Abstract
High-efficiency phase-only computer-generated holograms (CGH's) were p roduced expediently and inexpensively by a color-encoded discrete-phas e-level process. Computer-generated-hologram gray levels were mapped t o color with a high-resolution color printer, and color was mapped to phase by a broad-spectral-sensitivity high-resolution black-and-white film. Experimental results illustrating color-to-optical-density and c olor-to-phase mapping are presented for Kodak 649F film. A variety of optical interconnection elements exhibiting high diffraction efficienc ies and high contrast ratios for both on- and off-axis performance wer e fabricated by this technique. Typical experimental results are prese nted.
