Some results are discussed for both linear and nonlinear motions. Recent experimental results discussed by others suggest that the criterion may offer a practical means for investigating the causes of instabilities in propulsion systems.

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

WebFeb 15, 2024 · Every imaging system has a resolution limit, typically defined by Rayleigh's criterion.
