    A novel diffractive optical element (DOE) reconstructs three distinct patterns using red, green, and blue light. This breakthrough enables full-color image reconstruction in the near field, validated by simulations and experiments.

    Area of Science:

    • Optics
    • Photonics
    • Optical Engineering

    Background:

    • Diffractive optical elements (DOEs) are crucial for manipulating light.
    • Current DOEs often have limitations in multi-wavelength applications.
    • Achieving full-color reconstruction with a single element is a significant challenge.

    Purpose of the Study:

    • To present a novel design for a diffractive optical element (DOE).
    • To demonstrate the capability of this DOE to reconstruct different intensity patterns for distinct wavelengths.
    • To achieve full-color reconstruction using red, green, and blue light.

    Main Methods:

    • Design of a novel diffractive optical element (DOE).
    • Utilizing computer simulations to verify the design.

    Related Experiment Videos

  • Experimental validation of the DOE's reconstruction capabilities.

    • Main Results:

    • The novel DOE successfully reconstructs three different intensity patterns.
    • Full-color reconstruction is achieved when illuminated with red, green, and blue wavelengths.
    • Reconstruction is confirmed to occur in the near field (Fresnel domain).

    Conclusions:

    • The proposed DOE design procedure is effective.
    • This novel DOE offers practical full-color reconstruction capabilities.
    • The findings are supported by both simulation and experimental evidence.
