Ukuhlolwa Kokuthwebula Izithombe ze-LCP-28 Abbe kanye Nokuhlunga Kwendawo

Incazelo emfushane:

Umgomo we-Abbe imaging ukholelwa ukuthi inqubo yokuthwebula izithombe yelensi ingahlukaniswa ngezinyathelo ezimbili: isinyathelo sokuqala ukwakha i-spatial spectrum endizeni engemuva egxile (indiza ye-spectrum) yelensi ngokukhanya okuhlukanisiwe okuvela entweni, okuwumphumela "wokuhlukaniswa kwemvamisa" obangelwa ukuhluka; Isinyathelo sesibili ukufaka ngokuhambisanayo imisebe yamaza ahlukene endawo endizeni yesithombe ukuze kwakhiwe isithombe sento, okuwumphumela "wokwenziwa" obangelwa ukuphazamiseka. Izinyathelo ezimbili zenqubo yokuthwebula izithombe empeleni ziyizinguquko ezimbili ze-Fourier. Uma lezi zinguquko ezimbili ze-Fourier zilungile ngokuphelele, okungukuthi, akukho ukulahleka kolwazi, khona-ke isithombe nento kufanele kufane ngokuphelele. Uma izihlungi ezahlukene endawo zisethwe ebusweni be-spectrum ukuze kuvinjwe izingxenye ezithile zemvamisa endawo ze-spectrum, isithombe sizoshintsha. Ukuhlunga kwendawo ukubeka izihlungi ezahlukene endawo ebusweni be-spectrum yesistimu ye-optical, ukususa (noma ukukhetha ukudlula) amaza athile endawo noma ukushintsha ubukhulu bawo kanye nesigaba, ukuze isithombe sento esinezinhlangothi ezimbili singathuthukiswa njengoba kudingeka. Lokhu futhi kuyingqikithi yokucubungula okuhlanganisiwe kwe-optical.

Sithumelele i-imeyili

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Ukuhlolwa
1. Qinisa ukuqonda imiqondo yemvamisa yendawo, i-spatial frequency spectrum kanye nokuhlunga kwendawo ku-Fourier optics
2. Ngijwayelene nendlela yokuhlunga yendawo kanye nezindlela zokuhlunga okuhamba phezulu, okuhamba phansi kanye nokuqondisa
