WebThis figure plots the ratio of the numerical apertures of the condenser and objective versus the minimum resolved distance between Airy patterns (Rayleigh criterion) in units of wavelength divided by the objective aperture. When two adjacent Airy patterns reach the Rayleigh criterion, the resolution equation reduces to: D = r = 0.61λ/NA WebThe Rayleigh criterion for the diffraction limit to resolution states that two images are just resolvable when the center of the diffraction pattern of one is directly over the first …

WebThe Rayleigh criteria establishes the smallest distance between two light sources that can be resolved into separate objects. When a point source, such as a star, is examined using a circular aperture telescope, the image is a disc encircled by a number of very faint rings, rather than a point source. WebThe Rayleigh criterion specifies the minimum separation between two light sources that may be resolved into distinct objects.. When a point source, such as a star, is observed …

WebIt can be shown that, for a circular aperture of diameter D, the first minimum in the diffraction pattern occurs at \(\begin{array}{l}\Theta =1.22\frac{\lambda}{D}\end{array} \) … WebLight from different parts of the circular aperture interferes constructively and destructively. The effect is most noticeable when the aperture is small, but the effect is there for large apertures, too. Figure 1.
