Rayleigh–sommerfeld diffraction
WebDec 15, 2007 · According to scalar diffraction theory, Kirchhoff formula, … WebThe diffraction pattern can be either numerically generated data or digitally acquired optical data. The method shows the connection between a hologram (diffraction pattern) and an elemental image set of the same 3D object. We showed three examples, one of which is the digitally captured optical diffraction tomography data of an epithelium cell.
