I-LCP-28 Abbe Imaging kanye Nokuhlolwa Kokuhlunga Kwendawo

Incazelo emfushane:

Umgomo we-Abbe imaging ukholelwa ukuthi inqubo yokuthwebula i-lens ingahlukaniswa ngezinyathelo ezimbili: isinyathelo sokuqala ukwakha i-spectrum yendawo endizeni yangemuva (indiza ye-spectrum) yelensi ngokukhanya okuhlukanisiwe kusuka entweni, okuyi "i-frequency division" umphumela obangelwa ukuhlukana;Isinyathelo sesibili siwukuba sibeke phezulu ngokuhambisanayo imishayo yamafrikhwensi ezindawo ahlukene endizeni yesithombe ukuze kwakheke isithombe sento, okuwumphumela "wokuhlanganiswa" obangelwa ukuphazamiseka.Izinyathelo ezimbili zenqubo yokuthatha izithombe ziyizinguquko ezimbili ze-Fourier.Uma lezi zinguquko ezimbili ze-Fourier zilungile ngokuphelele, okungukuthi, akukho ukulahlekelwa kolwazi, khona-ke isithombe nento kufanele kufane ngokuphelele.Uma izihlungi zendawo ezihlukene zisethwa endaweni ye-spectrum ukuze kuvinjwe izingxenye ezithile zefrikhwensi yendawo ye-spectrum, isithombe sizoshintsha.Ukuhlunga kwendawo ukubeka izihlungi ezihlukene zendawo endaweni ye-spectrum yesistimu yokubona, susa (noma ukhethe ukudlula) amafrikhwensi athile wendawo noma uguqule i-amplitude nesigaba, ukuze isithombe sento enezinhlangothi ezimbili sithuthukiswe njengoba kudingeka.Lokhu futhi kuwumnyombo wokucubungula okuhambisanayo kwe-optical.
