Fraunhofer theory

WebFraunhofer theory describes the portion of light deflection that occurs exclusively as a result of diffraction. If light encounters an obstacle for example a particle this results amongst other things in diffraction. If light … WebFraunhofer diffraction is the type of diffraction that occurs in the limit of small Fresnel number F\ll 1. In Fraunhofer diffraction, the diffraction pattern is independent of the …
