  • suurus, mis iseloomustab optilist külgeraldusvõimet, mis saadakse kahe punktallika eraldamisel, kusjuures ühe punktallika intensiivsuskujutise esimene difraktsioonimiinimum langeb kokku teise punkti difraktsioonimaksimumiga
  • quantity characterizing the optical lateral resolution given by the separation of two point sources at which the first diffraction minimum of the intensity image of one point source coincides with the maximum of the other
Rayleighi kriteerium
Usage examples
  • Rayleighi kriteeriumi rakendatakse tavaliselt mittekoherentsete kujutissüsteemide korral ning teoreetiliselt täiusliku mittekoherentse optilise süsteemi puhul on optilise süsteemi Reyleighi kriteerium võrdne 0,61 λ0/AN.
Rayleigh criterion
Usage examples
  • The Rayleigh criterion is normally applied to incoherent imaging systems, and for a theoretically perfect, incoherent optical system with a filled objective pupil, the Reyleigh criterion of the optical system is equal to 0,61 λ0/AN.
