Rayleigh–Sommerfeld diffraction theory

Target entity: Rayleigh–Sommerfeld diffraction theory
Context triple: [Kirchhoff diffraction theory, improvedBy, Rayleigh–Sommerfeld diffraction theory]

• A. Kirchhoff diffraction theory
  Kirchhoff diffraction theory is a classical wave optics framework that models light propagation and diffraction by treating wavefronts as superpositions of secondary spherical waves emitted from an aperture.
• B. Fresnel diffraction theory
  Fresnel diffraction theory is a wave-optics framework that describes how light diffracts when source or observation distances are finite, using near-field approximations derived from the Huygens–Fresnel principle.
• C. Fraunhofer diffraction
  Fraunhofer diffraction is the far-field diffraction pattern of waves, typically light, observed when both the source and observation screen are effectively at infinite distance or made so with lenses, producing characteristic interference patterns.
• D. Huygens–Fresnel principle
  The Huygens–Fresnel principle is a fundamental concept in wave optics that explains how every point on a wavefront acts as a source of secondary wavelets whose interference determines the wave’s subsequent propagation and diffraction.
• E. Fourier optics
  Fourier optics is a branch of optics that uses Fourier transform methods to analyze and design optical systems, particularly the propagation and diffraction of light waves.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Rayleigh–Sommerfeld diffraction theory
Target entity description: Rayleigh–Sommerfeld diffraction theory is a more rigorous scalar diffraction formulation that corrects limitations in Kirchhoff’s approach by using boundary conditions consistent with the wave equation.
