How this entity was disambiguated

This entity first appeared as the object of triple T1080743 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Kirchhoff diffraction theory
Context triple: [Fresnel diffraction theory, relatedTo, Kirchhoff diffraction theory]

A. 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.
B. 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.
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. Principles of Optics
Principles of Optics is a seminal textbook that rigorously develops the theory of electromagnetic waves and optical phenomena, profoundly shaping modern physical optics.
E. Fresnel zone plates
Fresnel zone plates are diffractive optical elements composed of concentric rings that focus light through interference rather than refraction, serving as lens alternatives in applications like X-ray and microscopy.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
