Hi does anybody have a working MATLAB code for Iterative Fourier Transform Algorithm (IFTA) for design of beam splitting diffractive elements. I need it urgently. Thanks in advance for help

Gerchberg-Saxton is pretty trivial to code. See the pseudo-code at <http://en.wikipedia.org/wiki/Gerchberg%E2%80%93Saxton_algorithm> for a start. It's all of about 10 lines. A good Fourier optics book like Goodman's will provide information on how to include parameters such as focal length and wavelength.
