Webmula, Rayleigh–Sommerfeld formula, and diﬀraction’s angular spectrum transmission formula can be calculated fast using FFT. In these three classic formulas, since angu-lar spectrum transmission formula of diﬀraction has been expressed in terms of transfer function of diﬀraction con-cisely, it is easily to be resolved with FFT. However ... 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. simply medicare phone number for florida
