Phrase: Foucault knife-edge tester | Statement: [Léon Foucault, hasInstrument, Foucault knife-edge tester]

Target entity: Foucault knife-edge tester
Context triple: [Léon Foucault, hasInstrument, Foucault knife-edge tester]

• A. Foucault knife-edge test chosen
  The Foucault knife-edge test is an optical testing method used to evaluate the shape and quality of telescope mirrors by analyzing how light is blocked by a moving knife edge at the mirror’s focus.
• B. 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.
• C. Schmidt corrector plate
  A Schmidt corrector plate is a specially shaped aspheric lens used at the entrance of Schmidt-type telescopes to correct spherical aberration and produce a wide, well-corrected field of view.
• D. Dall–Kirkham telescope design
  The Dall–Kirkham telescope design is a type of reflecting telescope that uses an elliptical primary mirror and a spherical secondary mirror to provide good on-axis image quality with relatively simple, easy-to-manufacture optics.
• 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.
