Microscopy by reconstructed wave-fronts

Target entity: Microscopy by reconstructed wave-fronts
Context triple: [Dennis Gabor, notableWork, Microscopy by reconstructed wave-fronts]

• A. Zernike phase-contrast method
  The Zernike phase-contrast method is a microscopy technique that converts phase shifts in light passing through transparent specimens into intensity differences, enabling detailed visualization of living cells and other unstained samples.
• B. Rayleigh–Sommerfeld diffraction theory
  Rayleigh–Sommerfeld diffraction theory is a more rigorous scalar diffraction formulation that corrects limitations in Kirchhoff’s approach by using boundary conditions consistent with the wave equation.
• 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. 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.
• E. Fresnel diffraction theory
  Fresnel diffraction theory is a wave-optics framework that describes how light diffracts when source or observation distances are finite, using near-field approximations derived from the Huygens–Fresnel principle.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Microscopy by reconstructed wave-fronts
Target entity description: "Microscopy by reconstructed wave-fronts" is the seminal 1948 paper by Dennis Gabor that introduced the principle of holography by using reconstructed wavefronts to form images.
