Summary

[edit]
Description
Français : L'écran AG occulte partiellement la lumière issue de la source S. Au point P, les rayons issus de tous les points du front d'onde AMB se superposent au rayon direct SMP. Fresnel a utilisé ce type de figure pour introduire ses intégrales (de Fresnel) qui intègrent la contribution de tous ces rayons depuis A jusqu'à l'infini.

Source : dessiné à partir des figures de Fresnel dans Augustin Fresnel, « Mémoire sur la diffraction de la lumière », Mémoires de l'Académie des Sciences, vol. V,‎ soumis le 29 juillet 1818, publié en 1826, p. 339-476 (Fig.8) (lire en ligne=https://www.academie-sciences.fr/pdf/dossiers/Fresnel/Fresnel_pdf/Mem1818_p339.pdf)

English: The AG screen partly occults the light of the source S. At point P, secondary rays coming from all parts of the wave front AMB combine with the direct ray SMP. Fresnel used this type of figure to illustrate the introduction of his (Fresnel) integrals.
