Abstract

Since the inception of diffractive optical elements (DOE’s) in the 1960’s, many powerful methods have been proposed to compute them. Nowadays, two kinds of techniques, both iterative, are commonly used: on one hand, techniques derived from the Direct Binary Search (DBS), on the other hand, techniques derived from Projection Onto Convex Sets (POCS) or Gerchberg and Saxton’s algorithm.
