Limits of Resolution: The Rayleigh Criterion
The Rayleigh criterion stated in the equation = 1 22 D gives the smallest possible angle between point sources, or the best obtainable resolution Once this angle is found, the distance between stars can be calculated, since we are given how far away they are Solution for (a) The Rayleigh criterion for the minimum resolvable angle is = 1 22 D: (2)
Rayleigh’s criterion
minimum of the diffraction pattern of the other, a condition called Rayleigh’s criterion for resolvability From Eq 36-12, two objects that are barely resolvable by this criterion must have an angular separation u R of Since the angles are small,we can replace sin u R with u R expressed in radians: (Rayleigh’s criterion) (36-14) Human Vision

The two–point resolution problem object: two point sources, mutually incoherent (e g two stars in the night sky; two fluorescent beads in a solution) x x′ imaging system intensity pattern observed (e g with digital camera) The resolution question [Rayleigh, 1879]: when do we cease to be able to resolve the two point sources (i e , tell
Rayleigh’s Criterion and Resolving Power of Grating
The Rayleigh Criterion The Rayleigh criterion is the generally accepted criterion for the minimum resolvable detail - the imaging process is said to be diffraction-limited when the first diffraction minimum of the image of one source point coincides with the maximum of another
Resolution - Lithoguru
Rayleigh criterion becomes less accurate at predicting the influence of NA on resolution Resolution is a fundamental measure of the capability of a lithography process By applying the rigorous definition of resolution given here, resolution can be measured and used to quantify the impact

Rayleigh’s criterion for resolvability Two objects that are barely resolvable by this criterion must have an angular separation θ R = 1 22 λ/d Note: - The resolution is limited by the aperture diameter d To get a good resolution or small θ R we need d to be LARGE - The resolution is a function of the wavelength

the light observed Resolution is independent of focal length or magnification, however it is dependant on the magnitude and color of the stars observed In telescopes we use the angular value for resolution, usually reported in arc seconds Suiter: fiThe Rayleigh resolution criterion is met when the separation of the two objects is precisely

Rayleigh and Sparrow criteria were modified to suit various imaging situations, CHATURVEDI and SODHA [9], ASAKURA [4], JAISWAL and BHOGRA [10], BHATNAGAR, SIROHI and SHARMA [5], etc CARSWELL and RICHARD [11] suggested a criterion for coherent system as an extension of Rayleigh criterion The two-point resolution studies for one-
