LCP-28 Abbe Imaging iyo Tijaabada shaandhaynta boosaska

Sharaxaad Gaaban:

Mabda'a sawirka Abbe wuxuu aaminsan yahay in habka sawiridda muraayadda loo qaybin karo laba tillaabo: tallaabada ugu horreysa waa in la sameeyo spectrum spatial spectrum ee diyaaradda gadaale (diyaaradaha spectrum) ee lenska iyadoo la adeegsanayo iftiin ka soo jeeda shayga, taas oo ah "qaybinta soo noqnoqda" saamaynta ay keento kala-duwanaanta;Talaabada labaad waa in si wadajir ah kor loogu qaado laydhka xajmiyada meeraha kala duwan ee diyaaradda sawirka si loo sameeyo sawirka shayga, kaas oo ah saamaynta "synthesis" ee ay keento faragelin.Labada tilaabo ee habka sawir-qaadista ayaa asal ahaan ah laba beddel oo Fourier ah.Haddii labadan isbeddel ee Fourier ay si buuxda u habboon yihiin, taas oo ah, ma jirto wax lumin ah oo macluumaad ah, markaa sawirka iyo shaygu waa inay si buuxda u siman yihiin.Haddii filtarrada kala duwan lagu dhejiyo dusha sare ee spectrum si ay u xannibaan qaybo soo noqnoqosho ah oo ka mid ah spectrum, sawirku wuu isbedeli doonaa.Shaandhaynta meel bannaan waa in la geliyo filtarrada kala duwan ee dusha sare ee nidaamka indhaha, ka saar (ama dooro inaad gudubto) wareegyada meelaha qaarkood ama beddelaan baaxaddooda iyo wejigooda, si sawirka shayga laba-geesoodka ah loo wanaajiyo sida loo baahdo.Tani sidoo kale waa nuxurka farsamaynta indhaha ee isku xidhan.
