Kuedza Kusefa Kwenzvimbo yeLCP-28 Abbe Mufananidzo Wakaratidzwa

Kuedza Kuona Nekutsvaira Nzvimbo yeLCP-28 Abbe

Tsananguro pfupi:

Musimboti weAbbe imaging unotenda kuti maitiro ekutora mifananidzo yelenzi anogona kukamurwa kuita matanho maviri: danho rekutanga kugadzira spatial spectrum pa rear focal plane (spectrum plane) yelenzi ne diffractated light kubva pachinhu, inova "frequency division" effect inokonzerwa ne diffraction; Danho rechipiri nderekuisa mwenje yema spatial frequency akasiyana pamufananidzo kuti igadzire mufananidzo wechinhu, inova "synthesis" effect inokonzerwa nekupindira. Matanho maviri ekutora mifananidzo ari maviri eFourier transforms. Kana aya maviri eFourier transforms akanyatsokodzera, kureva kuti, hapana kurasikirwa neruzivo, saka mufananidzo nechinhu chinofanira kufanana zvachose. Kana ma spatial filters akasiyana akaiswa pa spectrum surface kuti avhare zvimwe zvikamu zve spatial frequency zve spectrum, mufananidzo uchachinja. Spatial filters ndeyekuisa ma spatial filters akasiyana-siyana pa spectrum surface ye optical system, kubvisa (kana kusarudza kupfuudza) mamwe ma spatial frequency kana kuchinja amplitude ne phase, kuitira kuti mufananidzo wechinhu une mativi maviri ugone kuvandudzwa sezvinodiwa. Iyi ndiyo zvakare pfungwa ye coherent optical processing.

Kuedza
1. Simbisa kunzwisisa kwepfungwa dze spatial frequency, spatial frequency spectrum uye spatial filtering muFourier optics
2. Kuziva nzira yekuona yekusefa kwenzvimbo uye nzira dzekuita kusefa kwe-high-pass, low-pass uye directional
