamba pa spectrum system, kuchotsa (kapena kusankha kudutsa) ma spatial frequency ena kapena kusintha ma amplitude ndi gawo lawo, kuti chithunzi cha chinthu cha miyeso iwiri chikhale chokonzedwa momwe chikufunikira. Ichi ndi chomwe chimapangitsa kuti coherent optical processing ikhale yogwirizana.
