    Area of Science:

    • Optics and Photonics
    • Holography
    • Computer-Generated Holograms

    Background:

    • Traditional methods for creating phase-only computer-generated holograms (CGH) can be time-consuming and expensive.
    • Efficient CGH fabrication is crucial for advanced optical applications like optical interconnects.

    Purpose of the Study:

    • To develop an expedient and inexpensive method for producing high-efficiency phase-only CGHs.
    • To demonstrate the effectiveness of a color-encoded discrete-phase-level process for CGH fabrication.

    Main Methods:

    • A color-encoded discrete-phase-level process was employed.
    • Computer-generated hologram gray levels were mapped to color using a high-resolution color printer.
    • Color information was subsequently mapped to phase levels using broad-spectral-sensitivity high-resolution black-and-white film (Kodak 649F).
