Rayleigh–sommerfeld diffraction
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. WebJul 6, 2012 · One of the common digital holography reconstruction algorithms is the convolution algorithm (CA) based on Rayleigh–Sommerfeld diffraction integral formula and linearity system theory [ 13 ]. Another algorithm is the angular spectrum (AS) algorithm based on angular spectrum diffraction theory [ 13 ]. The diffraction plane sampling …
