How this entity was disambiguated

This entity first appeared as the object of triple T1463298 — 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.

Target entity: Fourier transform infrared spectroscopy
Context triple: [Michelson interferometer, usedInExperiment, Fourier transform infrared spectroscopy]

A. Fourier analysis
Fourier analysis is a mathematical method for decomposing functions or signals into sums of sinusoidal components, widely used in fields such as signal processing, physics, and engineering.
B. Fourier
Fourier is a French surname most famously associated with Jean-Baptiste Joseph Fourier, the mathematician and physicist known for developing Fourier analysis and Fourier series.
C. 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.
D. Raman effect
The Raman effect is a spectroscopic phenomenon in which light scattered by a material undergoes a change in wavelength due to interactions with the material’s molecular vibrations, providing a powerful tool for chemical and structural analysis.
E. Folded-port InfraRed Echellette
Folded-port InfraRed Echellette is a near-infrared spectrograph instrument used on large telescopes to obtain medium- to high-resolution spectra of astronomical objects.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
