For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).
Input
Phrase: Michelson interferometer | Statement: [Michelson–Morley experiment, usedInstrument, Michelson interferometer]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Michelson interferometer
Context triple: [Michelson–Morley experiment, usedInstrument, Michelson interferometer]
  • A. Michelson–Morley experiment
    The Michelson–Morley experiment was a landmark 1887 physics experiment that attempted to detect the Earth's motion through the hypothesized luminiferous aether and whose null result helped pave the way for Einstein's theory of special relativity.
  • B. Hanbury Brown and Twiss effect
    The Hanbury Brown and Twiss effect is a quantum optical phenomenon in which correlations in the arrival times of identical particles, such as photons, reveal their underlying statistical and coherence properties.
  • 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. Ritchey–Chrétien reflector
    A Ritchey–Chrétien reflector is a specialized type of reflecting telescope that uses hyperbolic primary and secondary mirrors to produce a wide, coma-free field of view ideal for professional astronomical imaging.
  • 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.
