  2. Arago spot - Wikipedia

    en.wikipedia.org/wiki/Arago_spot

    Beside the demonstration of wave-behavior, the Arago spot also has a few other applications. One of the ideas is to use the Arago spot as a straight line reference in alignment systems. [ 27 ] Another is to probe aberrations in laser beams by using the spot's sensitivity to beam aberrations . [ 21 ]

  3. Huygens–Fresnel principle - Wikipedia

    en.wikipedia.org/wiki/Huygens–Fresnel_principle

    These assumptions have no obvious physical foundation, but led to predictions that agreed with many experimental observations, including the Poisson spot. Poisson was a member of the French Academy, which reviewed Fresnel's work. He used Fresnel's theory to predict that a bright spot ought to appear in the center of the shadow of a small disc ...

  5. Poisson point process - Wikipedia

    en.wikipedia.org/wiki/Poisson_point_process

    A visual depiction of a Poisson point process starting. In probability theory, statistics and related fields, a Poisson point process (also known as: Poisson random measure, Poisson random point field and Poisson point field) is a type of mathematical object that consists of points randomly located on a mathematical space with the essential feature that the points occur independently of one ...

  7. Impulse excitation technique - Wikipedia

    en.wikipedia.org/wiki/Impulse_excitation_technique

    Standard methods for the identification of the two Young's moduli E 1 and E 2 require two tensile, bending of IET tests, one on a beam cut along the 1-direction and one on a beam cut along the 2-direction. Major and minor Poisson's ratios can be identified if also the transverse strains are measured during the tensile tests.

  9. Boolean model (probability theory) - Wikipedia

    en.wikipedia.org/wiki/Boolean_model_(probability...

    Realization of Boolean model with random-radii discs. For statistics in probability theory, the Boolean-Poisson model or simply Boolean model for a random subset of the plane (or higher dimensions, analogously) is one of the simplest and most tractable models in stochastic geometry.
