Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). 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).

Phrase: Sagnac interferometer | Statement: [Fourier transform spectrometer, mayUse, Sagnac interferometer]

Target entity: Sagnac interferometer
Context triple: [Fourier transform spectrometer, mayUse, Sagnac interferometer]

• A. Michelson interferometer
  The Michelson interferometer is a precision optical instrument that splits and recombines light beams to measure extremely small differences in path length, widely used in fundamental physics experiments and metrology.
• B. Mach–Zehnder interferometer
  The Mach–Zehnder interferometer is an optical device that splits and recombines light beams to produce interference patterns, widely used to demonstrate and study fundamental principles of quantum mechanics and wave interference.
• C. Arago ring
  The Arago ring is a faint, narrow planetary ring encircling Neptune, named after the French astronomer François Arago.
• D. Fizeau experiment
  The Fizeau experiment was a pioneering 19th-century physics experiment that measured the speed of light using a rotating toothed wheel and helped establish light’s finite velocity.
• E. Kennedy–Thorndike experiment
  The Kennedy–Thorndike experiment is a classic test of special relativity that examined the constancy of the speed of light using an interferometer with unequal arm lengths and varying laboratory velocity.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions

Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Sagnac interferometer
Triple: [Fourier transform spectrometer, mayUse, Sagnac interferometer]

A Sagnac interferometer is an optical device that splits and recombines light traveling in opposite directions around a closed loop to measure rotation or phase shifts with high precision.
