Paper Abstract

The iterative direct binary search (DBS) algorithm for the synthesis of binary computer-generated holograms (CGH's) has been shown to yield lower reconstruction error and higher diffraction efficiency than conventional methods; but it is computationally intensive. To ameliorate this disadvantage, an acceleration technique is described which makes feasible the design of CGH's with moderate space-bandwidth product. The ability to control both the magnitude and phase of the reconstructed wavefront is an important advantage of DBS over the use of phase shaping to improve diffraction efficiency with conventional methods for CGH synthesis. To verify this capability, a procedure has been developed for measuring the phase of the reconstructed wavefront.
