Direct calculation of a three-dimensional diffracted field
Direct calculation of a three-dimensional diffracted field is a scholarly work by Jiao Lin and Colin James Richard Sheppard, published in 2011 in ''Optics Letters''. The main subjects of the publication include geometrical optics, ptychography, diffraction, Kirchhoff's diffraction formula, transmittance, Fresnel integral, optics, Stereo display, digital holographic microscopy, physics, focus, physical optics, paraxial approximation, Fresnel number, computation, Fourier optics, Pupil function, Fresnel zone, digital image correlation, Fourier transform, Huygens–Fresnel principle, Fresnel diffraction, and Aperture. The authors present an approach to calculating the complex amplitude of a three-dimensional (3D) diffracted light field in the paraxial approximation based on a 3D Fourier transform.
