Moiré deflectometer

Target entity: Moiré deflectometer
Context triple: [AEgIS experiment, uses, Moiré deflectometer]

• 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. 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.
• C. 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.
• D. Light-Space Modulator
  Light-Space Modulator is an experimental kinetic sculpture by László Moholy-Nagy that explores movement, light, and shadow through rotating metal and glass forms.
• E. 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.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Moiré deflectometer
Target entity description: A Moiré deflectometer is a precision optical instrument that measures tiny angular deviations or deflections in particle or light beams by analyzing interference-like moiré fringe patterns formed by multiple gratings.
