Target entity: Fourth-order Fresnel lens Context triple: [Old Mackinac Point Lighthouse, originalLens, Fourth-order Fresnel lens]
-
A.
Fresnel lens
chosen
A Fresnel lens is a compact, lightweight lens design composed of concentric rings that allows lighthouses and other optical systems to project powerful, focused beams of light over long distances.
-
B.
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.
-
C.
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.
-
D.
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.
-
E.
Maksutov–Cassegrain telescope design
The Maksutov–Cassegrain telescope design is a compact catadioptric optical system that uses a spherical primary mirror and a meniscus corrector lens to provide long focal lengths with well-corrected, high-contrast images in a relatively short tube.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
