WebAug 28, 2024 · In summary: Having the quadratic phase modulation beyond the Rayleigh (Fraunhofer) limit [1] $\frac{2D^2}{\lambda}$ in Equation $(6)$ is legitimate but adds nothing more than numerical/analytical complications. The Fresnel approximation is replacing the square root with a quadratic expression in the complex exponential and is … WebRayleigh–Sommerfeld diffraction and Poisson’s spot 195 z xx' p r ζ χ Figure 1. The basic diffraction problem: a point source, p, illuminates an aperture and produces a diffraction pattern on an observing screen. r is the distance from a point in the aperture to a point on the observing screen. ζ and χ are the angles the incident and the diffracting rays make …
