LCP-28 Abbe Imaging uye Spatial Sefa Kuedza Inoratidzwa Mufananidzo

LCP-28 Abbe Imaging uye Spatial Kusefa Kuedza

Tsanangudzo Pfupi:

Iyo Abbe imaging musimboti inotenda kuti iyo yekufungidzira yelenzi inogona kukamurwa kuita nhanho mbiri: danho rekutanga kugadzira spatial spectrum pane yekumashure yakatarisa ndege (spectrum plane) yelens nechiedza chakaparadzaniswa kubva pachinhu, chinova "frequency division" mhedzisiro inokonzerwa nekusiyana;Danho rechipiri nderekunyatso kusimudzira matanda enzvimbo dzakasiyana-siyana pandege yemufananidzo kuita mufananidzo wechinhu, inova "synthesis" mhedzisiro inokonzerwa nekukanganisa.Matanho maviri emaitiro ekufungidzira anonyanya kushandurwa neFourier.Kana izvi zviviri zvinoshandura Fourier zvakanyatsonaka, kureva kuti, hapana kurasikirwa kwemashoko, ipapo mufananidzo uye chinhu chinofanira kunge chakafanana zvachose.Kana akasiyana mafirita epamhepo akaiswa pachiratidziro chepamusoro kuti avhare zvimwe zvikamu zvespatial frequency of the spectrum, mufananidzo unoshanduka.Kusefa kweSpatial kuisa mafirita akasiyana-siyana pane iyo spectrum pamusoro peiyo optical system, kubvisa (kana kusarudza kupfuudza) mamwe ma frequency enzvimbo kana kushandura amplitude nechikamu, kuitira kuti iyo-maviri-dimensional chinhu chifananidzo chigone kuvandudzwa sezvinodiwa.Ichi ndichowo musimboti wekubatana kwe optical processing.

1. Simbisa kunzwisiswa kwepfungwa dze spatial frequency, spatial frequency spectrum uye sefa yenzvimbo muFourier optics.
2. Kuziva nzira yekuona yekusefa kwenzvimbo uye nzira dzekuona yakakwira-kupfuura, yakaderera-pasi uye yakananga kusefa.
