WebWe suggest tailoring of the illumination's complex degree of coherence for imaging specific two-and three-point objects with resolution far exceeding the Rayleigh limit. We first derive a formula for the image intensity via the pseudo-mode decomposition and the fast Fourier transform valid for any partially coherent illumination (Schell-like ... WebIt claims that two images are just resolved when one image’s diffraction pattern is greater than the second image’s first minimum diffraction. The formula for the smallest angular distance between two just resolvable objects is given by Rayleigh’s criterion. The formula will be: θ=1.22λ/D. Here D = circular aperture.

The angular resolution is proportional to the ratio of the wavelength, l, of the radiation divided by the telescope diameter: q = l/D. Why angular resolution is important? The angular resolution is a very important metric when determining objects (i.e. leg or hand)vs dust or particulate in a scanning field.

Resolution depends on the distance between two distinguishable radiating points. The sections below describe the theoretical estimates of resolution, but the real values may differ. The results below are based on mathematical models of Airy discs, which assumes an adequate level of contrast. In low-contrast systems, the resolution may be much lower than predicted by the theory outlined below. Real optical systems are complex, and practical difficulties often increase the di…
