Iterative Fourier-transform algorithm applied to computer holography

Not Accessible

Your library or personal account may give you access

Abstract

In the generation of computer-generated holograms the phase is in many applications a free parameter that can be manipulated to achieve a high diffraction efficiency, a small space–bandwidth product, and a speckle-free reconstruction. An iterative algorithm to determine such phase distributions is described. Experimental verifications are given.
